Recommendations on “Managed” Fanless Gigabit Switch 24-Port or Less

When will we consider to buy a managed fanless Gigabit switch 24-port or Less? Common situations where we use fanless Gigabit managed switches are for small office connectivity or for home lab upgrading. In these occasions, we pursue the speed of Gigabit because they can improve the end user experience or enhance work efficiency. At the same time, we require the machine to cause low noise so users in these environments will not be disturbed. As for the management functions, different people want different levels of managing of their network. But in overall managing a fanless Gigabit switch 24-port or less is not expected to be as complex as managing an fully-managed switches. Otherwise, the user experience will not be enhanced but in contrary be decreased. This post will recommend some easily managed 8-24 ports fanless Gigabit switches. For more information of whether to choose a fanless switch or with fan switch, please read the post Should You Buy a Fanless Switch or Switch With Fan?

Recommend Managed Fanless Gigabit Switch 24-Port or Less

A fanless switch usually will not be more than 24 ports. When a switch has more than 24 ports, for example, in a 48-port switch the power supply has to be big enough and there are many ships inside the box, if there’s no fans the air flow might become a problem. So the fanless Gigabit managed switches that we’re going to recommend will be 24-port or less. And they are all non-PoE switches.

Managed Fanless Gigabit Switch 24-Port

There are many fanless Gigabit switches that are 24-port in the market, and the five models that we’re going to recommend are from four brands. They are HP Procurve 1800-24G, 1810-24G smart-managed Gigabit switch, Cisco Catalyst 2960XR-24TS-I 24-port fanless Gigabit switch, FS S2800-24T4F fanless 24-port Gigabit managed switch and Zyxel GS1900-24 smart managed switch.

Table 24-port fanless gigabit managed switch

They have some characteristics in common that make them suitable for being used in places like home office and small office. The similarities of them include low power consumption and Gigabit fiber uplink ports. And of course the most important property is that they are silent in operation.

Another key factor that makes these five switches qualified in the managed fanless Gigabit switch 24-port list is their management function. These five switches are all managed switch that provide full layer 2 traffic management features and simple network management via Web GUI.

Cost-wise the HP 1800-24G, HP 1810-24G, FS S2800-24T4F and Zyxel G1900-24 are all good choices. The Cisco Catalyst 2960XR-24TS-I will cost more than the other four but it surely provides more some more advanced features belonging to layer 3. If we need stronger data transferring capability, Cisco Catalyst 2960XR-24TS-I is a good choice considering its backplane and forwarding rate.

In terms of the power consumption, we can notice that among them the two switch models FS S2800-24T4F and Zyxel G1900-24 consumes up to 20W power, while the FS S2800-24T4F provides two more combo Gigabit SFP/RJ45 ports for up-linking. The cost of buying a brand new fanless Gigabit switch 24-port FS S2800-24T4F or a Zyxel G1900-24 is near, too.

Managed Fanless Gigabit Switch 8/12-Port

If we have only a few devices to be connected to a fanless switch, then we can take 8/12-port fanless Gigabit switch into consideration. There are some good 8-port or 12-port fanless Gigabit managed switches popularly used by end users as well.

The HP 1800-8G and HP 1810-8G are two 8-port fanless Gigabit switches. They both have 8 10/100/1000BASE-T ports. They are cost-effective fanless switches if we do not require CLI management, STP (Spanning Tree Protocol) or other advanced management features. The HP 1800-8G/1810-8G has a switch capacity of 16 Gb/s and a forwarding rate of 11.9 Mpps. The maximum power rating of HP1800-8G is 18W and the HP 1810-8G is 15W. Another two 8-port fanless Gigabit switches of Cisco 2960 and 2960G are also favorable options. They are the Cisco WS-C2960G-8TC-L and Cisco WS-C2960-8TC-L.

The 12-port fanless Gigabit switch we want to recommend is Juniper EX2200-C12T-2G. It is a fanless Gigabit switch with 12 10/100/100BASE-T ports and 2 combo Gigabit SFP/RJ45 uplink ports. It is in standard 1RU package and the maximum power consumption is 30 W. In addition to all the layer 2 features, it also provides static routing.


Fanless Gigabit switch 24-port or less is best for use in environments that require low noise and Gigabit speed. And fanless Gigabit switch managed is a wise choice for users because it provides beneficial traffic control and network management ability.




What Benefits Can 10GBASE-T Copper Bring to Data Centers?

More than ten years ago 10GBASE-T was still a bud that had not shown its real beauty to us, but now it has been brought to data centers for almost ten years. A few years after 10GBASE-T copper was introduced into the market, it became widely available as LAN on Motherboard (LOM, a chipset that has been embedded directly on the motherboard and capable of network connections) or add-in adapters on servers. Why is it popularly adopted in data centers? What benefits does 10GABSE-T copper bring to data centers?

10GBASE-T copper switch and twisted pair

Plentiful Benefits of 10GBASE-T Copper Adoption

The benefits of 10GBASE-T copper can be measured in more than one aspect, including both obvious hardware part and hidden profits it can bring.

Nature Endowed Benefits

Like previous copper BASE-T standards, 10GBASE-T copper is backward compatible with 10/100/1000BASE-T. So using 10GBASE-T allows for a seamless migration from lower data rate to 10GbE. When used with already existing copper BASE-T, they can auto-negotiate to the highest performance transmission mode they both support. So old 10/100/1000BASE-T devices are still supported even if the faster Ethernet and Gigabit Ethernet copper switches in data centers are replaced by 10GBASE-T copper. This will also accelerate the expansion of 10G to the end users.

The second benefit of 10GBASE-T copper adoption is the cost-efficiency to use cheap twisted-pair copper cabling for lowest cost 10GbE deployment. In addition, it provides the advantage of carrying on the experience and expertise built on prior-generation BASE-T knowledge and training.

The third improvement is in power consumption. Comparing with 1000BASE-T, 10GBASE-T copper consumes much less power on per-Gbps per-port basis. It is possible to achieve 1W per 10GbE port with 10GBASE-T technology, making it more efficient to design high-port density 10GBASE-T switches and LOMs. In the data center scenario, when there’s need to connect thousands of servers by 10GBASE-T, it will be a great decrease in power consumption comparing with previous Gigabit copper Ethernet. Therefore it will also be a large saving on energy and money.

low power consumption

Also when compared with copper direct attached cable (DAC), 10GBASE-T copper cabling provides longer distance to server or switch than DAC, extending the cable lengths from several meters to up to 100 meters. It will be long enough to support nearly all data center topologies.

Future-proofing for 40GBASE-T

From copper fast Ethernet to copper Gigabit Ethernet, and now to 10GBASE-T copper, we have been enjoying the continuity of BASE-T networks. But the efforts on copper network does not stop at this level. Future-generation BASE-T is under development. In order to make use of the advantages of low cost twisted pair to compensate the gaps that DAC can not do, twisted pair is anticipated to support up to 30 m of structured cabling for 40GBASE-T. This will allow one interconnect in both Top of Rack and End of Row network infrastructure.

PoE ports are adopted in copper fast Ethernet PoE switches and Gigabit PoE switches. There’s potential for 10GBASE-T to support PoE technology as well. So in near future, IP devices relying on PoE are able to upgrade to higher bandwidth and users will enjoy better performance brought by the improvement.


10GBASE-T copper benefits data centers by providing convenient and cost-effective 10G solutions, reducing the power consumption, expanded cabling scale, future-proofing 40GBASE-T and 10GBASE-T PoE ability. The successive adoption of BASE-T networks will continue to benefit data centers as well as end users.


Differentiate the 3 Technologies: Switch Stacking vs Cascading vs Clustering

When we have more than one switches on hand we often seek to a better way in making use of them and managing them. There are mainly three technologies that we might use when we interconnect or combine several switches together, which are switch stacking, cascading and clustering. For many people that firstly get in touch with these terms, they can’t figure out the differences between them. Some discussions of the switch stacking versus switch clustering and switch stacking versus switch cascading have been put forward, but a comprehensive comparison between them has not been made. So this post is a discussion of switch stacking vs cascading vs clustering.

switch stacking vs cascading vs clustering

Switch Stacking vs Cascading vs Clustering

The comparison of switch stacking, cascading and clustering should be based on knowing the meaning of these technologies. So firstly we will see what switch stacking, cascading and cluster are.

What Are Switch Stacking, Cascading and Clustering?

Switch stacking is a technology that combines two or more switches together at the backplane typically via a specialized physical cable (stack cable), so they work like a single switch. The group of switches form a “stack”, and it requires a stack master. There’s also virtual stacking, where switches are stacked via Ethernet ports rather than stack cable/module. In such scenario, switch stacking vs cascading seems to be much similar. The port density or the switch capacity of a stack is the sum of the combined switches. For example, when you cascade two 24-port switches, you will get one large 48-port switch when it comes to configuration. And all the switches in the stack share a single IP address for remote administration instead of each stack unit having its own IP address. Only stackable switches are able to be stacked together. And it should be noted that, when the switches are stacked, there is no need to connect switches in the group via copper or fiber port besides the stacking ports, because the stack logically is one switch. It is like connecting 2 ports together on the same switch, which can cause loop.

By cascading more than one switch you can have multiple ports interconnecting each of your switches in the group. But they are configured and managed independently. Switches that are cascaded together should all support Spanning Tree Protocol (STP), in order to allow redundancy and to prevent loop. Generally switches of any models or from any manufacturers can be cascaded. But it does not rule out the cases that two switches can not be cascaded.

A switch cluster is a set of switches connected together, whether through common user port or special ports. One switch plays the role of cluster command switch, and other switches are cluster member switches, which are managed by the command switch. In a switch cluster only one IP address is needed (on the command switch). Not all switches can be clustered. Only specific cluster-capable switches from the same manufacturer can be clustered. And different manufacturers may use different software for clustering.

Switch Stacking vs Cascading

Where it comes to switch stacking vs cascading, the most obvious difference is that only stackable switches can be stacked while almost all switches can be cascaded. And the stackable switches are generally of the same model or at least belonging to the same manufacture.

In a switch stack, the port capacity is the combination of all the member switches and the bandwidth is also the sum of all switches. But by cascading switches, the bandwidth will not be increased. There’s even possibility of congestion at the cascade ports if you have only one connection between each switch.

The stack is managed as a whole. When you configure one switch, the change will be duplicated to every other switches in the stack, which is time-saving. However, in a switch cascade, you have to manage and configure every switch separately.

Stacking has a maximum number of stackable switches that you can have in a group. For example, you can connect up to four FS S3800-24F4S or FS S3800-24T4S in a stack. The switch cascading has limitation on the layers that you can have, which are usually the traditional three layers topology: core, aggregation and access. When the limitation is exceeded, there might be problems of latency and losing packet.

FS S3800-24F4S or FS S3800-24T4S stackable switch

Switch Stacking vs Clustering

Stacking and clustering is very similar in that a stack or a cluster both use only one IP address, and member switches are managed as a whole. So when you wan to simplify the management of multiple switches, both stacking and clustering are technologies that can be adopted.

Stacking might be a bit easier to configure since the stack can automatically recognize new stack member, while in a cluster, you have to manually add a device to be the switch cluster. The management of stack members is through a single configuration file. Cluster members have separate, individual configurations files. So the management by a stack master is complete on every stack switch, but the cluster command switch is the point of some management for all cluster members.

The distances between clustered switches can be more flexible. They can be in the same location or they can be located across a Layer 2 or Layer 3. But stacked switches are in the same layer and generally they are located in the same rack. Only virtual stackable switches can be placed in different locations.


After reviewing the discussion of switch stacking vs cascading vs clustering, you may find that the three technologies have the similarity that switches in a stack/cascade/cluster group need to be physically connected. Some are through common Ethernet ports, while some are through special stack ports. Cascading has the minimal requirements on the switch model, while both stacking and clustering require the switches to be stackable/cluster-capable, and are of the same model or at least from a single manufacturer. Stacking and cascading are based on hardware implementation while clustering is based on software implementation. The management of a stack is the most complete among the three.


Buy PoE Switch: 48-Port Switch vs 2 24-Port Switches

When we have about 30 PoE and non-PoE mixed connections in our network, the problem of buying a 48-port PoE switch vs. 2 x 24-port PoE switch always puzzles us. If we already have one 24-port PoE switch in use and we’re just adding more ports, we can choose to buy a single 16-24 ports PoE switch or a 16-24 ports Ethernet access switch to connect the increased devices. But as for a newly built network or 30 newly-deployed PoE devices, we have to balance the pros and cons of choosing one 48-port switch vs. 2 24-port switch.

48-Port Switch vs 2 24-Port Switch

PoE Connectivity: 48-Port Switch vs. 2 24-Port Switch Debate

In terms of the cost, usually one 48-port PoE switch will cost more than two 24-port PoE switches of the same model, but it does not mean always. For example, buying the 48-port PoE+ managed switch FS S1600-48T4S is lower than buying two 24-port PoE+ managed switches FS S1600-24T4F. If we have a tight budget and concerns cost saving most, the 1 x 48-port switch vs. 2 24-port switch debate can end here by buying the cheaper choice. Otherwise, we have more factors to consider.

Concerns of Installing 2 x 24 Port PoE Switch

In the options of one 48-port switch vs. 2 24 port switches, if we choose to do the job with two 24-port PoE switches, then we may have to undertake these shortcomings, unless they do not matter in our case. Firstly, two 24-port PoE switches take up more space than a 48-port PoE switch. A fixed-chassis 48-port PoE switch takes up a standard 1 RU space of the rack while 2 x 24-port PoE switch will use more space than that whether it is 1RU size or smaller. Secondly, if the 2 x 24-port PoE switches are not stacked then we have to do trunk between those two switches, which will eat up ports and give you only 46 ports available. At the same time it provides additional potential of bottleneck at the uplink port. Since the internal traffic on a switch is going to be gazillions of times faster than a 1G or even a 10G uplink between switches. But for a 48-port one, it will have less issues with bottleneck/congestion. The last concern is that two 24-port PoE switches are harder to manage than one 48-Port PoE switch, even when stacking the two.

Concerns of Installing 1 x 48 Port PoE Switch

When we decided to install only one 48-port switch versus 2 x 24-port switch, there are also some concerns in practice. The biggest issue is that we lose redundancy. If we have only one switch and it fails, we’re chained until we get the replacement, which could be over 24hrs away. But in a two switches’ scenario, if one switch fails at least half of our devices can still be up and running. Another thing we may lose is the separate placing of the 2 x 24-port switches. If we have a single rack to install them, then there’s no issue but if we want to place desktop switch for IP cameras and IP access points in different offices, we may not go with a 48-port PoE switch.

Suggestions for Selection

After the discussion about 48-port switch vs. 2 24-port switches, here are the conclusions we have. In terms of better performance, the a 48-port PoE switch is over 2 x 24-port switch. There’s less possibility of creating congestion between the two switches at the uplink ports. For easier management of the devices, it is also suggested to go with one single 48-port PoE switch rather than 2 x 24-ports. All ports on the 48-port PoE switch could communicate between them at wire speed. When we need the redundancy, we’d better go with 2 x 24-port PoE switch. If we want to avoid some problems brought by trunking and separate managing, we can choose stackable PoE switches or modular switch with two 24-port modules, which will provide large backplane and can be managed as a whole.


The concerns that we discuss in this post are general ones that we may have in choosing one 48-port switch vs. 2 24-port switch for PoE devices. The final decision should depend on our key purpose of buying them. The above factors are several things that we can take into account when we face the similar issue.

FAQs: How to Buy Best KVM Switch and Why

KVM (keyboard, video, mouse) switch is hardware device that can ease local or remote monitoring on multiple computers/servers via a single keyboard, video monitor and mouse console. Best KVM switch is not typically the most expensive but the one that has the exact features you need, not more or less. Before buying a KVM switch, ask yourself the following questions to figure out the best KVM switch that suits you.

How many computers/servers do I want to monitor?

This is the key factor in choosing the best KVM switch. It is like buying Christmas gifts for your kids, one gift for one kid and the number should not be less than the kid. Since the KVM switches are available with different port counts, you can choose the one the can connect all your computers/servers while having no ports wasted, unless you have near plan for adding more networking devices. A single KVM switch can usually connect directly 2 to 32 computers/servers. It should be noted that though multiple devices are connected to the KVM switch, you can only access one device at a time.

Which type of KVM switch do I need?

After a brief search you may find there are various types of KVM switches in the market. They are grouped into desktop KVM, rack-mount KVM and rack-mount console KVM. If you have no more than four computers to be controlled and have your own keyboard, monitor and mouse, the desktop model is the best KVM switch for you. Rack-mount KVM switch and rack-mount console KVM switch are commonly used for controlling multiple servers in data centers. They can save space of the rack by simplifying the one-server-one-keyboard to multi-servers-one-keyboard. A user can locally control all the servers in the rack. In addition, a rack-mount console KVM switch is equipped with a built-in keyboard, LCD (liquid crystal display)display and touchpad in a single console that collapses when not used, taking up only 1RU space.

Should I choose KVM switch with IP access or not?

Some KVM switch are just for local users while some KVM switch designed with network port allow users to control far-distance computers/servers. If it is just for controlling computers/servers locally, you can choose a KVN switch without IP access function.

Which port is for connecting the computer and which is for the monitor?

A KVM switch are designed with colorful KVM connection ports or/and copper RJ45 ports. You should choose the best KVM switch with the ports that fit your computer/server connectors.

The KVM switch has different ports for connecting keyboard and mouse, like PS/2, USB, Sun (DB13W3), Mac.

ports for keyboard and mouse

Also there are different ports for the video monitor like VGA, HDMI, DVI, display ports and ADC (Apple display connector). Rj45/DB9 serial port and network LAN port for local and remote control.

port for video monitor

To directly connect the computers/servers being involved, you can use KVM cable, Cat5/5e/6 Ethernet cable and SIU (server interface unit). Since KVM switches are designed with different port type for computers/servers.

computer server RJ45 & VGA ports

There are different forms of cable kit for connecting the computer/server to the KVM switch, some manufacturers make products that combine several cable types in one unit.

kvm cable Ehternet cable and SIU

What is the best KVM switch for controlling hundreds of devices?

A single KVM switch have limited number of ports to control devices. Some enterprise KVM switches have daisy chain port that allows several KVM switches to be cascaded together to control hundreds of computers/servers.

This article sums up some common questions that are asked when buying a best KVM switch for controlling multiple computers/servers. The primary question is based on your existing computer/server number and type. If you have more questions about buying or using KVM switches, welcome to discuss.


Common Power Cord Types: C13, C15, C19 and NEMA 5-15P

Electricity is one of the things that we rely on most in modern life and work, which is even more fundamental than the Internet. It has been utilized to serve human beings for centuries, and the technologies and standards in this filed have been developed and improved for better usage globally. The computer power cord C13 is a typical example of the achievements through power cord standardization. Do you know why use the letter C and the number 13 to name it? This post will explain the standards that power connectors comply to and the most commonly used power cord types.

International Power Cord Types: C13, C15 and C19

C13 power cord is specified by the power cord standard IEC 60320, which is recognized as an international standard by most countries in the world. The standard determines the electrical, mechanical, thermal requirements and safety operations of the specified power cord type. It also describes the shape, size and dimensions of the appliance to be connected to with the power cords. Among IEC 60320 standard power cord types, C13, C15, and C19 are the most commonly used connectors in both daily lives and data centers. Here are their specifications and appliances they apply to.

Connector Type Configuration Max. Current/Voltage Max. Pin Temp. (°C) Common Application
C13 C13 connector 10A/250V 70 C13 connectors commonly work with inlets on computers and devices that can be attached to computers.
C15 C13 connector 10A/250V 120 C15 connectors are for use in high temperature settings, such as electric kettles, computer networking closets, and PoE switches with high wattage power supplies.
C19 C13 connector 16A/250V 70 C19 connectors are common for devices that require higher current than which can be provided by C13 and C15 connectors. Typical applications are on enterprise-class servers, data center rack-mounted power distribution units (PDUs) and chassis switches.


IEC 60320 specifies female connector by odd number and the appliance inlet by even number one greater than the number assigned to the connector. Since C13, C15 and C19 are popular connectors, the popular power cord types with these connectors are C14 to C13 and C20 to C19. Other popular variants are C14 to C15 power cord and C20 to C15 power cord.

IEC 60320 power cord

NEMA 5-15P of NEMA Standard

Apart from the IEC 60320 standard, NEMA standard is also widely used in North American countries and other countries that adopt it. NEMA 5-15P plug is the most popular power cord type specified in NEMA standard. It has three-wire circuits (hot, neutral and ground), and is rated at 15 A at 250 V, although it usually carries 110 V. NEMA 5-15P (plug) to NEMA 5-15R (receptacle) is the most common power cord type in North American countries. As NEMA 5-15P is already accepted as an international plug standard, other typically used power cord types that adopt NEMA 5-15P plug include NEMA 5-15P to C13 and NEMA 5-15P to C15.

NEMA 5-15P power cord

Benefits of Universal Power Cords

Actually before the standards for power cords are made, most countries have used different wall-plugs and sockets. In the old days the problem arrived when a power cord manufacturer wanted to sell the products worldwide or when a traveler took his laptop from one country to another, because some countries run on 230V and others on 110V.

After the renouncement of the IEC 60320 standard, it has gradually become universal for electronic equipment. Modern computer power supplies don’t care which region you’re in and what voltage or frequency your electricity has or what types of wall-plugs you use, they transfer whatever AC you give them into the right sort of DC. In fact, if you go into a real server-room or data-center you will find that the wall-plugs of whatever region you are in are really non-existent, all the electronic devices connect directly with C13-C14 extension cords into the power supply of the server-room, usually redundantly and with some sort of emergency power in case of blackout being involved. The specifications of shape and size for different power cord types also keep people from accidentally matching incompatible plugs and inlets. So the danger of burning down the device or hurting people can be avoided.

Words in the End

Although different countries still have their own standards for power cords, the IEC 60320 standard and NEMA standard have been recognized globally. They have made it easy to use common power cord types all over the world. The ones that we frequently used in data centers and for computer power cord are best examples of their contribution, such as C14 to C13, C14 to C15, C20 to C19 and NEMA 5-15P to C13, etc.

Comparison of 48-Port PoE Switch Price and Functionality

When it comes to connecting a lot of VoIP phones and IP cameras, a 48-port PoE switch is great for powering them. Whether it is for home use or business use, a 48-port PoE switch can best solve the problems of installing these PoE network devices in places that has no power lines. Due to the high capacity and power supply feature, a 48-port PoE switch price is often higher than a standard 48-port Ethernet switch with no PoE. In this post, we will introduce some cheap 48-port PoE switches and do a comparison between them.

48-port PoE switch for VoIP phone IP camera

Comparison of Four 48-Port PoE Switches Prices and Functions

The four 48-port PoE switches that we’re going to discuss are UniFi US-48-500W, TP-Link T1600G-52PS, D-Link DGS-1210-52MP/ME and FS S1600-48T4S. They are inexpensive compared with most enterprise class 48-port PoE switches. Let’s have a look at these switches.

Difference Between the Four 48-Port PoE Switches

The table below gives some basic parameters of these four switches, including the port type, supported data rate, the maximum PoE power consumption, switching capacity and forwarding rate.

Switch Model UniFi US-48-500W TP-Link T1600G-52PS D-Link DGS-1210-52MP/ME FS S1600-48T4S
10/100/1000Mbps RJ45 Ports 48 48 48 48
Gigabit SFP Ports 2 4 4 0
SFP+ Ports 2 0 0 4
Max. PoE Power Consumption 500 W 470.4 W 479.5 W 600 W
Max. Power Per Port (PoE+) 30 W 30 W 30 W (ports 1-8) 30 W
Switching Capacity 140 Gbps 104 Gbps 104 Gbps 180 Gbps
Forwarding Rate 104.16 Mpps 77.4 Mpps 77.4 Mpps 130.94 Mpps
Price US$760.00 to US$1,230.90 US$481.99 to US$725.99 US$988.06 to US$1,028.01 US$689.00

The UniFi US-48-500W is a 48-port Layer 2 access switch. In addition to 48 Gigabit RJ45 ports, it has 2 fiber ports of Gigabit SFP and 2 fiber ports of 10G SFP+. It has a non-blocking throughout of 70 Gbps, which is sufficient for typical home use and most small business use. But compared with the other three 48-port PoE switches, it lacks some Layer 3 features. The other three are Layer 2+ switches that support static routing and access resolution protocol (ARP) inspecting, which are simple but efficient approaches in segmenting and securing the network.

Outwardly, the TP-Link T1600G-52PS and D-Link DGS-1210-52MP/ME are similar in many aspects. They both have 4 Gigabit SFP ports and their switch fabric capacity and forwarding rate are identical. However, the 48 RJ45 ports of T1600G-52PS are all IEEE 802.3at/af-compliant PoE+ ports, while the 48 RJ45 ports of DGS-1210-52MP/ME are not. Only ports 1-8 are PoE+ and the ports 9-48 are PoE. The price of T1600G-52PS is much lower than DGS-1210-52PS but the former one is released in 2015 while the latter one is 2017’s new model. Both T1600G-52PS and DGS-121052MP/ME has no 10G ability.

Obviously the switching capacity (or backplane bandwidth) and forwarding rate of the FS S1600-48T4S are the highest among these four switches. It has four 10G uplink ports, which allows large traffic from the access switch to the core switch and ensures high speed and precise transmission and recording without delay. Meanwhile, it supports the largest power to the device, which is suitable for connecting more PoE network devices. This 48-port PoE switch’s price is lower than two of the other switches.

Common Benefits and Features of the Four 48-Port PoE Switches

These four 48-port PoE switches’ prices are much lower than that of high-end PoE switches. They are all managed PoE switches equipped with 48 10/100/1000Mbps Rj45 ports of auto-sensing IEEE 802.3af (PoE), which provides a maximum per PoE port output power to each device of 15.4 W. They also support IEEE 802.3at (PoE+), which enhanced the max. per port power consumption to 30 W. All of them have been equipped with fiber uplink ports.

Another common feature is that these four 48-port PoE switches all support easy management. And the managing function is not limited to only one type. They all have an RJ45 console port or a serial port for managing through web-based graphical user interface (GUI, IPv4/IPv6) or command line interface (CLI).


This post has compared some 48-port PoE switches’ prices and functions. They are generally inexpensive and suitable for both home use and business use. The managing functions are simplified compared with high-end switches, in order to help better management of the network. If you want 10G uplink, UniFi US-48-500W or FS S1600-48T4S are recommended. Before purchasing a 48-port PoE switch, be sure to check the power requirement for your total PoE devices, the standard it complies to and the overall PoE budget of your installation.
