Deploying 48-Port Gigabit PoE Managed Switch in Different Networks

Updated on December 21, 2021

Note: FS has removed the S1600-48T4S switches. For customers who are interested in FS S1600-48T4S switches, you can check FS 48-port PoE switches.

As we know, the power over Ethernet (PoE) technology is developed to meet the demand for connectivity to network devices like IP cameras, IP access points and voice over IP (VoIP) phones. PoE technology provides both data connection and power supply for these devices through only one Ethernet cable, which greatly simplifies the deployment of PoE devices. PoE network switch, such as 8-port Gigabit PoE switch and 24-port Gigabit PoE switch, are hardware devices used to connect these PoE appliances. Among them, 48-port Gigabit PoE managed switches are popularly used in LAN environments.

Featured Applications of 48-Port Gigabit PoE Switches

Due to its high port count and high capacity, 48-port PoE switches are able to provide connections to multiple PoE nodes, which makes it a favorite when used as an access layer switch. 48-port Gigabit PoE switches can sufficiently support applications in different networks, including that of small and midsize businesses (SMBs), public areas, schools and hospitals, etc. As for a 48-port PoE Layer 2+ switch with 10GbE ability, such as FS S1600-48T4S, it can be used as a core switch in some middle-size networks. The simplified management functions also facilitate in monitoring and configuring the switch.

Deployment of 48-Port Gigabit PoE Managed Switch

In this part we will discuss how to deploy the 48-port Gigabit PoE managed switch in different networks, both as an access layer switch and a core switch.

Deploying the 48-Port PoE Switch in Access Layer

When used in the access layer, the 48-port Gigabit PoE switch can support multiple PoE and non-PoE network devices. Assume that an SMB has two office buildings located 100 meters from each other, and each building has a server rack. The first office now has 20 VoIP phones, 10 IP cameras, 10 IP access points and 40 computers, while the second building has double the number of devices. Here we will need not only 48-port PoE switches but also some Ethernet switches in the access layer.

Deploying the 48-Port PoE Switch as a Core Switch

For small and midsize networks, the 48-port Gigabit PoE L2+ switch can also be deployed in the core area. By implementing link aggregation, we can establish an aggregated high bandwidth link between the core switch and the access switch, so that the abundant end clients being connected by different access switches can communicate without blocking. For a 48-port Gigabit PoE switch with 10G fiber ports, it can not only do 4x10G aggregation between the core switch and the access switch with 10G fiber uplink ports, but also do 4x1000Mbps aggregation between the core switch and the Gigabit access switch.

Management Functions of 48-Port Gigabit PoE Switch

The management functions of the 48-port Gigabit PoE switch FS S1600-48T4S enable easy configuration of the PoE ports. Managing can be done through Web interface, Command Line Interface, Telnet, SSH, SNMP, etc. Here we will introduce how to configure some parameters of the 48-port PoE switch in details.

Alter Between PoE and PoE+

Besides PoE, the FS S1600-48T4S also supports enhanced PoE (PoE+). So the maximum per port PoE consumption is increased from 15.4W to 30W, which can be configured on demand of course.

Command Purpose
Switch(config)# interface {FastEthernet | GigabitEthernet} slot/port Select the interface to configure.
Switch(config-if)# poe mode plus Enable PoE+ mode, Max. 30W power consumption per PoE port.
Switch(config-if)# poe mode standard Enable PoE standard mode, Max. 15.4W power consumption per PoE port.
Switch(config-if)# end Exist configuration mode.

For example, if we want to set the port 1 of this S1600-48T4S switch as PoE+ mode, we can perform this task:

S1600-48T4S-SW1(config)# interface GigabitEthernet 1/1 S1600-48T4S-SW1(config-if)# poe mode plus S1600-48T4S-SW1(config-if)# end

Turn off the PoE

If the device connected to the 48-port PoE switch is non-PoE and we want to shut down the electrical power on this interface, the command is:

Command Purpose
Switch(config)# no poe mode Shut down the power supply on the selected port.

For example, if ports 1~5 of S1600-48T4S are connected to PCs, the following command can turn off the power supply to these PCs but just keep the data transfer function.

S1600-48T4S-SW1(config)# interface GigabitEthernet 1/1~5 S1600-48T4S-SW1(config-if)# no poe mode S1600-48T4S-SW1(config-if)# end

Check the Operational Status of PoE Interface

When we need to know the operational information of the PoE interface, we can use the command “Switch# show poe” to get it. For example:

S1600-48T4S-SW1# show poe

Then we can know the power supply from the interface and the power consumption of the device.


48-port Gigabit PoE managed switches are preferred in LAN applications for both access layer and core layer due to its high functionality and simplified management features. The deployment examples of the 48-port Gigabit PoE managed switch FS S1600-48T4S can prove the versatility of 48-port PoE switches. And the configuration of PoE ports is also as easy as can be seen on the above parts.
