The GS1920-24HP, and GS1920-48HP come with a Power-over-Ethernet (PoE) feature. The GS1920-24HP,
and GS1920-48HP support the IEEE 802.3at High Power over Ethernet (PoE) standard and IEEE 802.3af PoE
standard.
Key feature differences between Switch models are as follows. Other features are common to all
models
The following table describes the PoE features of the Switch by model.
This section shows a few examples of using the Switch in various network environments.
1.1.1 Backbone Application
The Switch is an ideal solution for small networks where rapid growth can be expected in the near future.
The Switch can be used standalone for a group of heavy traffic users. You can connect computers and
servers directly to the Switch’s port or connect other switches to the Switch.
In this example, all computers can share high-speed applications on the server. To expand the network,
simply add more networking devices such as switches, routers, computers, print servers etc.
