Chapter 1: Introduction
Welcome
24-Port 10/100 + 2-Port Gigabit Switch with Webview and Power over Ethernet
Chapter 1: Introduction
Welcome
Thank you for choosing the 24-port 10/100 + 2-Port Gigabit Switch with WebView and Power over Ethernet. This
Switch will allow you to network better than ever.
This new Linksys rackmount Switch delivers non-blocking, wire speed switching for your 10 and 100 megabit
network clients, plus multiple options for connecting to your network backbone. Twenty-four 10/100 ports wire
up your workstations, while the two integrated 10/100/1000BaseTX ports connect to other switches and the
backbone at Gigabit speeds. And the mini-GBIC ports allow future expansion through alternate transmission
media like optical fiber.
All the 10/100 ports on this Switch support IEEE 802.3af standard (802.3af) Power-over-Ethernet (PoE)
capabilities. Each port can detect connected 802.3af-compliant network devices, such as IP phones or wireless
access points, and automatically supply the required DC power.
The Switch can provide DC power to a wide range of connected devices, eliminating the need for an additional
power source and cutting down on the amount of cables attached to each device. Once configured to supply
power, an automatic detection process is initialized by the Switch that is authenticated by a PoE signature from
the connected device. Detection and authentication prevent damage to non-PoE devices.
The Switch features WebView monitoring and configuration via your web browser, making it easy to manage the
128 VLANs and up to 4 lagging groups. Or if you prefer, you can use the integrated console port to configure the
Switch. The non-blocking, wire-speed switching forwards packets as fast as your network can deliver them.
All ports have automatic MDI/MDI-X crossover detection. Each port independently and automatically negotiates
for best speed and whether to run in half- or full-duplex mode. Head-of-line blocking prevention keeps your high-
speed clients from bogging down in lower-speed traffic and fast store-and-forward switching prevents damaged
packets from being passed on into the network.
Use the instructions in this User Guide to help you connect the Switch, set it up, and configure it to bridge your
different networks. These instructions should be all you need to get the most out of the 24-port 10/100 + 2-Port
Gigabit Switch with WebView and Power over Ethernet.
