Installing the Switch
Installation Procedures
LED Behavior
During the self test:
• Initially, all the switch and port LEDs are on. Most of the LEDs go off
and then may come on again during phases of the self test.
• For the duration of the self test, the Test LED stays on.
When the self test completes successfully:
•The Power, PoE and Fan (Switch 2520G-24-PoE only) LEDs remain on.
•The Fault, Locator and Test LEDs stay off.
•The Act LED remains on indicating the default port LED mode.
• The port LEDs on the front of the switch go into their normal opera-
tional mode:
– If the ports are connected to active network devices, the Link
LEDs stay on and the Mode LEDs behave according to the mode
selected. In the default mode (Act), the Mode LEDs should be
blinking indicating port activity.
– If the ports are not connected to active network devices, the Link
and Mode LEDs will stay off.
If the LED display is different than what is described above, especially if
the Fault and Test LEDs stay on for more than 60 seconds or they start
flashing, the self test has not completed correctly. Refer to chapter 4,
“Troubleshooting” for diagnostic help.
3. Mount the Switch
After the switch passes self test, it is ready to be mounted in a stable location.
The switch can be mounted in these ways:
■ in a rack or cabinet
■ on a horizontal surface
■ on a wall
Rack or Cabinet Mounting
The Switch 2520G-24-PoE is designed to be mounted in any EIA-standard 19-
inch telco rack or communication equipment cabinet. The Switch 2520G-8-
PoE can also be rack mounted using the optional bracket kit, 5070-6570 (not
included).
Note that the mounting brackets have multiple mounting holes and can be
rotated allowing for a wide variety of mounting options. Secure the rack in
accordance with the manufacture’s safety guidelines.
