Installing the switch
Installation procedure
2. Check the LEDs on the switch as described below.
Self Test LED Behavior:
During the self test:
• Initially, the Power, Fault, Locator, and all port LEDs turn on.
• After several seconds, the Power, Fault and Locator LEDs remain on, and
the port LEDs turn off. Then, each port Link LED is sequentially turned on,
and then turned off.
• The Fault and Locator LEDs turn off when the self test completes.
When the self test completes successfully:
• The Power LED remains on.
• The Fault, and Locator LEDs stay off.
• The port LEDs on the front of the switch go into their normal operational
mode:
– If the ports are connected to active network devices, the Link/Act LEDs
stay on or blink to indicate port activity. The Spd LEDs turn on for 1000
Mb/s links, blink for 100 Mb/s links, or remains off for 10 Mb/s links.
– If the ports are not connected to active network devices, the Link/Act
and Spd LEDs remains off.
If the LED display is different than what is described above, the self test
has not
completed correctly. For diagnostic help, see Chapter 4, "Troubleshooting".
