2. Check the LEDs on the switch as described below.
Power, Fault,
Locator LEDs
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
