Troubleshooting

3-6

Power LED

is OFF

If there is no power to the switch, it cannot function.

A Power LED that is OFF may indicate:

A loose power cord.

Power supply failure, malfunction or loss of power to the

power supply.

A power supply voltage is below acceptable levels.

A high switch temperature due to fan failure or ambient

temperature extreme.

Perform the following steps in sequence; you need not proceed to

the next step if the problem is resolved:

1. Secure the power cord to the power source and check the Power LED

to see if it is ON.

2. Ensure that the voltage is within the required levels in your region.

3. Log on to Omega and run Diagnostics if you can (

System

administration>Diagnostics

) and record any failures.

4. Contact Allied Telesyn’s technical support and report the results of

the tests.
