Power Supply Over Temperature LED is Illuminated

The power supply Over Temperature LED illuminates to indicate that the power supply is overheating. If the power supply Over Temperature LED illuminates, do the following:

1.Inspect the chassis fans. Are the intake openings clear? Are both fans operating and producing air flow?

Yes - Continue.

No - Remove any debris from fan intakes if necessary. Replace any fan that is not operating. Refer to Section 6 Removal/Replacement. If the condition remains, continue.

2.Consider the ambient air temperature near the switch and clearance around the switch. Make necessary corrections. If the condition remains, continue.

3.Replace the power supply. Refer to Section 6 Removal/Replacement. If the condition remains, contact your authorized maintenance provider.

Recovering a Switch

A switch can become inoperable or unmanageable for the following reasons:

Firmware becomes corrupt

IP address is lost

Switch configuration becomes corrupt

Forgotten password

In these specific cases, you can recover the switch using maintenance mode. Maintenance mode temporarily returns the switch IP address to 10.0.0.1 and provides opportunities to do the following:

Unpack a firmware image file

Restore the network configuration parameters to the default values

Remove all user accounts and restore the Admin account name password to the default.

Copy the log file

Restore factory defaults for all but user accounts and zoning

Restore all switch configuration parameters to the factory default values

Reset the switch

Display firmware versions stored on the switch

Select the firmware image to activate
