Checking the Module LEDs

Checking the Module LEDs
The following table lists Switch Management Module LED behavior showing
error conditions.
Table 7-1.
LED
Status
Description
Self Test
ON
The module is being self tested as a result of being powered on or because of a reset. If it
stays ON for a prolonged period of time (more than 30 seconds), the module has experienced
a hardware failure. See the instructions for the ON condition under the Fault LED below.
Flashing
This should only occur if the Fault LED is also flashing, and indicates that the module has failed
its firmware self test. See the instructions for the Flashing condition under the Fault LED below.
Try resetting the switch and module by pressing the Reset button on the module.
If the fault condition persists, attach a PC to the switch and run the console interface; the log
file should indicate the error condition. See Note below.
Fault
ON
The module is being self tested as a result of being powered on or because of a reset. If it
stays ON for a prolonged period of time (more than 30 seconds), the module has experienced
a hardware failure.
Try resetting the switch and module by pressing the Reset button on the module.
If the failure persists, it may be due to incorrect module installation. Remove power from the
switch and try reinstalling the module. This condition may also be caused by an incorrectly
installed SIMM on the module. While the module is removed, verify that the SIMM is correctly
installed.
Apply power to the switch again. If the fault condition persists, the module may have to be
replaced.
If none of these procedures resolves the condition, the module may be faulty and would need
to be replaced. Contact your HP-authorized LAN dealer for assistance.
Flashing
Indicates that the module has failed its firmware self test.
Try resetting the switch and module by pressing the Reset button on the module.
If the fault condition persists, attach a PC to the switch and run the console interface; the log
file should indicate the error condition. See Note below.
Note:
If the Self Test and Fault LEDs are flashing (not constantly on), you should be able to use the switch console to read
the switch event log to identify the problem. If necessary to resolve the problem, contact your HP-authorized LAN
dealer, or use the electronic support services from HP to get assistance. See the perforated card at the front of this
manual for more information.
