Troubleshooting
C
One or more of the
switch cooling fans
may have failed.
Try disconnecting power from the switch and wait a few moments. Then reconnect
the power to the switch and check the LEDs again. If the error indication reoccurs,
one or more of the fans have failed. The switch has multiple fans and may continue
to operate OK under this condition if the ambient temperature does not exceed
normal room temperature, but for best operation, the switch should be replaced.
Contact your HP-authorized LAN dealer, or use the electronic support services from
HP to get assistance. See the Customer Support/Warranty card for more
information.
D
A fault condition
has been detected
on the power
supply installed in
the slot
corresponding to
the flashing
number.
Because the Power LED is on, the switch is receiving power from one power supply,
but the power supply in the slot corresponding to the flashing number may be
unplugged from an active AC power source, or may be faulty.
• Verify the power cord for the power supply whose number is flashing is plugged
into an active power source and to the switch. Ensure these connections are
snug.
• Disconnect the AC power cord from the power supply in the slot corresponding
to the flashing number, then try removing and reinstalling the power supply.
Caution: Ensure the AC power cord is disconnected from the supply before removing
and reinstalling the supply.
Reconnect the power supply to the AC power source. If the error indication reoccurs
after the supply is reinstalled, the power supply may be faulty. Call your HP-
authorized LAN dealer, or use the electronic support services from HP to get
assistance. See the Customer Support/Warranty card for more information.
E
The switch has
experienced a
backplane failure
during self test.
The failure may be just in the communications with a single module slot, or it might
be more significant. Start a console session with the switch, and at the CLI prompt
issue the command show logging. In the event log that is displayed, there will be
messages that describe the extent of the problem. If the problem is with individual
slots, the remainder of the switch slots will be fully operational and can be used until
you get a chance to replace the switch.
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 Customer
Support/Warranty card for more information.
F
The network port
for which the Link
LED is flashing has
experienced a self
test or initialization
failure.
When the switch is powered on, each network port is tested. If the port self test fails,
the individual port is not usable, but the rest of the ports on the chassis, which have
passed their self test, will continue to operate normally.
To verify the port has failed, try power-cycling the switch. If the port fault indication
reoccurs, and the port is one of the fixed ports on the chassis, you will have to
replace the switch. In the meantime, all the other fixed ports on the chassis will
operate normally.
