Troubleshooting
➐
The network port
for which the Link
LED is blinking has
experienced a self
test or initialization
failure.
During the module self test, described in tip number 4 earlier in this table, each
network port is also tested. If the port self test fails, the individual port is not usable,
but the rest of the ports on the module, which have passed their self test, will
continue to operate normally.
If the port is a transceiver, verify it is one of the transceivers supported by the
mini-GBIC zl Module. Unsupported transceivers will be identified with this fault
condition. The supported transceivers are listed in the module Installation Guide.
The transceivers are also tested when they are “hot-swapped”--installed or
changed after the mini-GBIC zl Module is installed and receiving power from the
switch.
To verify the port has failed, try removing and reinstalling the module, as described
in tip number 4. For the transceivers, you can just remove and reinstall the
transceiver without having to remove the module. If the port fault indication
reoccurs, and you need to be able to use the port, you will have to replace the
transceiver or the module. In the mean time, all the other module ports will operate
normally.
➑
A fault condition
has been detected
on the power
supply installed in
the slot
corresponding to
the blinking
number.
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 dealer, or use the electronic support services from HP networking to get
assistance. See the Customer Support/Warranty card for more information.
➒
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 has 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 fan tray should be replaced.
Contact your HP authorized dealer, or use the electronic support services from HP
networking to get assistance. See the Customer Support/Warranty card for more
information.
➓
The network port
for which the Link
LED is blinking has
been disabled
because port
security has been
configured on the
switch and a
security violation
has been detected
on the port.
For the Port Security feature, you can configure the switch so that whenever a
security violation is detected on a port, the switch will disable the port. When a port
is disabled by this feature, the port Link LED will be continuously flashed at the fast
rate of 0.8 seconds per cycle. The blinking continues until you clear the security
violation through the switch console. In the console, you can view the identity of the
connected device that committed the security violation.
Once the security violation is cleared, you must re-enable the port through the
console.
For more information on the Port Security feature, see the Management and
Configuration Guide which is on the HP Web site.
