Tip
Number Problem
➐
The network port
for which the Link
LED is blinking has
experienced a self
test or initialization
failure.
➑
A fault condition
has been detected
on the power
supply installed in
the slot
corresponding to
the blinking
number.
➒
One or more of the
switch cooling fans
may have failed.
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.
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
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
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.
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 networking
to get assistance. See the Customer Support/Warranty card for more information.
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 switch should be replaced.
Contact your HP authorized LAN dealer, or use the electronic support services from
HP networking to get assistance. See the Customer Support/Warranty card for more
information.
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 networking Web site. See
details.
