Troubleshooting
➐
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 authorized
reseller or authorized service provider, or use the electronic support services from
HP networking to get assistance. See the Customer Support/Warranty card for more
information.
➑
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, replace the fan tray. Contact your
authorized reseller or authorized service provider, or use the electronic support
services from HP networking to get assistance. See the Customer Support/Warranty
card for more information.
➒
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 networking Web site. See
page 5-1 for
details.
