Power Fault RPS Port
OFF * * * Check the power cord and power source. If they are OK, the switch
may have to be replaced. Contact your HP-authorized LAN dealer
or HP representative for assistance.
ON OFF * OFF when
cable first
connected
Link beat has not been detected on the port. Check that the cabling
on the indicated port is connected properly. Faulty or improperly
wired cables are common; try a different cable.
For the 100 Mbit/s ports, verify that you are using category 5, or
better, UTP or the appropriate fiber-optic cable. Also, the you have
not connected a 10 Mbit/s device to the port.
If you have a Management Module in the switch, use HP
AdvanceStack Assistant or the switch console to determine the
state of the port:
- Determine if the port was disabled. Re-enable if desired.
ON Flashing * Flashing This could only occur with the port LED for the 100 Mbit/s transceiver
port, and only when a 100VG transceiver module has been installed
in the slot. Only 100Base-TX and 100Base-FX transceivers should
be installed in the transceiver slot.
ON Flashing Flashing * The Redundant Power Supply (RPS) has experienced a fault and is
now using its backup power capabilities. See the documentation
provided with the RPS for troubleshooting.
OFF * OFF and
you are
using an
RPS
* The switch is not receiving power from the Redundant Power Supply
(RPS). If you have an RPS connected, check the status of the RPS
and check the cable and power connections on both the switch and
the RPS.
ON Flashing * Variable A fault has been detected during self test in a switch component that
controls network communications through multiple switch ports.
Try power cycling the switch. If the error persists, the switch may
have to be replaced. Contact your HP-authorized LAN dealer or HP
representative for assistance.
ON ON for a
pro-
longed
period
* Variable, all
may be ON
A switch hardware failure was detected during self-test. Self-test
does not complete so the LEDs will stay on longer than 60 seconds.
Power cycle the switch. If this condition persists, the switch may
have to be replaced. Contact your HP-authorized LAN dealer or HP
representative for assistance.
* This LED is not important for the diagnosis.
The flashing behavior is a regular pulse once every 1.6 seconds, approximately.
