Troubleshooting
Diagnosing with the LEDs
A switch hardware
failure has occurred.
All the LEDs will stay
on indefinitely.
Try power cycling the switch. If the fault indication reoccurs, the switch may have
failed. Call your HP authorized network reseller, or use the electronic support
services from HP to get assistance.
The network port for
which the Link LED is
blinking has
experienced a self test
or initialization failure.
Try power cycling the switch. If the fault indication reoccurs, the switch port may
have failed. To confirm, try a different port that appears to be good. Call your HP
authorized network reseller, or use the electronic support services from HP to get
assistance.
If the port is an SFP (mini-GBIC), verify that it is one of the SFPs supported by the
switch. Unsupported SFPs will be identified with this fault condition. The supported
SFPs are listed in Chapter 1, “Switch Overview” on page 1-3. The SFPs are also
tested when they are “hot-swapped”— installed or changed while the switch is
powered on.
To verify that the port has failed, try removing and reinstalling the SFP without having
to power off the switch. If the port fault indication reoccurs, you will have to replace
the SFP.
The network
connection is not
working properly.
Try the following procedures:
For the indicated port, verify that both ends of the cabling, at the switch and the
connected device, are secure.
Verify the connected device and switch are both powered
on
and operating
correctly.
Verify that the connected devices comply with the appropriate IEEE 802.3 stan-
dard, including transmission of the Link signal.
If the other procedures do not resolve the problem, try using a different port or
a different cable.
