Diagnostic Tips:
Tip
Number
Problem
The power supplies
installed in the
switch are not
plugged into active
AC power sources,
or the power supply
may have failed.
A switch hardware
failure has
occurred. All the
LEDs will stay on
indefinitely.
The switch has
experienced a
backplane failure
during self test.
The module
installed in the slot
that corresponds to
the letter that is
flashing is an
invalid module.
1. Verify the power cord is plugged into an active power source and to the switch.
Ensure these connections are snug.
2. Try power cycling the switch by unplugging and plugging the power cord back in.
3. If the Power LED is still not on, verify the AC power source works by plugging
another device into the outlet. Or try plugging the switch into a different outlet or
try a different power cord.
If the power source and power cord are OK and this condition persists, the switch
power supply may have failed. Call your HP-authorized LAN dealer, or use the
electronic support services from HP to get assistance. See the Customer Support/
Warranty card for more information.
Try power cycling the switch. If the fault indication reoccurs, the switch may have
failed. Call your HP-authorized LAN dealer, or use the electronic support services
from HP to get assistance. See the Customer Support/Warranty card for more
information.
The failure may be just in the communications with a single module slot, or it might
be more significant. Start a console session with the switch, and at the CLI prompt
issue the command show logging. In the event log that is displayed, there will be
messages that describe the extent of the problem. If the problem is with individual
slots, the remainder of the switch slots will be fully operational and can be used until
you get a chance to replace the switch.
If necessary to resolve the problem, contact your HP-authorized LAN dealer, or use
the electronic support services from HP to get assistance. See the Customer
Support/Warranty card for more information.
The fact that the Link and Mode LEDs never are lit on the module indicates that it is
a ProCurve Switch gl or vl module and should not be used in your xl switch.
Ensure you have installed an xl module in the slot. ProCurve gl and vl
modules will fit in the slot, but they are not compatible with your ProCurve
xl switch. Check to ensure the module has a magenta "xl module" symbol
on it.
Remove the module from the switch and replace it with an xl module, or recover the
slot with the cover plate. You can remove and replace the module without having to
power down the switch. Call your HP-authorized LAN dealer, or use the electronic
support services from HP to get information on supported Switch xl modules. The
modules that are available as of the printing of this manual are listed on
