Diagnostic Tips:

Tip

Problem

Solution

➊

The switch is not
plugged into an
active AC power
source, or the
switch’s power
supply may have
failed.

1. Verify that the power cord is plugged into an active power source and to the switch.

Make sure 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 that 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.

➋

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 LAN dealer, or use the electronic support services from HP to get
assistance. See the Customer Support/Warranty card for more information.

➌

The switch has
experienced a
software failure
during self test.

1. Try resetting the switch by pressing the Reset button on the front of the switch, or by

power cycling the switch.

2. If the fault indication reoccurs, attach a console to the switch (as indicated in chapter

2) and configure it to operate at 9600 baud. Then, reset the switch. Messages should
appear on the console screen and in the console log identifying the error condition.
You can view the console log at that point by selecting it from the console Main Menu.

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.

➍

The module
installed in the
slot is not
installed
properly, has
experienced a
self test fault, or
has become
partly removed
during switch
operation.

The module is tested whenever the switch is powered on, or reset (through the Reset
button on the switch, or the Reboot or Reset options in the console or web browser
interface), and when it is hot swapped (installed when the switch is powered on).
Under this error condition, the following events also occur:
• All the LEDs on the module stay on until the error is resolved.
• The switch software, including console and web browser access will not be opera-

tional for approximately one minute from the time the module gets into this condition.

Try rebooting the switch again. If that does not resolve the problem, try reinstalling the
module. You can do this without having to power down the switch. When the module is
reinstalled, it will be retested automatically. Make sure to screw in the retaining screws
so that the module cannot be inadvertently pulled out by pulling on the network cables.
If the fault indication reoccurs, the module may have failed. Remove the module from the
switch and replace it with another module, or cover the slot with the cover plate. 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.
