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