Problem Solution
A
The power supplies
installed in the
switch are not
plugged into active
AC power sources,
or the power supply
may have failed.
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.
B
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.
