See the following tables to diagnose the LED error indicators in the previous

table.

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
