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

1.Verify 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 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 booklet for more information.

➎The network port for which the LED is flashing has experienced a self test or initialization failure.

Try power cycling the switch. If the fault indication reoccurs, the switch port 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 booklet for more information.

If the port is a mini-GBIC, verify that it is one of the mini-GBICs supported by the switch. Unsupported mini-GBICs will be identified with this fault condition. The supported mini-GBICs are listed in Chapter 2, “Installing the Switch” on page 2-17. The mini-GBICs are also tested when they are “hot-swapped”—installed or changed while the switch is powered on.

To verify the port has failed, remove and reinstall the mini-GBIC without powering off the switch. If the port fault indication reoccurs, you will have to replace the mini-GBIC. Check the event log to see why the mini-GBIC failed.
