Tip Problem Solution

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

Troubleshooting

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

If the Mdl Status LED is blinking, the affected port is on the cl Module.

Try power cycling the switch. If the fault indication reoccurs, the switch port may have failed. Call your ProCurve authorized LAN dealer, or use the electronic support services from ProCurve to get assistance. See the Customer Support/Warranty booklet for more information.

If the port is a transceiver, verify it is one of the transceivers supported by the switch. Unsupported transceivers will be identified with this fault condition. The supported transceivers are listed in the ProCurve Switch cl Modules Installation Guide.

To verify the port has failed, try removing and reinstalling the transceiver without having to power off the switch. If the port fault indication reoccurs, you will have to replace the transceiver.
