Diagnosing with the LEDs

Number

Problem

Solution

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

During the module self test, described in tip number 4 earlier in this table, each network port is also tested. If the port self test fails, the individual port is not usable, but the rest of the ports on the module, which have passed their self test, will continue to operate normally.

If the port is a mini-GBIC, verify it is one of the mini-GBICs supported by the mini-GBIC zl Module. Unsupported mini-GBICs will be identified with this fault condition. The supported mini-GBICs are listed in the module Installation Guide. The mini-GBICs are also tested when they are “hot-swapped”--installed or changed after the mini-GBIC zl Module is installed and receiving power from the switch.

To verify the port has failed, try removing and reinstalling the module, as described in tip number 4. For the mini-GBICs, you can just remove and reinstall the mini-GBIC without having to remove the module. If the port fault indication reoccurs, and you need to be able to use the port, you will have to replace the mini-GBIC or the module. In the mean time, all the other module ports will operate normally.

Troubleshooting

A fault condition has been detected on the power supply installed in the slot corresponding to the blinking number.

Try removing and reinstalling the power supply.

Caution: Ensure the AC power cord is disconnected from the supply before removing and reinstalling the supply.

Reconnect the power supply to the AC power source. If the error indication reoccurs after the supply is reinstalled, the power supply may be faulty. Call your ProCurve authorized dealer, or use the electronic support services from ProCurve Networking to get assistance. See the Customer Support/Warranty card for more information.

One or more of the switch cooling fans may have failed.

Try disconnecting power from the switch and wait a few moments. Then reconnect the power to the switch and check the LEDs again. If the error indication reoccurs, one or more of the fans has failed. The switch has multiple fans and may continue to operate OK under this condition if the ambient temperature does not exceed normal room temperature, but for best operation, the fan tray should be replaced. Contact your ProCurve authorized dealer, or use the electronic support services from ProCurve Networking to get assistance. See the Customer Support/Warranty card for more information.

The network port for which the Link LED is blinking has been disabled because port security has been configured on the switch and a security violation has been detected on the port.

For the Port Security feature, you can configure the switch so that whenever a security violation is detected on a port, the switch will disable the port. When a port is disabled by this feature, the port Link LED will be continuously flashed at the fast rate of 0.8 seconds per cycle. The blinking continues until you clear the security violation through the switch console. In the console, you can view the identity of the connected device that committed the security violation.

Once the security violation is cleared, you must re-enable the port through the console.

For more information on the Port Security feature, see the Management and Configuration Guide which is on the ProCurve Web site. See page 5-1for details.
