Troubleshooting a Network or Fibre Channel Port Connection

Troubleshooting a Connection to a Fibre Channel Port

A bad connection to a Fibre Channel port (FC 1 through FC 8) is indicated by the LOG LED flashing twice per second. If the LOG LED is flashing twice per second, follow these steps to help isolate the problem:

Step 1 Make sure that the Domain ID of the SN 5428-2 is configured properly. For information about configuring the Domain ID, see the Cisco SN 5428-2 Storage Router Software Configuration Guide. If the Domain ID is configured properly, continue to the next step.

Note When a connection problem is resolved, the LOG LED will turn on after a brief logging-in period that is indicated by the LOG LED flashing once per second.

Step 2 Check to make sure that the cable is connected properly and in good operating condition.

•Disconnect and connect both ends of the cable. If the LOG LED turns on, then the cable was not connected properly.

•If the LOG LED remains off, replace the cable. If the LOG LED turns on, then the cable was defective.

•If the LOG LED remains off, the cable is most likely not the problem. Continue to the next step.

Step 3 Check the device or switch to which the port is connected.

•If the device or switch is operating properly, continue to the next step.

•If the device or switch is not operating properly, then correct the problem. If the LOG LED turns on, then the problem was with the device or switch.

•If the LOG LED remains off, continue to the next step.

Step 4 Replace the SFP module.

•If the LOG LED turns on, the problem was the SFP module.

•If the LOG LED remains off, contact a customer service representative for instructions.
