If a Logged-In LED is flashing, do the following:

1.Inspect the cable connecting the port to another switch or to a device. Is the cable connected and in good operating condition?

■Yes - Continue.

■No - Make necessary corrections or replace the cable.

2.Inspect the switch or device to which the port is connected. Is the switch or device operating properly?

■Yes - Continue.

■No - Make necessary corrections. If the problem remains, continue.

3.Replace the SFP. Does this correct the problem?

■Yes - Diagnosis complete.

■No - Continue.

4.Inspect the switches in the fabric for domain ID, timeout value, or conflicting zone name problems. Do any of these conditions exist?

■Yes - Reconfigure the switches as needed to eliminate the problem. Refer to the SANbox2 Switch Management User’s Guide for information about how to change domain IDs, timeout values, and edit zoning.

■No - Contact your authorized maintenance provider.
