POST Diagnostics

ALogged-In LED error indication is often the result of E_Port isolation. An isolated E_Port is indicated by a red link in the topology display. Table 5-1describes the causes and remedies for E_Port isolation conditions. Refer to the SANbox2-8c/16 Switch Management User’s Guide for information about how to change domain IDs, timeout values, and edit zoning.

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 SANbox2-8c/16 Switch Management User’s Guide for information about how to change domain IDs, timeout values, and zoning.

No - Contact your authorized maintenance provider.
