9. Reconnect the interface cable.
10. Check the Bypass and Fault LEDs for the new SFP module.
11. Based on the status of the Bypass and Fault LEDs, choose one of the
following steps:
v Bypass LED or Fault LED is on - Reinstall the SFP module and cables,
and verify that the SFP module and cables are securely connected. Use the
fibre channel loopback and the LC-LC connector to perform path diagnostics
to ensure that the FC cable is good and the SFP on the other end of the
fibre channel connection is working properly. When finished, go to step 12.
v Bypass LED and Fault LED are off - Go to step 12.
12. Is the problem corrected?
v Yes - Go to step 13.
v No - Contact IBM Support.
13. Complete any remaining Recovery Guru procedures, if needed.
14. Use the DS4000 Storage Manager Subsystem Management window to check
the status the status of all components in the storage subsystem.
15. Remove the antistatic protection.

v Yes - Select the Recovery Guru toolbar button in the Subsystem
Management window, and complete the recovery procedure. If the problem
persists, contact IBM Support.
v No - Go to step 17.
17. Use the DS4000 Storage Manager client software to print a new storage
subsystem profile.
