10. Check the Bypass and Needs Attention LEDs for the new SFP module.
Based on the status of the Bypass and Needs Attention LEDs, choose one of
the following steps:
v
Bypass LED or Needs Attention LED is illuminated – The SFP module and
cables might be installed incorrectly, or the cable might not be securely
connected. Reinstall the SFP module and cable, check the cable
connection, and then go to step 11.
v
Bypass LED and Needs Attention LED are off – Go to step 12.
11. Is the problem corrected?
v
Yes – Go to step 12.
v
No – Contact your IBM support representative.
12. Remove the antistatic protection.
13. Use the DS Storage Manager Subsystem Management window to check the
status of all components in the storage subsystem.
14. Do any storage subsystems have a Needs Attention (Needs Attention) status?
v
Yes – Select the Recovery Guru toolbar button in the Subsystem
Management window and complete the recovery procedure. If the problem
persists, contact your IBM service representative.
v
No – Go to step 15.
15. Use the DS Storage Manager client software to print a new storage subsystem
profile.
Installing SFPs and fiber-optic cables
Each RAID controller unit has single-ported host channels and dual-ported drive
channels. SFPs are inserted into the ports, and then fibre-channel cables are
connected to the SFPs.
For information on installing SFPs and fiber-optic cables, see “Working with SFPs
and fiber-optic cables” on page 47.
Removing and disposing of the lithium batteries
When you disassemble the storage subsystem for disposal, use the information in
this section to locate, remove, and dispose of the lithium batteries that are on the
system boards in Controller A and Controller B.
