v Now, the battery age clock is reset to 0.
12.
Remove the antistatic protection.
13. Install the front bezel by aligning the pins on the storage subsystem chassis
with the spring-steel retainers on the cover and then press the cover toward
the chassis until the pins snap into place.
14. Use the Subsystem Management window to check the status of all
components in the storage subsystem.
15. Do any storage subsystems have a fault (Needs Attention) status?
v Yes – Select the Recovery Guru toolbar button in the DS4000 Storage
Manager Subsystem Management window, and complete the recovery
procedure. If the problem persists, contact your IBM service representative.
v No – Go to step 16.
16.
Use the DS4000 Storage Manager client software to print a new storage
subsystem profile.
Note: Note that it might take from 15 minutes to a few hours for a new battery
to become fully charged. The DS4000 Storage Manager client will show
the battery as charging until it is fully charged. Controller caching is
automatically disabled until the new battery becomes fully charged.
17. After 24 hours, check the Needs Attention and Battery LEDs to ensure that the
battery is working properly.
If the replacement battery indicates a fault, contact your IBM support
representative.
Replacing an SFP module
Use the following procedure to replace an SFP module in a controller. The SFP
module shown in this procedure might look different from those you are using, but
the difference does not affect SFP module performance.
Electrostatic discharge can damage sensitive components. To prevent electrostatic
discharge damage to the storage subsystem, use proper antistatic protection when
handling the DS4800 components.
Attention: Removing an SFP module that has not failed can cause data loss. To
prevent data loss, remove only the SFP module that has a Bypass LED on or that
displays a failed status in the DS4000 Storage Manager client software.
1. Use the DS4000 Storage Manager client software to print a new storage
subsystem profile.
2. Locate the storage subsystem that has the failed SFP module by checking the
Overall DS4800 Configuration Needs Attention LED on the front bezel of the
storage subsystem. (Figure 99 on page 164 shows the location of the Overall
DS4800 Configuration Needs Attention LED on the front bezel.)
