4. Replacing Enclosure Components
This chapter describes how to replace each component in the enclosure in the following
sections:
• “Replacing a Failed Disk Drive” on page 43
• “Replacing a Failed Power/Fan Module” on page 46
• “Replacing a Failed RAID Controller Module” on page 49
• “Replacing a Failed Environmental Status Module” on page 55
• “Upgrading Drives” on page 57
• “Adding Expansion Enclosures” on page 61
Replacing a Failed Disk Drive
When the storage management software (TPSSM) instructs you to replace a failed drive
module, read “The Disk Drives” on page 17, and then follow the steps in this section.
To prevent loss of access to data, remove only a failed drive that has a drive Fault light
on and the drive Service Action Allowed light on, or has a Failed status in the storage
management software.
Warning: Electrostatic discharge can damage sensitive components. Use a grounded
wrist strap or other antistatic precautions before handling enclosure components.
