Overview
This chapter describes removal and replacement procedures for the disk array hot-
swappable modules that are customer replaceable. Hot-swappable modules can be
replaced without impacting host interaction with the disk array.
Procedures for replacing the following modules are included in this chapter:
• Disk Enclosure
– Disk Modules
– Power Supply Modules
– Fan Modules
• Disk Array Controller Enclosure
– Battery Backup Module
– Controller Fan Module
– Power Supply Modules

All modules other than those listed above must be replaced by a trained service

Note What is a “hot-swappable” component?
The term hot-swappable identifies a component that can be removed and
replaced without disrupting host access to the disk array. Host I/Os continue
without interruption when replacing a hot-swappable component. Disk array
controller modules, disk modules, power supply modules, and fan modules are
all hot swappable components.
