Module Replacement Procedures
The following procedures describe how to replace the storage system modules.
NOTE! The term hot pluggable, refers to modules that can be replaced while the host and
storage system are operating. Not all modules are hot pluggable, and some modules require the
use of command line utilities before removal and after replacement. See Table 1 in Chapter 2 for
HP system support of hot pluggable modules.
Fan Module Replacement Procedure
WARNING! You can only replace one fan module at a time. Do not remove a failed fan
module from the storage system until the replacement fan module is ready to be installed.
Both fan modules must be installed for proper air flow and cooling.
NOTE! You can replace a fan module while the host and the storage system are operating.
To replace a fan module:
1. Remove the fan module from the storage system (see Figure 24).
2. Install a new fan module into the storage system (see Figure 25).
