Preparing the Command Module

This procedure explains how to reduce the overall weight of the 
command module (for lifting purposes) and how to select its host 
SCSI ID settings.

Command Module 
Preparation Notes

It is easier to lift a rackmount command module and set it onto the 
support rails in the cabinet if you remove all the customer replaceable 
units (CRUs) first. CRUs are portable, removable units that house 
the controllers, fans, power supplies, and batteries. A fully loaded 
command module weighs approximately 34.5 kg (76 lb). You can 
reduce the overall weight approximately 18.1 kg (40 lb) by removing 
the controllers, battery, power supplies, and fans.
