6. Removing and Replacing Customer-Replaceable Units
This chapter describes the installation and removal procedures for customer-replaceable
units (CRUs) in the SGI 2400 and 2800 rackmount systems. The CRUs are hardware
components that can be safely removed by an end user without undue exposure to high
electrical power potentials. CRUs are limited to the following major components (see
Figure 6-1):
• drive modules
• module System Controller (MSC)
Warning: Do not attempt to remove or replace hardware components (such as
boards) that are not listed above. This system uses internal electrical power that is
hazardous if the equipment is improperly disassembled. Failure to heed this warning
may not only void the system warranty but could cause personal injury.
