RAID Storage Components
The RAID Storage chassis contains the components listed below.
• One (PRS250) or two (PRS250M) storage-control processors (SP).
• 10, 15, or 20 disk drive modules.
• One fan module.
• Three voltage semi-regulated converters (VSCs) power supplies
The SPs, disk modules, fan module, and VSCs in the RAID Storage chassis are
customer-replaceable units (CRUs), which you can install or replace yourself.
The following illustration shows the location of the RAID’s CRUs, which also
include the SCSI bus cable, SCSI terminator plug, power cord, and the optional
asynchronous cables. In addition to the CRUs, the RAID Storage chassis contains
field-replaceable units (FRUs). Only qualified service personnel should replace an
FRU.
