3300 ICP Technician’s Handbook
Add Controller FRUs
This section contains detailed information on adding the 3300 ICP Field
Replaceable Units (FRUs). See Appendix E FRU Part Numbers beginning
on page 365 for a list of FRU part numbers.
The section is organized as follows:
“MXe RAID Controller” on page 116
“Redundant Hard Drive (MXe)” on page 117
“Application Processor Card (CXi)” on page 118
“APC Hard Drive (CXi)” on page 121
“Redundant Power Supply (MXe)” on page 123
“E2T Processor (MXe)” on page 123.
MXe RAID Controller
The RAID (redundant array of independent disks) controller will mirror all
data on two hard drives. In the event that one drive fails, the system will
continue to operate on the remaining drive. Refer to Knowledge Base
Article 06-2806-00012 “RAID Controller Operations Manual” for RAID
operation details.
Tip: The CX/CXi/MXe controllers are shipped with the Analog Main Board
installed. If you receive a CX/CXi/MXe and the AMB is not installed, refer to
page 136 for installation instructions.
Tip: See also “Add or Replace Controller FRUs” on page 104 and “Replace
Controller FRUs” on page 125.
CAUTION: The RAID controller does not protect against loss
of data as a result of a power outage. You must provide an
Interruptible Power Supply (UPS) to protect your system
data from an electrical disturbance.
Tip: It is very important to maintain current database backups; backups
should be done on a regular basis even when you have disk redundancy.
