A-8 System Cabling
RAID Configuration
One of the options available for your system is the NEC SecuRAID 110 or 210 (Mylex AcceleRAID
150 or 250) RAID Controller board, which gives your system the added security of fault tolerance.
If you order a system with the RAID controller, the system is pre-cabled at the factory (see RAID
System Cabling Configuration illustration below).
If you are adding the SecuRAID Controller to an existing system, you must install, cable, and
configure the controller. Refer to
The Installing an Option Board
section in the
Upgrades and
Options
chapter to install the controller. Once you have installed the controller, plug the wide SCSI
interface cable into the connector on the RAID controller (see illustration below).
Note:
Next Boot Status for the first Symbios SYM53C875 controller must be
turned
OFF
if you install the optional Mylex AcceleRAID 150 or 250 Controller
board in your system. Refer to “Symbios Configuration Utility” found in
Chapter 3.
Note:
Ensure JP10 of the Mylex AcceleRAID 150 or 250 Controller board has the
jumper removed. Refer to the Mylex AcceleRAID 250 Installation Guide for the
location of jumper JP10.
