Disk devices mounted within the processor module are wired directly to the rib-
bon cable connectors. This wiring is added during manufacture of the module;
two connection options are available:
•
One disk per processor board — each of the four disks is connected to SCSI
bus 0 on the processor board.
•
A pair of disks connected to processor boards 0 and 1, each using a separate
SCSI bus.
Installing the Disk Devices
The four disk devices within the processor module are each mounted in a remov-
able disk carrier. The disk carrier is connected to the module backplane by a 50-
way connector that carries power, indicator signals, and the SCSI bus.
Warning – You must disconnect the module fr om the power supply befor e
installing a disk device.
Fixing the Disk Device into the Carrier
To install a 3.5” SCSI disk into a disk carrier:
•
Remove the base plate from the carrier by removing the 6 screws.
•
Connect the disk to the power supply and SCSI bus connectors.
•
At the front of the disk connect the LED activity output to the disk carrier.
•
Mount the disk drive into the carrier using four screws that are inserted from
two sides of the carrier. Note that the screw must be long enough to
accommodate the thickness of the carrier wall.
Fixing the Carrier into the Processor Module
Insert the carrier into the processor module so that the indicator lights on the front
of the carrier are at the top. Push into position and secure with the two captive
screws.
