Hardware Preparation and Installation
After you have completed the rack or pedestal installation of the
XR900 chassis and associated equipment, proceed as follows to
cable the hardware together.
All rack cabling should be contained within the rack
bay. Cabling to external peripheral equipment should
be routed through the rear panel of the rack.
1. Attach one end of an SCSI cable to the lower of the two 68-pin
For the differential enclosure, make sure the cabling is
connected to a differential controller.
2. Locate the upper SCSI connector on the back of the existing
integral SCSI peripheral expansion chassis (if one is present)
or the appropriate SCSI connector on the back of the Modular
Chassis. Remove the terminator block and plug the other end
of the SCSI cable into that connector.
3. Move the terminator block to the unused upper SCSI
connector on the XR900 chassis.
On the differential enclosure, you must use a
4. To connect the environmental monitor circuitry, attach an
RJ45 cable to the lower of the two RJ45 connectors (identified
on the back of the XR900 chassis
