SCSI logic requires that the two devices at opposite ends of the SCSI chain be termi-
nated and that all devices in between be unterminated. The SCSI cable included in the
upgrade kit has an active terminator installed at the end of the cable. Therefore, you
should disable the termination on all SCSI devices you attach to this cable.






 
 
  

To install a peripheral device that uses the system’s integrated SCSI controller, per-
form the following steps.

Ground yourself by touching an unpainted metal surface on the back of the com-
puter, unpack the drive, and compare the jumper and switch settings with those
in the drive documentation. (See “SCSI Configuration Information” found earlier
in this chapter for information on setting the drive's SCSI ID number and enabling
termination [if required].) Change any settings necessary for this system's
configuration.
If the drive does not already have drive rails attached, attach a drive rail to each
side of the drive and secure each drive rail to the drive with a screw in each of the
lower slotted screw holes on the drive rail.
3. Open the computer covers.
4. Disconnect all cables connected to the interposer board on top of the peripherals
bay (see Figure 9-2 and Figure 9-3).
These cables include the system board interface cable, cooling fans wiring har-
ness, interposer board power cable, and control panel cable.
