Installing the PMC SCSI-2 Adapter

2-11

Make sure the electrical configuration (single-ended or 
differential) of the PMC Adapter matches the common 
termination type of the device(s) that will be connected 
to the SCSI bus. A mixed installation can cause electrical 
damage to both the peripherals and to the PMC 
Adapter.

Your computer operates with voltages that can be lethal. 
Before you remove the computer cover, carefully review 
the steps in this procedure and observe all cautions and 
warnings to protect yourself and to prevent damage to 
the system.

1. With power disconnected and the motherboardÕs faceplate 

screws unfastened, remove the motherboard from the system 
chassis.

2. Remove the spring metal clip covering the mezzanine 

aperture on the face plate of the motherboard.

3. With a grounding strap attached to your wrist or ankle, 

carefully remove the adapter from its antistatic bag.

4. Set the jumpers on the PMC Adapter as described in 

.

The SCSI bus (cable) must be properly 

terminated at each end of the bus. The first and last device on 
the bus should be the only devices that are set to provide this 
function. 

 The SCSI terminators require adequate 

voltage to properly terminate the cable. All SCSI host 
adapters on the bus should be set to supply terminator 
power; and where possible, be located at the end of the bus 
and serve as cable terminators.
