To install replacement components, proceed as follows:
1. Identify the proper socket location for the replacement component.
2. Note the half-circle notch or identification mark located on one end of the
component. When installed, the component must be oriented so that its notch or
mark is in the same direction as a similar notch or mark on the socket.
3. Ensure that the component’s contact pins are aligned with the socket’s
receptacles. You may need to adjust the pins (bow them inward or outward) for
proper alignment.
4. Gently press the component into place to properly seat the pins.
CAUTION
If pressure is not uniformly applied, the pins on one side or the other may
buckle and collapse without making proper electrical contact. If this
happens, remove the component, straighten the pins, and try again. If
damage was extensive, you may need a new component.
Termination Power Fuse
-
WARNING
For continued protection, replace only with a fuse of the same
type and rating.
If the termination power (TERMPWR) fuse blows, the SCSI port will no longer supply
termination power to the SCSI bus, and the green TERMPWR LED will turn off.
