Removing the Resistor Packs
Grasp the resistor pack near one end and
gently lift until the pins are
exposed. Do not remove all
the way. Repeat for the
other end. Grasp the
resistor pack from the
center and remove.
Repeat for the remain-
ing two resistor packs.
Storing the Resistor
Packs
Place the resistor packs in a safe place. When
connecting only internal or external SCSI devices, the resistor
packs will need to be reinstalled.
Installing the Resistor Packs
To reinstall a resistor pack,
PIN
1 of the resistor pack
MUST
be
aligned with
PIN
1 of the socket. The resistor packs are marked
on a side with either an arrow or a dot which indicates the
PIN
1
location.
• Align the dot (or arrow) of the
resistor pack with the marking on
the board as shown. Be sure all pins
of the resistor pack are aligned with
a hole of the socket.
• Press down evenly until the resistor
pack pins are no longer visible; the
resistor pack is seated in the socket.
• Repeat for the remaining resistor
modules.

Termination
Resistors
If the resistor packs are being removed for the first time,
they will be tightly seated in the sockets. Tweezers (i.e. needle-nose)
can be used to remove the resistor packs more easily.

OTE
If you are installing both internal and external peripherals
remove the three termination resistor packs on the SCSI Card
1505. See the SCSI Card 1505 User’s Reference (page 3,
Terminating the SCSI Bus) for additional information on
termination.
