How to Install the ASIB1
(SCSI Interface Board) in the
EX5R
Necessary Items
• ASIB1 (SCSI Interface Board) x 1
• SCSI cable (Flat cable 50P; length: 280mm) x 1
(included in the ASIB1 package)
• Cutting pliers or scissors (to cut a cable)
When you open the package of the ASIB1 board, you
will find two SCSI cables connected to the ASIB1,
and two (2-pin) power cables, one is plugged to the
ASIB1 and the other is left unplugged. To install the
ASIB1 into the EX, only the short (280mm long)
SCSI cable is used. First, it is necessary to remove
the long (480mm long) SCSI cable and 2-pin power
cable from the ASIB1 board.
Installation
You can install the ASIB1 after removing the EX5R top
cover. For more information on removing the EX5R top
cover, see How to Remove the EX5R Top Cover.
When installing the optional board (from when you
remove the top cover to when the top cover is replaced
securely) all operations must be done with the power
cord disconnected.
1Remove the two screws from the ASIB1 opening
cover (hold the cover from inside the EX5R as you
remove the cover). The two screws will be used
again when securing the ASIB1. Be careful not to
lose them.
After you take off the cover, do not leave it inside the
EX5R and put it in a safe place.
2Disconnect the long (480mm long) SCSI cable from
the connector (CN1) on the ASIB1 board.

3Unplug the 2-pin power cable from the ASIB1 and
remove it from the ASIB1. To remove the 2-pin
power cable, cut the cable and then pull it out from
the hoop as shown in the illustration.
4Remove the ASIB1 power cable (1 red and 1 white, 2
pin cable) from the hook-shaped bundle tie in the
EX5R. Make sure not to catch the cable on any other
cables or the circuit board while removing it from
the hook-shaped bundle tie and set it aside. Place the
remaining cable back into the bundle tie.
