How to Install the
EXIDO1 in the EX5/7
Necessary Items
• EXIDO1 (Individual Output Board) x 1
• Flat cable x 1 (included in the EXIDO1 package)
Installation
You can install the EXIDO1 after removing the
optional board cover. For more information on
removing the optional board cover, see How to Remove
the Optional Board Cover.
If the ASIB1 (SCSI Interface Board) is already
installed, it must first be removed before proceeding.
If you want to install the two boards simultaneously,
first install the EXIDO1.
When installing the optional board (from when you
remove the cover to when the cover is replaced
securely) all operations must be done with the power
cord disconnected.
1Remove the two screws from the EXIDO1/EXDGO1
opening cover (hold the cover from inside the EX5/7
as you remove the cover). The two screws will be
used again when securing the EXIDO1. Be careful
not to lose them.
Opening cover
After you take off the cover, do not leave it inside the
EX5/7 and put it in a safe place.
2Remove the EXIDO1/EXDGO1 power cable (1 red
and 4 white, 5 pin cable) from the hook-shaped
bundle tie in the EX5/7. 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.
