PC Card Installation
St ep 1
Turn off the power to the computer.
St ep 2
Remove the computer's cover to access the internal slots where peripheral cards are added.
St ep 3
Remove the sheet metal bracket that covers the external access slot. Save the screw. On IBM
AT and IBM AT-compatible computers, this is at the rear access panel where all external
connections are made. This bracket is replaced by the bracket on the end of the OEM-AT6400
card.
St ep 4
Select a 16-bit slot to install the OEM-AT6400 card.
CAUTION
While handling the OEM-AT6400 card, be sure to observe proper grounding techniques to
prevent electro-static discharge (ESD).
St ep 5
Make sure that there are two empty slots immediately next to the right side (when you are
facing the front of the computer) of this slot. (This is to allow enough room to maneuver
when attaching the 60-pin ribbon cable.) Temporarily remove cards from adjacent slots, if
necessary.

Orienting the 60-pin ribbon connector with the stripe on top and the holes of the connector
facing to the left (when you are facing the front of the computer), insert the connector into the
computer chassis through the access slot for the designated card slot. Pull several inches of
the cable through the slot, folding it to the right (when you are facing the front of the
computer) and flat against the back of the chassis to get it out of the way. Secure the cable
and connector temporarily to leave both hands free for installation of the OEM-AT6400 card.
(The connector can be temporarily pushed back through one of the empty adjacent access slots
to secure it.) See the drawing on the next page.
St ep 7
Insert the bottom corner of the OEM-AT6400 PC card into the card guide slot near the front of
the computer. Ease both ends of the card simultaneously down into the computer until the
card's edge connector reaches the computer's mating connector (see drawing below). (If using
the VM60, make sure that the ribbon cable is properly seated with the bracket on the OEM-
AT6400 card.) Adjust the card until the edge connectors align and press it down into the
mating connector.
St ep 8
- F O R V M 6 0 O P T I O N O N L Y -
Adjust the 60-pin ribbon cable to align the mating connector with the 60-pin connector on the
OEM-AT6400. (The 60-pin ribbon cable can be somewhat stiff. Bend it gently when
aligning the connectors.) When properly aligned, gently press the connector until it seats with
the mating connector. If the connectors need to be separated for troubleshooting or repair
purposes, insert a small slot-head screw driver into the slot on the top of the mating connector
(looking down into the chassis), between the connector body and the metal tab, and twist.
NOTE: Make sure that the 60-pin ribbon cable is installed with the stripe on top before
attempting to use the OEM-AT6400. Also, make sure the cable end installed on the VM60
has the stripe oriented towards the pin-1 side of the VM60. Improper installation of this cable
can severely damage the OEM-AT6400.
St ep 9
Using the screw that secured the original access slot cover bracket, fasten the OEM-AT6400
mounting bracket to the computer chassis (see drawing above).
