out MS128 CPUKON from the cabinet, the top cover of CBN128 cabinet must be
opened, MS128 CPU-FC must be disconnected and then, the screw fixing the card
to the brass card holder on rack top plate must be loosened and the card must be
removed from the brass and plastic card holders. Later on, the card can be installed

EXPANSION MODULES
MS128 EX1 consists of MS128 EX1B and KN1 cards together with EX-FC flat
cable. Similarly, MS128 EX2 includes MS128 EX2B and KN2 cards together with
EX-FC flat cable. The parts of each module are packed in the same cardboard box,
although they are not connected to each other.
The first step of installation is, to locate the KN1 or KN2 card in the cabinet. For
each KN1 or KN2 card, there are one brass and two plastic card holders on the rack
top plate. To locate the card, the top cover of CBN128 cabinet must be opened and
then, the card must be placed on the corresponding card holders on the rack top
plate. The KN1 or KN2 card must be then fastened to the brass card holder with its
screw.
The second step is, to attach the EX-FC cable to KN1 or KN2 card. For this, one of
the free ends of the cable must be attached to KN1 or KN2 card and then, the other
free end must be passed through the corresponding cable hole on the rack top plate
(see Figure B-5).
The third step is, to locate the MS128 EX1B or MS128 EX2B card in the cabinet.
For this, the back corners of the card must be placed in between the top and bottom
metal card slots and then, the card must be pushed inside the cabinet (see Figure
B-6). When the card is inserted completely, the card must be fastened by the latch
at the top of the plastic card cover and then, EX-FC coming from the corresponding
KN1 or KN2 card must be plugged to MS128 EX1B or MS128 EX2B card (see
Figure B-5).
