pushed in so as to fit tightly into its corresponding connector on the BPL200-Backplane.
When the module has been completely fitted, it is fixed by using the fixing latches on the
front cover of the card.
In case it is necessary to take CPU200 out of the rack, the card fixing latches on the front
card cover of CPU200 should be pressed toward the sticker that is on the holder and then
the module should be pulled out cautiously until DS200 CPU-FC appears. As the final step,
DS200 CPU-FC is detached from CPU200 and then the module is taken out of the rack.
In case it is necessary to take DS200 CPUKON out of the rack, the card fixing latches on the
front card cover should be pressed toward the sticker that is on the holder and then the
module should be pulled out cautiously until DS200 CPU-FC appears. After that, DS200
CPU-FC is detached from DS200 CPUKON and then the card is taken out of the rack.
If using a redundant CPU200 card is needed in the system, then that card is installed in the
special slot which is reserved for it, and which is just to the right of the CPU200 card by
following the same installation steps as that for the CPU200 card. Its connection with the
DS200 CPUKON card is provided by DS200 CPU-FC.

THE CPU200 CARD MUST NOT BE REMOVED WHILE THE EXCHANGE IS
OPERATING.
XIV.1.B. THE UTIL200 UTILITY MODULE
The UTIL200 Utility Module has been placed on the related plastic card slot in the rack. The
UTIL200 module is situated between the CPU200 and DS200 CPUKON cards in the main
rack. The DS200 CPU-FC cable extends behind the UTIL200 module. On the other hand, the
UTIL200 card is attached to the leftmost slot in the auxiliary racks.
In order to place UTIL200 into the rack, back corners of the module is fitted into the plastic
card slot channel. At this point, the module is supposed to be pushed into the rack so that
the connector behind it fits tightly into its corresponding connector on BPL200-MAIN or
BPL200-AUX. (While the UTIL200 that is in the main rack is being installed, one should
make sure that the DS200 CPU FC cable remains behind the card.) When the module has
been completely fitted, it is fixed by using the fixing latches on the plastic card holder.
In case it is necessary to take UTIL200 out of the rack, the card fixing latches on the front
cover of the card is pressed toward the sticker on the holder and then the module should be
taken out of the rack.
