XII.1.C.1. CONNECTIONS IN THE MAIN RACK:
XII.1.C.1.1. INTEGRATION OF THE CLOCK MASTER CARD TO THE
MAIN RACK:
The critical thing at this point, which must be done in the first stage, is to install the CC-EXT
chip, which comes in its special box with the 4
th
rack parts, in the vacant socket that is on the
CPU200 card. For that purpose, first, CPU200 is detached from the smaller module card
connector which is on the base card. The chip, which comes together with the 4
th
rack parts,
is installed in the vacant socket that is located in the section underneath that card. A similar
operation has to be carried out for the redundant CPU200 card as well, if there is one. If
there is no redundant CPU200 card in the system whose installation is to be performed, then
the redundant chip that has come should be kept in an appropriate place for later use.

PRIOR TO INSTALLATION OF SYSTEMS WITH 4 OR MORE RACKS, THE
CC_EXT CHIP, WHICH COMES TOGETHER WITH THE 4
TH
RACK PARTS, MUST
BE PLUGGED IN THE VACANT SOCKET ON THE CPU200 CARD.
The Clock Master card must be installed in the main rack on which CPU200 is present.
Structure of this card allows it to be attached to the plastic card slots of DS200 and its
dimensions are the same as those of the CPU200 card. However, since it has no connection
to the backplane, there is no 64-pin male connector on the back of the card. Instead, it is
connected through a BPL200-FC to the inter-rack connector that is at the lower section on
the BPL200 backplane of the main rack, at the same level with the CPU200 card.
The Clock Master card is plugged in the slot that is situated to the left of the CPUKON card.
Cable connections have to be made before the card is completely placed into the slot.
The procedure for that:
1) One end of the BPL200-FC is attached to the inter-rack connector that is at the lower
edge of the BPL200-MAIN backplane of the main rack.
2) The other end of the BPL200-FC is attached to the similar connector that is on the Clock
Master card.
3) The PCM carrier cables are connected to the five RJ45 connectors that are on the Clock
Master card. Paying attention to the order of those cables while connecting is very
important, because those cables will be connected to the second rack in the same order.
