Designating the Shelf Number
The term “shelf” is used in this section in order to retain consistency with
Program Interface terminology. The terms “shelf” and “cage” are identical.
Each peripheral card must be recognized by the main shelf. Therefore, Coral IPx 500
must be able to distinguish between the first and second expansion shelves. The main
shelf is designated 0 by the manufacturer. The first expansion shelf is designated 1.
The second expansion shelf is designated 2. Jumpers are used to configure the shelf
number.
Figure 3-11
displays the jumper configuration for each cage designation.

Designating Synchronization Slots
Two synchronization sources may be defined for the Coral IPx 500 system. One serves
as the primary source, and the other serves as a secondary synchronization signal
source. A total of six slots are factory set to accept digital trunk cards to operate in
slave clock mode. Two slots are located in the Coral IPx 500 main cage and the
additional two slots are pre-wired in each of the IPx 500 expansion cages. Card slot # 4
in all cages is wired to operate as the primary external clock synchronization source
(marked SYNC-PRIME). Card slot # 5 in all cages is wired as the secondary external
clock synchronization source (marked SYNC-SECOND). The cage is shipped from the
manufacturer with the primary and secondary synchronization cards assembled in
slots 4 and 5 of the main cage. The expansion cage can house the primary and/or
Do not connect configuration jumpers of different shelves to identical settings. Doing so
will result in short circuit and system malfunction.
