The Input/Output (I/O) cables are described in further detail in
Chapter 6 - Cage
Description
. Read the entire chapter before attempting to connect the I/O cables.
Champ Connections
1. Determine the route of I/O cables from the MDF to the I/O Champ connectors of
the card cage and measure the longest distance from an I/O connector on the card
cage to the corresponding cable punch block on the MDF.
2. Prepare cables that are the length determined above, with a male 25 pair connector
on one end, for each I/O connector on the card cage. Eight 25 pair cables are
required for main cages and twelve cables are required for expansion cages.
3. Carefully route the connector end of the first cable to the left I/O connector. Insert
the cable connector firmly into the Coral I/O connector.
4. Route the other end of the cable to the appropriate cable punch block on the MDF.
5. Repeat this procedure for each I/O cable, moving from left to right across the
upper I/O connectors, and then from left to right across the lower I/O connectors,
until all cables are in place.
6. Mark each I/O cable near the connector on the card cage rear panel with the
corresponding peripheral shelf and I/O connector number on the Coral system.
7. Terminate each of the cables in their respective cable punch blocks on the MDF.
8. Mark each cable punch block with the corresponding I/O connector number on
the Coral system. Optionally mark every eighth pair on the block, starting with
the first pair, with the number of the two card slots associated with the I/O cable,
according to
Table 2-7
and
Figure 2-16
.
Ensure that each I/O cable is secured with its own hook-and-loop fastener
strap on the Coral cabinet rear, so that the cables do not accidentally pop out
of place.
