Redundant Installation
Some Encore systems may be equipped with redundant System Controller
Boards (SCBs). In this case, the recommended arrangement is to install a
redundant CM-4400 and connect the CMs to the SCBs with a BOP 4000
Break Out Panel. See Figure22. Details of the Encore connection are pre-
sented below.

The Double-Y Cable
A Grass Valley Cat5 cable kit is available in two versions:
• If the System Controller Board (SCB) is
the old style (071 0884 xx
series), order kit 174 8216 xx.
• If the SCB is the new style (071 1000 xx series), order kit 174 8217 xx.
The factory cable must be used with a custom
er-supplied adapter, wired as
shown in Figure 20 on page 57. Note that the cables in this kit are eight
inches long. Further instructions ar
e provided with the cable kit.
The rack mount BOP 4000 Break Out Panel / cable kit
is available for
making Y connections to redundant CMs. For more information, see Alarms
