Figure 12 Accessing the alarm module
Figure 13 shows a close-up view of the alarm module with jumpers J8 and J9
configured to monitor the shelf alarm cable for a single chassis in the lower shelf
only (default setting). Monitoring of the upper shelf alarm cable is disabled with
jumper J8, by default.
To enable the BIP to monitor the shelf alarm cable for a second chassis in the
upper shelf, you must place the upper shelf alarm jumper (J8) over pins 2 and 3.
