Accessing the alarm module

Danger: Ensure that the DC power source is off or disconnected at the remote end before you perform any of the steps in this section. Be sure that the DC input source power is locked out and tagged.

The alarm module contains jumpers that you can configure to allow the BIP to monitor the shelf alarm cables for a single or dual chassis installation. The BIP ships from the factory with default jumper configurations set for a single chassis in the lower shelf of the rack. If you install a second chassis in the upper shelf, you must configure the jumpers on the alarm module to support that configuration.

Note: The jumper configuration has no affect on the chassis status alarms.

The BIP front panel opens to provide access to the jumpers on the alarm module.

To open the front panel:

1Using a Phillips screwdriver, loosen the two front panel locking screws (Figure 11).
