Shelf alarm connectors (upper and lower shelves)
The shelf alarm connectors allow you to configure the BIP to control more than
one 8010co chassis.
Note: The BIP ships from the factory with default alarm configurations
set for a single chassis in the lower shelf of the rack. If you install a
second chassis, you must also configure the jumper on the alarm module
to support that configuration.
See “Accessing the alarm module” on
page 30 for information about jumper settings for your configuration.
