Central office alarms
The central office alarm connectors allow you to aggregate alarms from multiple
BIPs and route them to an aisle alarm and to the central office.
Figure 7 shows
three BIPs configured to aggregate alarms from three racks. You can configure up
to ten BIPs in a series configuration to aggregate alarms.
Central office alarm cables are not provided as part of your BIP shipment. To
build your own central office alarm cables, see
Appendix B, “BIP external cable
pin assignments,” on page 75 .

You can also configure one or more standalone BIPs to individually report alarm
status to the central office (
Figure 8 on page 27 ).
