Breaker Interface Panel - Nortel Passport 15000 Hardware Description

Chapter 2

Breaker interface panel

The breaker interface panel (BIP) provides a central location where redundant
input dc power feeds (nominal -48/-60 V) of up to 100 A are connected and
routed to two or four breaker interface modules (BIMs). Power is distributed
from the BIMs to the shelves and cooling units. Passport 15000 or 20000
supports the use of either a two-BIM (single shelf) or a four-BIM (dual shelf)
BIP. The BIP also contains an alarm module which monitors system parts,
generates alarms, and controls LED status indicators.
The following BIP components and connections are described in this section:
• "Front cover of the BIP" (page 53)
• "Breaker interface modules (BIMs)" (page 54)
• "BIM filler plates" (page 62)
• "Alarm module" (page 62)
• "Alarm cable connectors" (page 68)
• "Power connections to and from the BIP backplane" (page 73)
• "Sources of dc input power to the BIP backplane" (page 83)
• "Grounding the Passport and interworking equipment" (page 85)
See the figure "The BIP in a NEBS 2000 frame, front view" (page 52) for the
location of individual parts, and "Rear of the BIP" (page 53) for the location
of input power cables.
