Installing a BIM

Prerequisites

Procedure steps

241-1501-240 5.2S2

Install a breaker interface module (BIM) to control the power supply to the

power interface modules (PIMs) and to the cooling unit or units.

Risk of equipment damage by mixing BIMs

You must never mix a 20-amp BIM (NT6C60PA) and a

25-amp (AP6C67PA) together to power the same shelf.

Mixing BIMs in a pair will damage the equipment.

You must be familiar with "Safety considerations and best practices"

You need a BIM with PEC AP6C67PA for a Passport 20000 or

NT6C60PA for a Passport 15000. The PEC of a replacement BIM must

match the PEC of the previous BIM. When adding a second switch to a

NEBS 2000 frame, you need a pair of BIMs matched with the same PEC

and matched to the switch hardware they will power. Refer to

241-1501-200 Passport 15000, 20000 Hardware Description for the safe

combinations of BIMs within a BIP.

A BIP can contain the BIMs for a second switch before the switch is

installed in the same NEBS 2000 frame. That is, the BIP may have been

shipped with the second pair already installed.

When adding a pair of BIMs to power a second switch, the 2 left-hand BIM

slots are likely to be covered by BIM ﬁller plates (P0887704) at the front

of the BIP. When the ﬁller plates are present, you must:

unfasten the 2 slotted captive screws of the cover of the BIM captive

screws as shown in the ﬁgure "Physical characteristics of a BIM in a

BIP" (page 377) and let the cover swing down

remove each BIM ﬁller plate by unfastening the large slotted captive

screw at the front of the BIP

put the plates aside for re-use on another BIP
