Installing a BIM
Install a breaker interface module (BIM) to control the power supply to the
power interface modules (PIMs) and to the cooling unit or units.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• 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.
Procedure steps
1 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
CAUTION
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.
