Procedure steps
241-1501-240 5.2S2
Install the shelf-based breaker interface panel (BIP) into a mounting
apparatus other than a NEBS 2000 frame to distribute power to the Passport
switch hardware.
• You must be familiar with "Safety considerations and best practices"
(page 53).
• You need a BIP with one of the following PECs:
— NT6C62 for a Passport 15000
— AP6C68 for a Passport 20000
• When installing the BIP in a rack other than a NEBS 2000 frame, a
secondary grounding point is provided in the BIP chassis. There are two
studs at the rear lower right of the chassis. Use two straight 2-hole lugs,
one to the chassis and the other to the rack ground bonding point. Ground
the BIP chassis to the rack by firmly attaching a ground of minimum size
6 AWG cable E/W (13.3 mm
grounding point. The stud nuts on the chassis are number 10-32 unc and
are included with washers on the studs. Use star washers between the lug
and the rack. Do not overtighten the nuts.
1 Hold the BIP so that the side with the openings faces you.
2 While facing the front of the rack, insert the BIP between the adapter
brackets and above the shelf.
3 Gently lower the BIP until the bottom edge of its mounting ears touch the
top edge of the shelf mounting ears. Prevent the weight of the BIP from
resting on the shelf.
4 Align the screw holes on the 2 mounting ears with the nearest holes on
the outside face of the adapter brackets. Loosely fasten a thread-forming
10-mm (3/8-in.) head-hex screw from pack P0601478 through the upper
left mounting-ear hole.
5 Loosely fasten another screw through the lower right mounting-ear hole,
then the remaining 2.
6 Center the unit, then tighten all 4 screws to snug plus a 1/4 turn.
