Passport 15000, 20000 Hardware Installation, Maintenance, and Upgrade
Remove a BIP to replace it for a failure or to upgrade a NEBS 2000 frame
with a Passport 15000 to accommodate a Passport 20000.
CAUTION
Risk of equipment damage from dropping
The various BIPs weigh up to about 16 kg (36 lbs). The
weight of a free-falling BIP can damage it. As the
mounting screws of the BIP are being unfastened, do not
allow the BIP to drop onto the shelf assembly.
• You must be familiar with "Safety considerations and best practices"
(page 53).
• You need a helper to support the BIP while it is unfastened.
1 At the front of the BIP, close the cover of the BIM captive screws by
engaging the 2 slotted captive screws.
2 If the two studs at the rear lower right of the BIP chassis have a cable
fastened to them, unfasten the number 10-32 unc nuts. (It is a secondary
ground bonding point.) Disconnect the cable and put the nuts back on the
studs.
3 Unfasten the 4 thread-forming 10-mm (3/8-in.) hex-head screws that hold
the mounting ears against the frame uprights or adapter brackets. Put the
screws aside for re-use.
While the mounting screws are being unfastened, have a helper be ready
to hold the BIP. Once you begin to loosen the top screws, the rear of the
BIP starts to sag downwards onto the top of the shelf assembly.
4 Remove the BIP by sliding it out the front of the frame or rack.
For the location of the mounting screws, refer to the figure "Locations of
modules in a BIP" (page 654).
