Reinstall the Battery Enclosure
If you removed the battery enclosure to provide additional space in the cabinet or EXM when installing or splicing outside
plant metallic cables, reinstall the battery enclosure as described below.
To reinstall the battery enclosure
Place the battery enclosure in base of the FAC 900 or EXM, aligning the mounting bracket holes against the
counterpart holes on the equipment rack.
Install the eight mounting screws (4 per side) to secure the enclosure to the rack. Tighten the screws to 45 in.
lbs. of torque.
Ensure that the front bottom edge of the enclosure is up against the inside lip of the door jam. If not, loosen the
screws that mount the rails to the top and bottom of the FAC 900 or EXM, pull the battery enclosure forward,
and then re-tighten the screws.
Replace the retaining bracket and terminal cover.
Close the door and check to be sure that the battery housing properly seals against the door gasket. For
the FAC 900, this can be viewed through the front equipment compartment; for the EXM, this can be viewed
through the rear access panel using a flashlight.
Installing 5-Pin Protection Modules
To complete the circuit connections between the metallic outside plant cables and equipment, you must install 5-pin protec-
tion modules into the 50-pair protection blocks. The 5-pin protection modules serve as fuses to protect the equipment from
electrical surges on the lines.
Each 5-pin position on the block protects one wire pair (one 2-wire circuit). Install a 5-pin protection module into each block
position (circuit) that will be equipped for service. Refer to the cabinet pair assignment list for more information.
Note:
Clearfield equipment uses a 'dead pair' scheme, where the 25th pair in each 25-pair cable group is unterminated
(dead). Therefore, on each protection block, positions 25 and 50 are not wired. Line identification labels cover the dead pair
positions.
