PG-Flex FCS-718

8.9

Fuse.

  Insert a 3 amp fuse in the equipment bay fuse panel for each circuit (two) where the PG-Flex

CO battery wire is terminated.

8.10

Cabling Verification.

  Verify the following:

The following verifications should be done before any cards are inserted in the
COT shelf.

1

Verify a minimum of -42 Vdc and a maximum of -56 Vdc between:

a

TB1 BATT A (–48 Vdc) and TB3 (BATT RTN) screw terminals on the COT shelf.

b

TB2 BATT B (–48 Vdc) and TB3 (BATT RTN) screw terminals on the COT shelf.

2

Verify the following for the HDSL lines:

If the HDSL lines are not connected properly, the COT will not communicate
with the RT.

a

Visually verify the HDSL lines are terminated properly and with the correct polarity.

b

Verify that the HDSL lines are "dry."

c

Verify 0 Vdc between the Tip and Ring, Tip and Ground, and Ring and Ground of each of
the HDSL circuits terminated on the shelf.

d

Verify > 100 kohm resistance between the Tip and Ring, Tip and Ground, and Ring and
Ground of each of the HDSL circuits terminated on the shelf.

3

Replace the clear Plexiglas cover on the rear of the COT shelf.
