At the purple field, locate the port jack number identified on the Port Assignment
Record and punch-down the other end of the jumper wires onto the connecting
block terminals associated with the port jack.
Route jumper wires around the pegs on the 187B1 backboards to take up slack.
Update the Port Assignment Record.
Repeat the procedure until all jumper wires are installed.
Update system translations.
Removing Jumper Wires
When it is necessary to remove jumper wires due to voice terminal removal, the voice
terminal must be first disconnected at the information outlet. The jumper wires must then
be completely removed from the cross-connect field. This will provide an accurate visual
indication of available connecting block terminals associated with port and station jacks. Do
not leave partially or totally disconnected jumper wires intermingled with other jumper
wires.
When it is necessary to rearrange jumper wires due to voice terminal moves, it is strongly
recommended that the jumper wires be totally removed and reinstalled even if only one end
of the cross-connection is affected. This will reduce entanglement and help to assure a neat
appearance.

On the Port Assignment Record, locate the connecting block terminals associated
with the jack assignments at the purple and white or blue fields.
At the purple field, remove the jumper wires.
Gently lift the jumper wires straight up, taking up slack, until the wires can be
located by their movements.
Remove the jumper wires from the 187B1 backboards.
Trace the other ends to their connection points at the blue or white field and
remove the wires from the connecting block terminals.
Update the Port Assignment Form.
Update system translations.
Installing and Removing Power Adapter Cords
The power adapter cords are installed as described previously under ADJUNCT
POWERING (see Figure 4-48). The power adapter cords can only be used with the 4-pair
stations. The voice terminal and adjunct should be installed prior to installing the power
adapter cord and jumper wires.
To remove a power adapter cord, proceed as follows:

On the Port Assignment Record, locate the connecting block terminals associated
with the station jack number for the voice terminal receiving remote power.
Locate the power adapter cord connections at the 66-type connecting block (blue
field).
Trace the power adapter cord through the 187B1 backboards to the remote power
supply.
Unplug the power adapter cord at the power supply.
