Install the New A and B Position Carriers
1. Install the J58890AF Expansion Control Carrier in position “A” by lining up
the plastic alignment tips on the top rear of the carrier with the screw holes
in the cabinet. These alignment tips will support the carrier while the
screws are being replaced. Ensure that the power cords are properly
placed in the slots at the sides of the carrier.
2. Fasten the carrier into position with 4 self-tapping screws saved from the
removal of the old carrier.
!
CAUTION:
Carefully realign the threads on the self-tapping screws by turning
them counterclockwise 1 turn before tightening them to avoid
stripping the threads out of the framework.
3. Behind the carrier in a “DEFINITY style” cabinet, replace the 2 screws
saved from the removal of the old carrier.
4. Install the J58890BB-3 port carrier in position “B” by lining up the plastic
alignment tips on the top rear of the carrier with the screw holes in the
cabinet. These alignment tips support the carrier while the screws are
being replaced. Ensure the power cords are properly placed in the slots at
the sides of the carrier.
5. Fasten the carrier into position with 4 self-tapping screws saved from the
removal of the old carrier.
6. Connect the “P2” and “P1” (large and small) connectors to the “A” carrier.
Snap the connector lock into place to ensure the connection is properly
made. See
Figure 5-25
.
7. Connect the “P1” (small) connector to the “B” carrier. To get enough slack
in the cables, cut the tie wrap holding the intercabinet cables from the
upright in the area of the carrier being installed. Snap the connector lock
into place to ensure the connection is properly made.
8. Connect the 8 ground straps from the “D” carrier to the new “A” carrier.
See
Figure 5-24

9. Connect the 8 ground straps from the “C” carrier to the new “B” carrier.
These straps were left connected to the “C” carrier.
10. Install the 8 ground straps between the new “A” and “B” carriers. These
straps were removed from the old carriers.
11. For an AC-powered expansion control carrier, install the 2 new carrier
ground straps. One strap connects ground point “1” to the A-carrier frame
(on the right side), and the other connects ground point “8” to the A-carrier
frame (on the left side).
NOTE:
DC-powered carriers do not use these carrier ground straps.
