16. Install the front trim plates; first on the “A” carrier, and then on the “B”
carrier.
17. Install the ICC cables (H600-204 G1) between carriers “A” and “B.”
Connect the cables to the “ICC” pin-field block on both carriers (see
Figure 5-27
and
Figure 5-28
and
Table 5-16
). Install the cable so that the
dark stripe is on the bottom at both ends.
!
CAUTION:
While installing the ICC cable connectors, be careful not to bend any
backplane pins. Double check each connection to verify that the
pins are straight.
18. Install the power units (removed from G2 universal module) into the “A”
carrier. There are 4 different pairs of power units available. They are the
631AR1 and 631BR1, the 631WA1 and 631WB1, the 631DA1 and
631DB1, and the 644A and 645B.
Do not interchange the physical locations of the units. Install the 631AR1,
631WA1, 631DA1 or 644A in the left side. Install the 631BR1, 631WB1,
631DB1 or 645B in the right side.
19. If the expansion control carrier contains a 631BR1, 631WB1, or 645B
power unit, install the previously removed TN736 power unit in port slots
“18” and “19” of the carrier (adjacent to the 631BR1, 631WB1, or 645B). If
the system contains neon message waiting, a TN752 or TN755 power unit
must be used.
NOTE:
The TN736 is not required when the 631DB1 or 645B power unit is
used in the J58890AH control carrier or the J58890BB-2 or
J58890BB-3 port carriers. It is required in the J58890BB-1 port
carrier regardless of which 631 power unit is provided. Use the
TN752 or TN755 if the system is equipped with neon message
waiting.
20. Connect the power cords to the power units. The power cords are the
white cables equipped with plugs that are run through the slots in the front
of each carrier.
