416 Hardware Description and Reference for Avaya Communication Manager
DC power-distribution unit (J58890CG)
The J58890CG is used with SCC1s. Individual DC output connectors can provide power for up
to four SCC1s. Each output connector is separately fused at 25 A. The fuses are inside the DC
power-distribution unit. The input for the DC distribution unit is from the DC power cabinet.
Use the J58890CG DC power-distribution unit when the distance between the DC power
cabinet and the cabinet stack is greater than 30 feet (9 meters).
Enhanced DC rectifier cabinet (J58890R)
The J58890R enhanced DC rectifier cabinet is used with SCC1s. Each rectifier assembly in the
DC rectifier cabinet can supply up to 50 A of DC current. You can install a minimum of two
rectifiers in each DC cabinet to supply a total of 100 A. A third rectifier assembly is used as a
backup only.
Each SCC1 can draw up to 15 A. Up to three DC cabinets can be stacked to supply power to
single-carrier cabinets stacks.
Each output connector is separately fused at 25 A. The fuses are inside each DC rectifier
assembly.
Note:
Note: A J58890CG DC power-distribution unit is required if the distance between the
DC cabinet and the cabinet stack is greater than 30 feet (9 meters).
CMC1 AC power supply (650A)
In the CMC1, a power cord with a three-prong plug on one end and an appliance connector on
the other end connects the supply to a dedicated AC power source. The power supply is an AC/
DC converter that is corrected for global power factors. The converter provides multiple DC
outputs and AC ring outputs. The converter is autoranging
● 85 to 264 VAC, 47 to 63 Hz, at 330 Watts,
● 4.5 A (100 VAC to 120 VAC) at 500 VA,
● or 2.3 A (200 VAC to 240 VAC) at 500 VA.
The inputs to the power supply can be:
● 120 VAC, 50 Hz to 60 Hz, 6 A, with 3 wires in the power cord: 1 hot wire, 1 neutral wire,
and 1 ground wire
● 220 VAC or 240 VAC, 50 Hz to 60 Hz, 3 A, with 3 wires in the power cord: 1 hot wire, 1
neutral wire, and 1 ground wire
The AC power supply produces the following outputs: +5 VDC, –5 VDC, and –48 VDC. The
outputs distribute power on the cabinet backplane to the circuit pack slots. The AC ringing
voltage output value and frequency depend on the country of use. The 650A also supplies
power at 150 VDC for neon message waiting lamps. The power supply has EMI filtering.
