AC Power for AC-Powered Systems
AC-POWER
Three different cabinet types are supported as PNs: multicarrier cabinets, single-carrier
cabinets, and the G650 rack mounted cabinets. All types may be powered by either an AC or
DC power source. Environmental maintenance differs according to a cabinet’s type and its
power supply.

! CAUTION:
powering down a cabinet or carrier that contains an EMBEDDED AUDIX
circuit pack (TN566), first power down the AUDIX unit to avoid damaging its
software. Instructions for powering down this unit are in Maintenance Procedures
(03-300432).
Power System for Single-Carrier Cabinet
AC Power
Each single-carrier cabinet has one power supply that distributes DC power and AC ringing
voltage to the circuit pack slots in the cabinet.
AC Power Supply (WP-91153)
In an AC-powered cabinet, a single, plug-in, multi-output AC power supply is in the power
supply slot. A power cord, with a 3-prong plug on one end and an appliance connector on the
other end, connects the supply to a dedicated AC power source. The inputs to the power supply
can be (depending on list version):
● 120 VAC, 60 Hz, 15 to 20 Amp; three wires in the power cord (one hot, one neutral, and
one ground wire)
● 220 VAC or 240 VAC, 50 Hz, 10 Amp; three wires in the power cord (one hot, one neutral,
and one ground wire)
The AC power supply produces the following DC outputs: +5 VDC, -5 VDC, -48 VDC, +12 VDC,
and a battery-charging voltage. The DC outputs distribute power on the cabinet backplane to
the circuit pack slots.
The AC power supply also produces AC ringing voltage. The AC ringing voltage output value
and frequency depend on the country of use. The power supply has a circuit breaker and EMI
filtering.
