4-2 CHP Max™ Headend Optics Platform Chassis, Controllers and Power Supplies Rev D
The CHP Max AC power supply (P/N CHP-PS/AC1-Q-NP) is intended for international
customers who cannot use the US standard power cord. No power cord is included and the
customer must order the appropriate power cord separately (refer to Table 4.1 on page 4-2).
Although each chassis requires only one power supply, the CHP chassis accepts two power
supplies. Isolated outputs allow the primary and redundant supplies to operate in a
power-sharing configuration. Should the primary power source fail, a second power supply
provides all necessary DC power.

AC Power Supply
The module converts the AC input into four DC voltages: +12.0V
DC
, +5.0V
DC
, +3.5V
DC
, and
–5.0V
DC
. These voltages pass through the DC output connector on the rear of the power
supply to the chassis backplane, which routes them to the installed application modules.
Integrated management circuitry provides digital representations of internal temperature,
power supply output voltages, and fan current for status monitoring. Management signals
enter and exit through the multi-pin connector on each power supply’s rear panel.
The CHP-PS/AC1-Q and CHP-PS/AC1-SW AC input power supplies include a power cord for

United States installations. Other available power cords are listed in the following
table for installations in countries that do not use the 115V
