General Information
Each power supply has a separate backplane connection to allow for
different AC power sources. The power supplies are input rated at 85
to 264 volts alternating current (VAC). The faceplate of each power
supply provides the following status LEDs:
• A green PWR OK LED illuminates if the power supply is
operational and receiving AC power.
•An amber FAULT LED illuminates if the power supply fails.
•An amber TEMP LED illuminates if the power supply shuts
down due to an over temperature condition.
•An amber I LIM LED illuminates if the power supply is
overloaded and operating at the current limit (15.6 amperes).
RFI Shield
The RFI shield covers and provides RFI protection for all rear- access
FRUs except the power module assembly. The RFI shield is
concurrent and can be removed or replaced while the director is
powered on and operating.
Power Module
Assembly
The power module assembly is located at the bottom rear of the
director. The module is a nonconcurrent FRU, and the director must
be powered off prior to scheduled removal and replacement. The
module provides:
• Two single-phase AC power connectors. Each connector is input
rated at 85 to 264 VAC.
• A power switch (circuit breaker) that controls AC power
distribution to both power supplies. The breaker is set manually,
or is automatically tripped by internal software if thermal sensors
indicate the director is overheated.
• A 9-pin maintenance port that provides a connection for a local
terminal or dial-in connection for a remote terminal. Although the
port is typically used by maintenance personnel, operations
personnel use the port to configure network addresses.
• An input filter and AC system harness (internal to the FRU) that
provides the wiring to connect the AC power connectors to the
power switch and power supplies (through the backplane).
