ACX6160 Component Redundancy

The following hardware components provide redundancy on an ACX6160:
• Power supplies—The ACX6160 has two power supplies. Each power supply provides power to all
components in the device. The two power supplies provide full power redundancy to the device. If
one power supply fails or is removed, the second power supply balances the electrical load without
interruption. To provide power redundancy to the system, you must install both power supplies.
Connect power source feed A to one power supply and power source feed B to the second power
supply.
CAUTION: Do not connect feed A and feed B to the same power supply input
terminal.
• Cooling system—The ACX6160 has five fan modules. If a fan module fails and the remaining fan
modules are unable to keep the ACX6160 within the acceptable temperature thresholds, chassis
alarms occur and the ACX6160 can shut down.
CAUTION: Replace a failed fan module with a new fan module within 4 minutes of
removal to prevent chassis overheating.
