Understanding Hardware Redundancy of an ACX5000 Router Components
and Functionality
The following hardware components provide redundancy on an ACX5000 router:
Power supplies—The ACX5000 router has one or two power supplies. Each power supply provides
power to all components in the router. If two power supplies are installed, 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 both power supplies must be installed. Connect power
source feed A to one power supply and power source feed B to the second power supply.
CAUTION:
terminal.
Cooling system—The 1 U ACX5048 router has five fan modules; the 2 U ACX5096 router has three fan
modules. If a fan module fails and is unable to keep the ACX5000 router within the desired temperature
thresholds, chassis alarms occur and the ACX5000 router can shut down.
