Alcatel-Lucent 6600 manual Redundant AC Circuit Recommendation

OmniSwitch 6600 Family Chassis and Hardware Components Backup Power Supply

Redundant AC Circuit Recommendation

When a backup power supply is installed, it is recommended that the AC source connected to the backup power supply resides on a separate circuit from the primary power supply. With redundant AC, if a single circuit fails, the switch’s backup power supply (on a separate circuit) will likely be unaffected and the switch can continue operating.

Note. The switch must have a backup power supply installed for the redundant AC circuit recommenda- tion to be applicable.

The diagram below shows a simple redundant AC circuit scenario for OS6600 Family switches.

AC Circuit 1

Both the primary and redundant power supplies are installed in the chassis, providing power supply redundancy.

Each power supply is connected to an AC source on a separate circuit.

AC 1

In the event of a failure at circuit 1 (for example, a tripped circuit breaker), the redundant power supply plugged into the grounded AC outlet on circuit 2 allows switch operations to continue.
