16Power supply installation
Note the following information:
•If a power supply fails when you have a redundant power supply installed, the Ethernet Routing Switch 8300 continues to operate with no interruption of service. The chassis will continue to supply the same module and PoE output power with the remaining power supplies. A trap and syslog message will indicate that the configuration is
•Nortel recommends that you operate the Ethernet Routing Switch 8300 in a redundant configuration at all times to ensure maximum network up time.
•Nortel recommends that you install each power supply on its own dedicated branch circuit. When you plug the power cord for each power supply into a separate AC circuit, the redundant power supply also provides protection against the disconnection or failure of an individual branch circuit or power supply failure.
•If you have installed a redundant power supply, power available for PoE is always determined on an N+1 redundancy. If you have 1 or 2 power supplies in the chassis, you will be allocated PoE power equivalent to one power supply. If you have 3 power supplies in the chassis, you will be allocated PoE power equivalent to 2 power supplies.
