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 non-redundant.
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.
