Redundant Power Configuration - Avaya Ethernet Routing Switch 8300 Series Installation Manual

DC power supply fundamentals
Minimum number of 8005DC power supplies to install
To configure an Ethernet Routing Switch 8300 system, consider the total power consumption
to ensure proper system performance.
The total input power consumption of the components (modules and fan trays or cooling
modules) must not exceed the 8005DC power supply rating.
To determine the minimum number of power supplies to install for the Ethernet Routing Switch
8300 system, see

Redundant power configuration

If a chassis has a redundant power configuration and one power supply fails, the chassis
continues to operate with no interruption of service. The chassis continues to supply the same
module output power with the remaining power supplies. A trap and syslog message indicates
that the configuration is nonredundant. Avaya recommends that you operate the Ethernet
Routing Switch 8300 system in a redundant configuration at all times to ensure maximum
network performance.
Important:
A redundant power supply ensures that the system does not fail if a single power supply
fails.
If a chassis has the minimum power supply configuration and one power supply fails, the
system loses power and network connectivity.
