Minimum number of power supplies required
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) must not exceed the output power rating of the power supply. To
determine the number of power supplies to install for the Ethernet Routing Switch 8300 system,
see Table 1: Recommended 8301AC or 8302AC power supplies
Redundant power configuration
If a chassis has a redundant power configuration and a power supply fails, the chassis
continues to operate without any interruption of service. The chassis continues to supply the
same module output power with the remaining power supplies. If a chassis has the minimum
power supply configuration and one power supply fails, the system loses power and network
connectivity. A trap and syslog message indicates that the configuration is nonredundant.
Avaya recommends to operate the Ethernet Routing Switch 8300 system in a redundant
configuration only to ensure a maximum network uptime.
