Cisco Nexus 9508 User Manual

n+n redundancy mode
This mode allocates half of the power to available power and the other half to reserve power. You must
use a different power source for the active and reserve power sources so that if the power source used
for active power fails, the other power source used for the reserve power can provide power for the
switch.
For example, if the switch requires 4.0 kW of power, the switch has four power supplies that each
output 3 kW. If you have two power grids, you use grid A to power two 3-kW power supplies that
provide the available power for the switch and you use grid B to power the other two 3-kW power
supplies that provide the reserve power in case grid A fails.
Power Mode Configuration Guidelines
The amounts of available and reserve power depend on the power redundancy mode that you specify and the
number of power supplies installed in the switch. For each redundancy mode, consider the following:
