Changing power mode on a 6500

We have two 6500s. One is running in power redundant mode and the other is running in combined mode.

We need to change the one running in combined mode to redundant mode to ensure it can run ok on one supply if needed but I have a couple of questions.....

1. Assuming that we are not oversubscribed on the power allocated, does changing the mode cause any disruption?

2. The switch running in combined mode seems to have allocated some power for an "Inline Local-Pwr-Pool" which is not allocated

    on the switch running in redundant mode (see attached). Does anyone know if this allocation will be needed if we change the power mode?

Hello,

Please check the following inline

1. Assuming that we are not oversubscribed on the power allocated, does changing the mode cause any disruption?

Ans:--No it shouldnot impact

2. The switch running in combined mode seems to have allocated some power for an "Inline Local-Pwr-Pool" which is not allocated on the switch running in redundant mode (see attached). Does anyone  know if this allocation will be needed if we change the power mode?

The reason for "Inline Local-Pwr-Pool" not getting allocated in redundant mode is because of unavilibility of power.

system power redundancy mode = redundant

system power total =     2671.20 Watts (63.60 Amps @ 42V)

system power used =      2668.26 Watts (63.53 Amps @ 42V)

system power available =    2.94 Watts ( 0.07 Amps @ 42V)<<<<<<<<<<<<<<<<<<<<<<

Compared to

sw02>sh power

system power redundancy mode = combined

system power total =     4452.00 Watts (106.00 Amps @ 42V)

system power used =      2769.48 Watts (65.94 Amps @ 42V)

system power available = 1682.52 Watts (40.06 Amps @ 42V)<<<<<<<<<<<<<<<<<<<<<<<<<

Hope this helps to clarify
