system auxiliary power mode

Hello.

Someone can explain me what is "system auxiliary power mode"?

I've searched on documentation but I didn't find it.

I don't think that is redundancy, because from "show power redundancy-mode" command I can see:

cat6513#sh power redundancy-mode 

system power redundancy mode = redundant

 

But from "show power" command:

 

system auxiliary power mode = off

system auxiliary power redundancy operationally = non-redundant

system primary connector power limit =   5880.00 Watts (140.00 Amps @ 42V)

system auxiliary connector power limit = 0 Watt

system primary power used =              2766.96 Watts (65.88 Amps @ 42V)

system auxiliary power used =            0 Watt

 

What is this?

Thanks

Daniele

Hello, I have this question too. I have switch WS-C6509-E, after command "show power", i receive this text:

system power redundancy mode = redundant
system power total = 5771.64 Watts (137.42 Amps @ 42V)
system power used = 3540.18 Watts (84.29 Amps @ 42V)
system power available = 2231.46 Watts (53.13 Amps @ 42V)

system auxiliary power mode = off

system primary connector power limit = 10920.00 Watts (260.00 Amps @ 42V)

system primary power used = 3540.18 Watts (84.29 Amps @ 42V)
system auxiliary power used = 0 Watt

I don't know what these lines mean (system auxiliary power mode = off
system auxiliary power redundancy operationally = non-redundant). This question has not received an answer, but I hope that after all someone will tell where the answer.

Hello,

 

--> system auxiliary power mode = off

 

This means you don't have a secondary power unit installed and operational. The output of:

 

sh power redundancy-mode

system power redundancy mode = redundant

 

just displays the redundancy mode, where 'redundant' is the default. You can also configure 'combined'.  Both primary and auxiliary units can be configured for redundant mode or combined mode. The difference between both modes is explained below:

 

Redundant Mode

 

When running in Redundant Mode, each power supply provides approximately 50% of its capacity to the chassis. In the event of a failure, the unaffected power supply will then provide 100% of its capacity and an alert will be generated. As there was enough to power the chassis ahead of time, there is no interruption to service in this configuration. This is also the default and recommended way to configure power supplies.

 

Combined Mode

 

In combined mode, each power supply provides approximately 83% of its capacity to the chassis. This allows for greater utilisation of the power supplies and potentially increased PoE densities.

 

Hope that helps...

 

Thank you for your answer. You are really hoped me.
