Power-Over-Ethernet Redundancy 5400R ZL2

Trying to enable power-over-ethernet redundancy - however it doesn't think that the second power supply is connected? 

 

MYSWT(config)# sh system power-supply

Power Supply Status:

PS# Model Serial State AC/DC + V Wattage
---- --------- ------------ ----------------- -------------- ---------
1 J9828A IN77G4D1SW Powered AC 120V/240V 700
2 J9828A IN77G4D0FK Powered AC 120V/240V 700

2 / 2 supply bays delivering power.
Total power: 1400 W

MYSWT(config)# sh power-over-ethernet

MYSWT(config)# power-over-ethernet redundancy full
This operation may interrupt power to some ports.

Redundancy is not supported when only one power supply unit is powered.

Is it a 6 or 12 slots chassis?

Re: Power-Over-Ethernet Redundancy 5400R ZL2

That's interesting:

 

Aruba 5412R zl2 (KB.16.05.0007, thus a not too recent software release):

 

A5412Rzl2(config)# power-over-ethernet 
 poe-reset             Use this command to reset the PoE controller to which the port belongs.
 pre-std-detect        Detect and power pre-802.3af-standard devices.
 redundancy            Set how much power is held in reserve for redundancy.
 slot                  Optional - Specify a valid powered-slot list for power threshold setting or omit to set all powered-slots.
 threshold             Set the threshold at which the system will send an excess power consumption notification trap.

Now on a VSF made of two Aruba 5406R zl2 (running the very same software version):

 

A5406Rzl2-VSF(config)# power-over-ethernet 
 poe-reset             Use this command to reset the PoE controller to which the port belongs.
 pre-std-detect        Detect and power pre-802.3af-standard devices on the specified stack members or member to set on all members
 slot                  Optional - Specify a valid powered-slot list for power threshold setting or omit to set all powered-slots.
 threshold             Set the threshold at which the system will send an excess power consumption notification trap.
 vsf                   Set PoE configuration for the specified members.

So the power-over-ethernet redudancy option seems to be not available on my Aruba 5406R zl2...and I don't think this absence is due to VSF deployment scenario (2x5406R)versus a Standalone scenario (1x5412R) since the Power Supplies PoE redundancy option should be tied, as a feature, to the chassis operation and it should be independent by VSF scenarios versus Standalone scenarios.

 

Clearly we have the maximum numbers of Power Supplies installed on both scenarios:

Side note (OT): considering you have all and only V3 zl2 Modules why not allowing v3 mode of operation only? It's a change that will require a reboot...but you will gain 40Gbps of throughput (80Gbps per Module) facing the backplane on each Aruba v3 zl2 Module actually installed...plus other features, see below:v3_mode.png

Thanks for this tip - will do! We have a few of these units, no doubt we're running them all in this mode!
