3800 - Redundant Power or not

Hi,

I have a couple of 3800 48G POE Switchtes (J9574A). They all have redundant power supplies.

Sometimes, if one of the power supplies is unpluged, the switch will reboot, causing a temporal outage. But then it will run fine on the remaining power supply.

Why does it reboot? Is there something faulty or do I have to change a setting?

Thank you very much and best regards,

  Wolfgang

Re: 3800 - Redundant Power or not

Are you sure each HP 3800 owns a pair of Power Supply Unit?

Can you post the output of

show system power-supply

command?

To me it looks like you have both HP 3800 backplane stacked together...and each one has just one Power Supply unit...glad to be wrong...so please provide us more details.

Thank you for your reply.

Yes.


switch# show system power supply

Power Supply status:

Member  PS#   Model     Serial      State           AC/DC  + V        Wattage   Max   
 
------- ----- --------- ----------- --------------- ----------------- --------- ------
  1       1     J9580A    TH69DMN04K  Powered          AC 120V/240V       81      1000
  1       2     J9580A    TH63DMN0DD  Powered          AC 120V/240V       89      1000
  2       1     J9580A    TH69DMN07V  Powered          AC 120V/240V       83      1000
  2       2     J9580A    TH63DMN0N5  Powered          AC 120V/240V       92      1000
 

 

Also to be clear, the switch does not turn off when unpluging one of the cables.  I just reboots (powered by the remaining cable/PS)
