VNX5300 DPE Power Supply

Hello,

Many Thanks for your answer and for your valuable support.

Best Regards,

Hello,

Another question please:

As I understand that VNX5300 Power Supplies A & B on DPE (Disk Processor Enclosure) are fully redundant and I need to replace both SPS A and SPS B, is it OK to replace one SPS at a time and by this way there will be no disruption for the full Array?

Thank you again for your help.

Best Regards,

Hello OURHOUD IT ADMIN,

Here is a link to a youtube video that shows how to replace SPS. https://dell.to/3pFqisY

Hi Josh,

Both SPS are faulty so could you confirm that I can replace one SPS at a time in order to avoid disruption?

Thank you again.

Why are you needing to replace both of them if they are working?

Hello,

Yes I've already seen the video. My question was just to be sure I can replace the SPS while the system is running so that no disruption can occur.

Thank you again for your time.

Best Regards,

If they are both faulty then we can’t say for sure it will stay up when one is removed. If they were both healthy then yes you could not have downtime replacing them one at a time.

Hi Josh,

just to give you the accurate information:

SPS B has the LED "SPS fault" is On (Amber) and LED "SPS no battery" On (Amber).

SPS A has only LED "SPS no battery" on (Amber).

As the DPE is directly connected to both SPS and still running (both LED on Power Supply A & B are green) so I understand that the SPS A and SPS B are feeding the DPE and that we can disconnect one SPS with no issues right?

Thanks again.

Josh,

Sorry again:

I forget to precise that "SPS Power" LED on both SPS (A & B) are OFF but the DPE is OK 

"SPS Battery"  LED is also OFF on both SPS (A & B)

as Power supply LEDs on DPE are both Green so I understand that we can proceed to replace SPS B and then SPS A (one at time).

Thank you.
