EVA2C12D INRUSH CURRENT

[Farid Abizeid]

Hi,

Looking at the EVA2C12D power specs,
it takes as high as 560 Amps of inrush curent
with a nominal of 8 Amps per line or 14 Amps
in failover mode.

We have noticed that when the system was totally shutdown, its built in 32 Amps circuit breakers are unable to handle such inrush current, so they trip.
We had to apply power sequentially on the disk enclosures until last powering up the HSV controllers to power it up agin.

I do understand that cold reboot of such machine is not an often task but I do
appreciate your comments.

Regards,
Farid

Farid,

are you looking at EVA5K or 8K? Although I am not providing any answers to your question just yet (as I do not have a solid one riit now)...I am currently assessing the power requirements of EV5K Vs. 8K...so I will come back to your post.

Just to clarify
The internal 32 Amps Circuit breakers are unable to hanndle the inrush current of the 2C12D.
Note that only one breaker is switched on at a time which make the inrush current more severe on one side..

More feedback is appreciated.
Thanks and regards
Farid
