MS390 Power Supply

[Eddie01]

Hi,

I have a site that requested the MS390 with redundant power supplies, do they come with out of box with both power supplies.

Negatory.  You need to order the second power supply.  See here:

Thanks

@Eddie01 remember that the MS390s can share power so one power supply can power multiple switches (as long as there is hardly any PoE load).  We have Cisco 3850 stacks where we don't have Meraki and for a stack of 4 switches we'd have 5 power supplies in total and never needed more.

[Eddie01]

So the MS390 can support power stacking?

[cmr]

Yes, up to 4x switches can share power.  It hasn't been the most reliable in v14 firmware, but is enabled by default in v15

Perfect!! Thanks for the heads up

Can I use the same install procedure as the catalyst? see link below
