We occasional lose a switch and it's usually because of the power supply. As far as access layer switches are concerned, I was wondering if there is a different model for say PoE compared to a switch that is not PoE. Or 48 port vs. 24 port. Or, 370 vs. 3560.


Thanks, Pat.

For smaller 1RU fixed switches, there isn't much of choice of power supplies, you can add more power for POE vs non-POE switches, but that is all you can do. It is not like the modular switches with many choices of PSUs.

If you lose PSU occasionaly in spesific location, I would have an electrician check the power sources and test for power fluctuation for a period of time.

Reza,


so,the same PS that works in a PoE, switch WS-C3560-24PS-S will  work for a WS-C3560-48TS-S? And will if also work in a WS-C3750-48TS-S?


I would like to order just one back-up power supply if possible to cover all models in the event one goes bad


Thanks, Pat.
