CISCO 4510E Power Setup

[Joshua Straughn]

We have recently purchased a new 4510R+E to replace our Core Switch.  The unit has two auto switching multiple input power supplies.  My question is this, We have two 220v outlets available that are not on redundant power, and we have two 110v outlets that are on redundant power.  Would I be able to connect one power supply to the 220v outlets and one power supply to the 110v outlets or do both power supplies need to be connected to the same voltage outlets?

For clarification I would like it setup like this:

PSU 1:  Input 1=220v  input 2=220v

PSU 2: Input 1=110v input 2=110v

Any help here is greatly appreciated.

Hi Joshua

Look at this link.
http://www.cisco.com/c/en/us/products/collateral/switches/catalyst-4500-series-switches/q-and-a-c67-732778.html

Cisco are instructing you NOT to mix 220V & 110V in the same chassis

Q. Can I use the AC-input power supply in mixed-voltage (110 VAC or 220 VAC) configurations?

A. The AC-input power supply should not be used in mixed-voltage configurations. All the inputs in a chassis must be at the same voltage (110 VAC or 220 VAC).
