"N+1" nominally means you're connected to the same UPS system/complex, but each of your feed is on a different module.  
Your other leg will be diverse from a failure in that module, or downstream PDU/panel work fed by that module.  A 
common failure mode in the UPS system itself hosting the different modules can knock out both of your circuits.  It 
sounds like this is how you are configured presently.

"2N" generally means you're connected to completely different UPS system/complex and corresponding distribution systems 
for each of your circuit.  This is ideal configuration for most critical loads.
