[c-nsp] DC Powered Switch

[Ivan]

I am after a basic switch but it need to be DC powered.  Something like 
a 2960 would be more than good enough.  Would the lowest cost Cisco 
option be the ME-3400E-24TS-M with DC supplies?  Requirements are layer 
2, ~24 ports and dc power.

I did get a quote for one of these and the first DC power supply was 
listed as ME34X-PWR-DC and the second as ME34X-PWR-DC-R, but the second 
one costs 3 x as much - is there something special about the second PS 
in this model?

Thanks

Ivan
