Without going to much into it, if you connect both sources of power, you are in fact supplying the switch with 2 sources of power simulataneously. There is no power 'switching' (excuse the pun) mechanism on switch by itself.
You'll probably blow up the switch!

Has anyone of you guys tried to connect both? The manuals says not to do it. If this works you'll have a very cheap redundant power solution, of course Cisco doesn't like it and will say it's impossible.... ;-) Any experience connecting the AC to wall power and DC with a external power supply? grtz, Koen ----------------------- Cleanliness is next to impossible.
