10 gig connectivity on our 6506-E

[broow]

we have a older WS-C6506-E we use for our Security System.

Mod Ports Card Type                              Model              Serial No.

  6    2  Supervisor Engine 720 (Hot)            WS-SUP720-3B       SAL092858HY

I would like to add a WS-X6708-10GE to provide 10 gig to a 2960s switch the new Security Servers we be place.

At present the 6506 has:

system power redundancy mode = redundant
system power total =     1153.32 Watts (27.46 Amps @ 42V)
system power used =       918.12 Watts (21.86 Amps @ 42V)
system power available =  235.20 Watts ( 5.60 Amps @ 42V)

If i move the Power supplies to a 220volt circuit  and with the present hardware, should the new

10gig card work?

You shouldn't need to change the power input to put a x6708 in the chassis.  If you are using 120volt it should still work fine as long as you have enough power on the PSUs.

Will in work in with your current configuration?  No!

The 6708 will draw about 445 watts, which you don't have available.

However, if you change from power redundancy to combined power, then it will work.

It will also work, with power redundancy, if you move to 220V.
