Switching

In the next couple weekends I'm planning to add 2 CISCO UCS 6248UP Interconnects to 6509 Core Switches via 10G links.Is there any impact anticipated?  It's a production environment and no loss of up-time is acceptable.

I have a stack with 4 2960S and 4 uplinks to the core. I was wondering if it is better to connect one uplink for each switch, or just connect two switches, thus the two members (2&4) not directly connected.ThanksDomenico
