[c-nsp] 7609 - Redundant Supervisors

[Tim Stevenson]

Hardware revision doesn't matter. It is probably a good idea to have the 
same rommon where possible but that is not mandatory.

Technically, in your situation, you could upgrade the DRAM on the sup in 
slot 2 using MEM-S2-256MB= and MEM-MSFC2-256MB= and be ok, despite the 
model # difference (2U is just a cisco PN denoting a sup2/msfc2 with 256MB 
DRAM on the SP/RP).
