How concerned should I be about the HW and FW revisions?  2.2 to 4.3 seems pretty far apart.

Here are two CEF720 24 port 1000mb SFP   WS-X6724-SFP  modules.  One is our current running and the other is from used market for  lab testing.

Mod MAC addresses                             Hw    Fw                  Sw                   Status

0013.1972.6828 to 0013.1972.683f   2.2   12.2(14r)S5  12.2(33)SXI7 Ok

8843.e1aa.a5e8 to 8843.e1aa.a5ff    4.3   12.2(18r)S1  12.2(33)SXI7 Ok

I guess I could ask TAC what the revisions changed or fixed.

Thanks for any help.
