i have a problem with SFP ports.
i have 15 fiber connection from 7250 switches to 6610-24f using cisco 1 Gb SFPs and all connections are work but i want to replace this 6610 with two 7250 but when i replace it no connection work at all ( the ports don't bring up) ,
Note : i dont have any config in any switch of them and i use the same cables and SFPs.
i tried to no shut the ports but no work too.
can any one give a solution?

The SFP+ units may not work, but regular SFPs are a relatively open standard.
It is highly recommended to use Brocade ones for support, but I see no reason Cisco 1G SFPs would not work.
I do NOT have a 7250 in my environment, but looking at a 7450-48F, I have to wonder if it is configured for 10 Gigabit or 1 Gigabit/sec

If this is the case, you can probably set the speed to a standard SFP speed...
