sfp-10g-lrm dropping link

I have 2 switches WS-c2960s-24PD-L one of the SFP ports on both are connected to other switches running the 10g-LRM  SFP modules. The two 2960 in question are connected by 1000BaseSX SFP modules. When i try to replace the !gigs with the 10gigs (on both ends) the config is the same on both ends. when i swap out the sfp the link will come up for a few mins then drop. i can do a shut/ noshut on the interface and it will comeback then go down again. Can any one give me some idias to try This link is working fine with the 1Gig SFP.

Re: sfp-10g-lrm dropping link

What is the distance of the fibre? If the original was running on GLC-SX-MM then you should've replaced them with SFP-10G-SR and not LRM.
