are you sure that its supported? lx4 == wwdm optic == 4x2.5gbps channels using wideband muxing.
additionally, when looking at datasheets for x2 and sfp+ modules, one will see that lx4 optic mentions 4 lanes, launching in the 1300nm space and a separate pluggable for x2-10gb-lrm. sfp+ only mentions single lane in 1310nm space. i dont believe the two are compatible. would suggest looking at x2-10gb-lrm= for compatibility. regards, q. -= sent via ipad. please excuse brevity, spelling, and grammar =- On Oct 5, 2011, at 11:21, "ci...@entrap.de" <ci...@entrap.de> wrote: > Greetings, > > I have a 6509 with an X6716-10GE Card equipped with Cisco X2-10GB-LX4 10GE > modules and a Cisco 2960S-48TD-L Switch with two Cisco SFP-10G-LRM > modules. > > Right now I am not able to get an active link between these X2 and SFP > modules, it stays down/down (notconnected).
