[c-nsp] No Link between SFP-10G-LRM and X2-10GB-LX4?

[Chuck Church]

I believe LX4 uses multiple wavelengths.  This seems to confirm it.  I don't
think you can mix those with anything else.

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). I instantly get a link when
connecting X2 to X2 or SFP+ to SFP+ Module. I tried nonegotiate but this
didn't help.. The 6509 runs IOS 12.2(33)SXI7, the 2960 IOS 12.2(55)SE3.
Cisco says these modules are compatible to each other..

Has anyone seen this before? Any hints or ideas?

Thanks,
Holger
