I have a stack of 2 WS-C3750X-12S-E switches running C3750E-UNIVERSALK9-M Version 12.2(55)SE8.
If I insert a C3KX-NM-10GT (Two 10GB-T ports) network module in either stack member it logs "%PLATFORM-4-FRULINK_UNSUPPORTED: Unsupported FRULink 10G NS module inserted in Switch 1. Remove the unsupported module and insert a supported FRULink module." If I remove said module then the stack member crashes. These modules are listed on the 3750X datasheet so I thought they should work. Any idea what the problem is?
Also one stack member with Model revision number: A0 will recognise GLC-T SPFs but the other stack member which was recently replaced and has Model revision number: R0 does not recongnise these SFPs. They don't show up on show inventory if inserted in the second stack member. Fibre SFPs show up OK though. Any ideas?
