Interface is up.  Both host and switch see it as up, but no packets passed.  Tried untagged on default vlan1 with the same issue.  Tried this on two 7024 switches to rule out the switch, and tried two 10GbE modules to rule out the module. Possible I have two broken ones, but very unlikely.  No errors reported from the sh tech. Link up at 10Gbps, hence I was wondering whether the 7024 only supports those modules for switch uplink and not for hosts.  Any ideas?  The docs specify the CX4 modules are ONLY for stacking, but the 10GbE SFP+ modules can be used for stacking OR general ethernet.

we have two adapters patched in. te1/1/1 is 1.61.1.31 and te1/1/2 is 1.61.1.32

If I plug these adapters together together back to back using the same cable, they can ping each other.

Via the module, no dice.  here is the sanitised config:

From a show tech I can also see the following. Is this normal or are my ports still configured in a stack (these switches were once stacked):

Stack Ports:

Te1/1/2          Ethernet   Ethernet   Link Up      10

Te1/1/2          0      0          0          0      0          0

Can't physically unpatch it from here, but if I disable te1/1/1 I still can't ping the host in te1/1/2 from another host.

Haven't tried disabling one port. The servers were both on a vlan before but I removed this to default to vlan1 for simplicity as everything was telling me it was a vlan issue.  

Thanks for coming back to me daniel.  Its a real head sctratcher this one.  

One host (1.61.1.31) is in te1/1/1 and the other (1.61.1.32) in te1/1/2 with no vlan, all counters at zero, and no arp entries on either of these ports.

Switch config couldn't be simpler, hence I asked whether the cable was supported on the 7024 module.  Port says its up at 10Mbps but no packets, hence no arp observations.

Apologies, I meant 10Gbps
