This message indicates that the module is not responding to the supervisor engine requests over the inband communication channel. This error can be caused by the following reasons: * the supervisor engine being excessively busy * spanning tree protocol loops * ACLs and QoS policers throttlingdropping traffic over the inband communications channel * port ASIC synchronization problems * Switch Fabric Module problem
The most common reason, is insufficient insertion force, which can leave only certain pins touching or all which are only partially making contact.
You may want try to reseat the module 1 and make sure that is completely inserted in the chassis. You may also want to try to upgrade to the later 7.x code if you are hitting one/more of the following bugs:
