The snoop arbiter on the VXR midplane fails to recognize the NPE-200 when Port Adapters are installed in the chassis. This results in the system failing to boot Cisco IOS and only booting to a ROMMON prompt. This problem does not occur when Port Adapters are not installed in the system.
Note:?This problem does not exist on any other NPE/VXR combinations. It is only a problem with the NPE-200 on a VXR Chassis.
A change was made to the snoop arbiter on the VXR midplane which causes the NPE-200 not be recognized. This results in the system not booting to Cisco IOS but instead booting to a ROMMON prompt. This problem occurs on the 7204VXR with product number 73-3905-07 and 7206VXR with product number 73-3223-09. Any version of the product number not listed will not experience this problem. The problem surfaces when Port Adapters are installed in the system. If there are no Port Adapters installed, the problem will not occur.
When a Cisco 7204VXR or Cisco 7206VXR with the new snoop arbiter has an NPE-200 and Port Adapters installed, the system will only boot to a ROMMON prompt. An example ROMMON prompt is below:
rommon>
To resolve this issue, a new snoop arbiter is now being used in the latest version of the chassis. This new snoop arbiter will recognize the NPE-200 when Port Adapters are installed in the chassis. The new product numbers for the Cisco 7204VXR are 800-04766-09 and 73-3905-08. The new product numbers for the Cisco 7206VXR are 800-04667-09 and 73-3223-10.
In order to resolve this issue, replace the chassis (Cisco 7204VXR or Cisco 7206VXR) through the return materials authorization (RMA) process. Please code the RMA request as ARFN (Administrative Request - Field Notice).
