About one minute after the IGX-URM comes up, the IGX8400 registers an IPC failure and declares the URM card "failed".
This anomaly is caused by an uninitialized field which causes IPC communications to fail.
Besides loss of services through the affected IGX-URM, the network engineer will observe that the IGX-URM status (issuing dspcds) is failed and the event log (issuing dsplog) indicated removal of the URM.
The following is a part of the dspcds command output showing a failed IGX-URM:
