### MP-551 Too many soft rate groups

There are more rate groups than the system can handle. May indicate an MP operating system software failure.

On an MP-30 system, a RAM chip is bad.

On an SMP-400 system, either the DRAM SIMM on the processor board or the processor board itself has failed.

Refer to MP Error Codes for additional information.
