Problem/Solution
POST has detected the processors installed in the Netserver are not
the same type or speed.
To correct this:
1. Ensure both processors in the Netserver have the same
product code, which should include the type, heat sink, and
speed.
2. If not, replace one or both to ensure both are the same
product code. Contact your service representative.
This problem must be corrected to avoid possible malfunction
or reliability problems.
