Cpu Modules - NEC Express5800 320La System Configuration Manual

CPU Modules

Your server includes two CPU modules that you may monitor using the ft
Server Utility. When you select a CPU module, six CPU maintenance functions
are displayed: MTBF Clear, Start/Stop, Module Diagnostic, Firmware Update,
Board Switch and Dump. Module Diagnostic and Board Switch are not
supported. This section provides procedures for viewing and using these
functions.
MTBF Information Clear
The MTBF (Mean-Time-Between-Failures) information of a CPU Module may
be cleared (initialized). Your server manages the MTBF of each component.
Each time a fault occurs in a component in a CPU module, the module
recalculates the MTBF of the component. If the calculated value is lower than
the pre-defined threshold, the system performs one of the following predefined
three functions:
!
Use Threshold: MTBF is calculated when a fault occurs. If calculated
MTBF is below the set threshold value, the device is stopped.
!
Never Restart: The device is stopped whenever a fault occurs.
!
Always Restart: The device is rebooted whenever a fault occurs.
Note:
threshold, can be forcibly enabled by clearing the MTBF.
Procedure:
To clear the MTBF information of the CPU module, click on the MTBF button
displayed in the ft Server Utility CPU module screen.
