Set MTBF Type
In this section, you can specify operations to be performed when failures occur on CPU or PCI
modules.
NEC Express5800/ft series manages the MTBF (mean time between failure) of hardware
components. If a fault occurs on a CPU or PCI module, the NEC Express5800/ft series calculates
the MTBF again. If the calculated value is lower than the pre-defined threshold, the NEC
Express5800/ft series disables the applicable module. Setting MTBF type for each module allows
you to restart or stop using the module without calculating the threshold when failures occur.
MTBF type description
“Use Threshold” (default)........If a failure occurs, the MTBF is calculated and the module is
stopped when the value becomes lower than the threshold.
“Never Restart”........................If a failure occurs, the module is stopped regardless of the MTBF.
“Always Restart” .....................If a failure occurs, the module is restarted regardless of the MTBF.
The default setting is “Use Threshold”.
IMPORTANT:
By clearing the MTBF, you can forcefully enable the component which has been
disabled because the MTBF value became lower than the threshold. Contact your
maintenance personnel if you want to enable the component forcefully.
If you set “Always Restart” for the MTBF type, the module may continue restarting
when a failure occurs. It is recommended to set “Use Threshold” for the MTBF type.
The module will be stopped automatically when it fails to restart repeatedly.
When the module is replaced, the MTBF type returns to the default setting “Use
Threshold”.
Procedure for setting MTBF type
1. From the [Start] menu, select [All Programs] – [NEC ESMPRO Agent] and then click [ft
server utility].
The [ft server utility] dialog box appears.
2. Select the module of which you want to change the MTBF type from the [CPU Module] or
[PCI module] on the [FT server] tree on the left pane. Then, select the MTBF type on the
[MTBF Type] on the right pane and click [Apply].
The MTBF type of the selected module will be changed.
IMPORTANT:
The MTBF type can be set for each module. To change the type of both PCI modules,
perform the process above for each module.
