Check and Clear of MTBF Information
The MTBF information of a component can be viewed or cleared (initialized).
NEC Express5800/ft series manages the MTBF (mean time between failure) of each component. If
a fault occurs in a component, the NEC Express5800/ft series calculates the MTBF of the
component again. If the calculated value is lower than the pre-defined threshold, the NEC
Express5800/ft series disables the component to be used.
Contact your maintenance personnel if such a symptom as above occurs.
IMPORTANT:
A disabled component with the MTBF lower than the threshold can be
forcibly enabled by clearing the MTBF. However, contact your maintenance personnel for the
forced use of such a component.
To clear the MTBF information of a component with NEC ESMPRO Manager, use the
[Maintenance] tree of the component of the [ft] tree of the DataViewer. Open the tree of the
component whose MTBF information is to be cleared and select the [Maintenance] tree.
To clear the MTBF information of a component with the ft server utility, use the utility screen of the
component. The table below shows the potential cases in which the MTBF information of a
component is to be cleared. Contact your maintenance personnel for clearing MTBF information.
MTBF clear
Component
Remote Local
CPU Module
To start the module forcibly after
replacing a module or if MTBF became
lower than the threshold due to
malfunction and disabled the module.
Executable in the following module
state (this can be viewed on manager
screen):
•
Broken
MTBF is lower than the threshold.
To start the module forcibly after replacing
a module or if MTBF became lower than
the threshold due to malfunction and
disabled the module.
Executable in the following module state:
•
The amber LED is on.
•
The event indicating that MTBF is lower
than the threshold is registered in the
event log.
PCI Module
Same as above
Same as above
Ethernet
Adapter
To start the module/component forcibly
after replacing a module or if MTBF
became lower than the threshold due
to malfunction and disabled the
module/component.
Executable in the following module
state (this can be viewed on manager
screen):
Broken
MTBF is lower than the threshold.
To start the module/component forcibly
after replacing a module or if MTBF
became lower than the threshold due to
malfunction and disabled the
module/component.
Executable in the following module state
(this can be viewed on manager screen):
•
The amber LED is on.
•
The event indicating that MTBF is lower
than the threshold is registered in the
event log.
SCSI Adapter

IMPORTANT:
You can also clear MTBF information for the PCI module, Ethernet Adapter and
SCSI Adapter by unplugging and plugging the live wire of the PCI module.
