Current Status of Temperature, Voltage and Fan Sensors

Some modes are equipped with temperature/voltage/fan sensors that do not have information on status, current values, rpm, threshold etc. Therefore, if you view such a sensor on NEC ESMPRO Manager, it may be displayed as follows:

„The status becomes “Unknown” (grayed out) on the data viewer.

„The current value or rpm becomes “Unknown” on data viewer.

Even if the sensor is displayed like stated above, it is monitoring the server.



Actions to Take When Temperature/Voltage Error Occurs on CPU/PCI Modules

At the time when a temperature or voltage error occurs on CPU/PCI module (CPU/IO module), necessary actions will differ depending on its status as shown below. You can check the status of each module from the data viewer of NEC ESMPRO Manager or Server Maintenance Utility.

 

Status

Actions

 

 

Duplex

Stop the failed CPU/PCI module (CPU/IO module).

 

 

Simplex

Shut down the system.

 

 

 

 

 

TIPS:

„If the status is “Empty Absent,” the module is not mounted. Sensor monitoring is not conducted.

„If disks are mounted on PCI modules (IO modules), the status of both modules is “Simplex” while the disks are mirrored. Temperature or voltage error occurring during disk mirroring will result in the system to shut down.





CPU Information

In [CPU Information] of Data Viewer’s system tree, the external clock is listed as “Unknown.”



When [ft] Tree Appears on Date Viewer in an Incorrect Manner

If you open a Data Viewer immediately after the system starts up, the tree or the state of a Data Viewer may not be displayed correctly due to high load of the system. In about 20 minutes after the system startup, when a pop-up message (below) which prompts you to reconstruct a Data Viewer appears, click [OK]. The Data Viewer will be reconstructed and the tree and the status will be displayed correctly. If the [ft] tree is not displayed, delete the icon and register the server again by using the NEC ESMPRO Manager.



Floppy Disk Drive Information

If you add or delete floppy disk drive connected with USB while the system is running, the drive information under the [I/O Device] in the data viewer will be updated at the next system startup.
