Diagnostics

The server provides the self-check diagnostics function for some components. If a fault occurs in a component, the server can diagnose the component to detect the fault.

For this server, CPU modules and IO modules can be diagnosed all together.

To diagnose a component with the NEC ESMPRO Manager, use the [Maintenance] tree of the component in the data viewer. Open the tree of the component to be diagnosed and select the [Maintenance] tree.

To diagnose of a component with the Server Maintenance Utility, use the component screens of the Server Maintenance Utility.

The table below shows the potential cases in which a component is to be diagnosed.

Remote:	Executable from remote management PC by using NEC ESMPRO Manager

IMPORTANT:

Diagnostics operations are performed to IO modules. When IO modules are diagnosed, CPU modules will be diagnosed as well. CPU modules cannot be diagnosed individually.

The system diagnostics cannot be performed while collecting dump or updating firmware. Wait until such processing is finished to perform the diagnostics.
