HP E8491A manual Running the Resource Manager

Running the Resource Manager

When the VXI mainframe is turned on and the E8491A interface has been configured using ‘I_O Config’, the SICL iproc utility is started. This enables the resource manager to run when:

•mainframe power is cycled

•the E8491A faceplate Reset button is pressed

•activated from the ‘I_O Config’ utility

The resource manager initializes and prepares the VXI system for use.

In VXI systems with multiple E8491As (mainframes), individual mainframes can be turned off without affecting other mainframes in the system. When a mainframe is turned on, the resource manager reconfigures the mainframe.

Notice that the resource manager will only run if the iproc utility is started. Again, configuring the E8491A interface using and then closing ‘I_O Config’ starts iproc. You can manually start, stop, or verify the state of the utility as shown in Figure 2-18.
