LAN Diagnostics
For fun, please press the Page button and enter the following menu page: 7431. This will take you to
the DIAG->System Info->LAN Status menu.
This graphically shows the communication between the components you just defined. Just as a side
note, blinking red lines are bad and mean communication is not occurring. This is a great menu to
troubleshoot communication errors.
Errors
The MVS system has a sophisticated internal diagnostic system. These diagnostics start from power-up
and run continuously while power is applied. If MVS detects an error in the system, you will see large
red letters spelling ERROR in the menu display.
