User Diagnostics
Video Display Diagnostics
The two modes of the user diagnostics are video display mode and front panel mode. Either mode
can be selected at any time before the POST diagnostic tests finish.
• Front Panel Mode: Press either “arrow” pushbutton (
18 or 19 ). The description of
front panel display diagnostics begins on page 86.
• Video Display Mode: Enter either a “V” or “v” from a terminal connected to Port 1.
The PortServer video display diagnostics are controlled from a terminal (or PC
with terminal emulation software) connected to Port 1. This terminal must be set
to 9600 baud, 8 data bits, 1 stop bit, and no parity.
There are eight tests that can be selected. These tests perform diagnostic checks on hardware
sections of the PortServer.
If “V” is pressed to enter Video display mode, a startup screen appears. The screen displays test
information, and waits for user input.
To start any test, press the appropriate test number. See Basic Test Descriptions on page 86 for
information on the individual tests.
