Display Messages
The control panel display can show messages of up to four lines of 20 characters each.
Many of these messages and their functions are described next. Those displays that are
described in other sections are cross-referenced here.
Power-On Self-Test Screen
When power is first applied to the module, a series of power-on self-test (POST)
diagnostics are performed. During POST execution, the model number of the module,
the current date and time, the firmware revision, and the status or result of the test in
progress are displayed on the control panel, as shown in Figure 6-3.
