This function has two display modes: "hardware status display mode" and "application
status display mode".
Status display mode
Hardware status display mode
Application status display mode
The status display mode can be configured in the RAS Setup window. The default factory-
shipped setting is the hardware status display mode.
For information about how to use the RAS Setup window, see "3.1.3 Using the RAS
Setup window".
Note that if the hardware status is normal and there is no application status code to display,
the status display digital LEDs are all off.
Figure 4-13 shows an example of what is displayed in the hardware status display mode.
Dotted lines in Figure 4-13 denote the respective display modes, and the thick line denotes
the transition of the state of the status display digital LEDs.
