LCD Status Messages
The system's control panel LCD provides status messages to signify when the
system is operating correctly or when the system needs attention.
The LCD lights blue to indicate a normal operating condition, and lights
amber to indicate an error condition. The LCD scrolls a message that
includes a status code followed by descriptive text. Table 1-5 lists the LCD
status messages that can occur and the probable cause for each message. The
LCD messages refer to events recorded in the System Event Log (SEL). For
information on the SEL and configuring system management settings, see
the systems management software documentation.
