Hard-Drive Indicator Codes
The hard-drive carriers have two indicators—the drive-activity indicator and
the drive-status indicator. See Figure 1-2. In RAID configurations, the drive-
status indicator lights to indicate the status of the drive. In non-RAID
configurations, only the drive-activity indicator lights; the drive-status
indicator is off.

and system error messages.
The LCD lights during normal system
operation. Both the systems management
software and the identification buttons
located on the front and back of the
system can cause the LCD to flash blue
to identify a particular system.
The LCD lights amber when the system
needs attention, and the LCD panel
displays an error code followed by
descriptive text.
NOTE: If the system is connected to AC
power and an error has been detected, the
LCD lights amber regardless of whether
the system has been powered on.
