Things to Know – Seven-Segment Display for the Drive Trays
During normal operation, the tray ID display on each ESM displays the drive tray ID. The Diagnostic LED
(lower-digit decimal point) comes on when the display is used for diagnostic codes and goes off when the display is
used to show the tray ID.
NOTE If a power-on or reset occurs, the Diagnostic LED, the Heartbeat LED (upper-digit decimal point), and all
seven segments of both digits come on. The Diagnostic LED remains on until the drive tray ID appears.
