Things to know - Seven-segment display for the ESMs on
the drive trays
During normal operation, the tray ID display on each ESM shows 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.
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.
