Things to know - Display sequence code definitions
During normal operation, the tray ID display on each controller canister shows the controller-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. The category code may
be followed by a dash + and a "CF" followed by one of the component location codes described in
Things to know - Lock-down codes
on page 129.
