7-segment display status codes and actions
NOTE: The 7-segment display shows two types of codes: Enclosure numbers and alarms.
The enclosure number is shown only as a numeric value. Alarms are shown as both an alpha
and numeric combination (for example, A3). Typically, the enclosure number and any alarms are
alternately displayed. Multiple codes can be alternately displayed one after the other if more than
one issue occurs.
If the GSI LED is amber, activate the associated drawer UID button to view any GSI error codes
on the rear display. The two UID buttons are used to select which drawer is displayed. The display
cycles a drawer pointer ("|-" points left and "-|" points right), followed by one or more GSI error
codes.
