Gateway software is fully initialized and providing service, or

Shutdown States
E_SHUT Error Shutdown — Flashes whenever a critical error condition is
encountered and the system is shutting down. Once the disk is
spun down, the display becomes steadily lit. Flashware
continues to execute. Can also be entered when:
Board tests have failed and the red LED is lit.
Flashware or software has failed to initialize and has shut
down.
A maintenance shutdown was directed and an operational
error occurs. For instance, the Faceplate and Alarm Panel
(FAC) timed out on the transition of the MFB to the
M_SHUT state.
On a running system, maintenance software detects a
condition requiring an error shutdown.
When in this state, the system can be powered down and
removed from the switch carrier for repair.
M_SHUT Maintenance Shutdown — Flashes when a technician has
directed Maintenance shutdown either by pressing the
BOOT/SHUTDOWN button, or through the SYSTEM
SHUTDOWN command on a maintenance terminal. Flashware
executes and the disk is spun down. Once the system is
completely shut down, the display becomes steadily lit.
When in this state, the system can be powered down and
removed from the switch carrier for repair.
S_SHUT Shows only if the interboard bus cable is disconnected.
Reconnecting the cable will bring the system back to the OA&M
or ASAI-E state.
