11.4 TAKING THE LAN OUT OF SERVICE
Use the Courtesy Down command to take the LAN subsystem out of service. The Courtesy Down
command does the following:
- Takes the digital networking hardware and software out of service without interrupting any activity
in progress or causing random errors.
- Blocks any new digital networking activities.
- Waits for all activities in progress to be completed, such as background message transfers and
real-time name plays, before taking the hardware and software out of service.
- Displays progress messages while waiting for any background message transfers or real-time names
to complete.
Use the Courtesy Up command to bring the LAN subsystem back into service. The Courtesy Down
condition is maintained across a system reload, restart, or power cycle. Only a Courtesy Up command
can clear the Courtesy Down condition.
. The Shutdown command can be used to put the message server in an offline mode without
disabling the LAN subsystem. Refer to the Maintenance Command chapter, System Service Mode
Commands section in this volume.
