Routine Maintenance
System Reset
The controller can be reset by:
• pressing the Reset button on the front panel
• using the RESTART_SYSTEM command from the Maintenance terminal
• powering the controller down then back up
When the system is reset, it stops all call processing activity, runs
initialization tests. It also reloads software from the external CompactFlash
card if it detects that the card was removed, and then reinserted.
System Shutdown
A System Shutdown is required before moving the controller or replacing
hardware in it. Shutdown terminates all calls (except calls between IP
phones or calls carried on IP trunks) and disables the serial and IP
interfaces.
To shut down the system:
1. Log into the Maintenance Terminal (serial connection only) and begin
a Maintenance session.
2. Press the following softkeys:
RE_START
SHUTDOWN
ENTER
After entering the command, wait for this message to display: "System
shutdown complete." Then, unplug the power cord.
To return the system to service:
• Unplug it and plug it in again, or press the Reset button.
CAUTION:Resetting the system drops all calls in progress. If a
reset is required, do it during periods of low or no call traffic.
CAUTION:The following procedure takes the system out of
service.
