Maintenance Strategy
Considerations
■ Power interruptions of less than 100 ms usually do not affect the system.
■ Warm starts may cause telephones without incoming calls to ring.
Cold Start (Restart)
If you need to restart the system, cold start (Restart) is recommended.
Restart drops all calls but saves system programming.
To perform a cold start, select
Restart as follows:
Console Procedure Menu→
SysProgram→Exit→System→ →Yes
PC Procedure → → → →
Considerations
■ A cold start (Restart) occurs automatically after a power interruption of
more than one second.
■ A cold start (Restart) does not blank out the screen on an MLX-20L
telephone until the cold start is completed.
■ A cold start (Restart) can cause extensions with the Extension Status
feature to lose their toll restrictions.

Programming

Processor Problems’’ in Chapter 4.
