Communication Manager software reset (recovery)
There are severe reset levels available to restart Communication Manager. These resets can be user
initiated with the reset system n command (where n is the reset level). They may also be automatically
initiated by the system’s software in response to certain error conditions.
A system is reset due to a loss of power, or through:
• Reset commands entered during a SAT terminal session.
• Maintenance software, from which the system can reset itself. (This process starts when certain
software and hardware errors are detected by the software.)
CAUTION:
When the system is rebooted or reset at level 2, 3, 4, or 5, every voice terminal and
attendant console feature is adversely affected. Users should be advised of services that
are lost and that, as a result, must be reactivated.
The SAT display and circuit pack LEDs indicate the progress of the recovery process.
