MAINTENANCE
Restarting the System
The system automatically warm starts after power is restored. (The system’s
maintenance software may restart the system under certain self-detected
error conditions. ) There are two types of restart: cold and warm.
A Cold Start and limited cold start (which takes about 4 to 5 minutes) causes
the system to check all slots for valid CP types and assign default
translations to all ports except auxiliary trunk ports. Current translations are
not retained. This means that all calls in progress are dropped.
A Warm Start (which takes about 3 minutes) causes the system to check all
slots for valid CP types but does not assign default translations. Current
translations are retained, but all call status information is cleared. This
means that all calls in progress are dropped.
During a Cold or Warm Start, the SAT lists the version of the firmware loaded
in the CPU/Memory CP, lists all CPs in the system, by cabinet, and indicates
any invalid types/versions detected. When the Cold or Warm Start is
complete, the green LED on all CPs (except the CPU/Memory and Auxiliary
Trunk) should be lighted and the amber LED on the Service Circuit should be
flashing or steady. All red LEDs should be dark.
The system can also be restarted by entering commands at the SAT. Follow
these steps to manually restart the system from the SAT:
1.
Confirm that the SAT is properly connected to the CPU/Memory CP
administration port.
2. If the SAT has a selectable baud rate, set it to 1200 baud.
3. Be sure that transmission parity is set to none and the parity bit is
set to space (0).
4. Turn the terminal on, and press the carriage return key once or
twice. On most terminals, this key is <RETURN> or <ENTER>.

5. Obtain the password from the System Administrator. Enter the
password, and press <RETURN>.
