Power-down Procedures
Powering Down the Control Node
1. End any customer data entry sessions.
2. If you don’t have an up-to-date DATA SAVE on RSD,
perform a DATA SAVE to RSD (see page 164).
3. Hold down PANEL ENABLE and press ACTIVITY
FREEZE ON.
4. (Redundant systems only) Enter the PARTITION
command from the active plane and then from the
inactive plane.
5. (Redundant systems only) Enter the FILE STAT REDUN
command from the active plane and then from the
inactive plane. Both planes should be ISOLATED (see
Table 25 on page 125 if they are not).
6. Enter the DBMS STAT command. The DBMS initialized
flag should be ON.
7. Enter the VOL DISMOUNT SYSUSER command (if your
system is redundant, enter the command first from the
inactive plane and then from the active plane).
8. When the system confirms that SYSUSER is
dismounted, set the power switch on the power
distribution units at the rear of the main control cabinet to
“0” (OFF).
9. Disconnect the power cords from the power source.
