2.1 Halting the System
To halt the system safely:
1. Back up the system files and data, if necessary.
2. Halt the system using the appropriate commands.
3. Wait for the system-halted message and the boot monitor prompt.
4. Turn the key switch (on the front panel) to the Standby position.
5. Turn the AC power switch on the system back panel off.
Caution – The system chassis power must be turned off, and the AC power
cord must remain plugged in to ensure a proper ground.
