Standby position
Caution – Be sure to turn the system control keyswitch to the Standby position
before handling any internal components. Otherwise, it is possible for an operator at
an ALOM console to restart the system while you are working inside it. The Standby
position is the only system control keyswitch position that prevents an ALOM user
from restarting the system.
7. Remove the system key from the system control keyswitch, close and lock the
system doors, and keep the key in a secure place.
If desired, you can close and lock the system doors while the mini-key remains in
the system control keyswitch.
