5.25-inch Drive Bays
Two empty 5.25-inch drive bays allow installation of additional externally-
accessible devices.
Power Switch
The power switch allows you to turn the system power on or off.
Reset Switch
Pressing the reset switch generates a hardware reset pulse that restarts the system
initializing all the registers, buffers, and memory subsystems.
Keylock
The keylock gives security to the system against unauthorized users. Turning the
keylock to the unlocked position enables the power and reset switches. Turning
the keylock to the locked position disables both switches whether the system is on
or off. Supposing the system is on and you intend to reset or turn it off, make
sure that the keylock is unlocked. Otherwise, the switches do not respond.
