Figure 1-4. Back panel
The back panel components work as follows:
Switched AC outlet. Auxiliary power outlet. You can plug the power
cord of an IBM-compatible monochrome monitor into this outlet, if
the monitor’s power consumption does not exceed
1
amp. The main
unit’s power switch controls the monitor connected to this outlet.
Unswitched AC outlet. Auxiliary power outlet. You can plug a
peripheral such as a color monitor or a printer into this outlet, if the
peripheral’s power consumption does not exceed 1.5 amps. The
main unit’s power switch does not control the peripheral connected
to this outlet.
AC input. Plug the power cord into the main unit here to supply
electrical power to the computer. Make sure the computer is off
when you plug the power cord into a wall outlet.
Composite video port. You can plug a composite monitor into this
RCA-type phono jack. See “Setting the DIP Switches” in this chapter
to find out how to set switches
