Preparing For Installation - Sophisticated Circuits PowerKey Pro 200 User Manual

Preparing for Installation

Determine your computer's switch type
With your computer off, press the "Power On" key
(usually found at the top or upper right corner of
your keyboard). If your computer starts up it has Soft
Power, otherwise it has Hard Power. This informa-
tion will be important later when you are connecting your
computer's power cords to your PowerKey Pro.
If your computer started up in the above test (i.e. it has Soft
Power), shut it down before continuing.
Unplug your system
1. Make sure that all the power switches on your Macintosh
and peripherals are turned off.
2. Disconnect the power cords for your Macintosh and
peripherals from the wall outlet or power strip.
3. Disconnect the keyboard cable from the Apple
Desktop Bus ("ADB") port on the back of your
computer. The ADB port is labelled with the icon
shown at the right.
4. If you have a modem, unplug the phone cable leading
from the wall to the modem.
