Apple Workgroup Server 8150/110 - Manual (Page 42)

Installing an expansion card
You can install printed circuit boards (called cards) for video and graphics
applications, networking and communications, additional processing power,
or other purposes. The cards fit into connectors, called expansion slots, inside
the server.
Your server has three expansion slots designed to accept NuBus™ cards and
one slot that will accept a processor-direct slot (PDS) card. All four slots can
be used simultaneously.
Power requirements
The combined power consumption of expansion cards must not exceed the
limits specified for your Workgroup Server 8150. If you have more than one
expansion card installed, check the information that came with your cards to
make sure that their power consumption is within the limits specified in your
server’s Technical Information booklet.
Installing the card
IMPORTANT Some cards may need to be installed by an Apple-authorized
service provider. Check the information that came with the card.
Follow these steps to install an expansion card.
1 Shut down the server, disconnect any attached cables (including the power cord) and
press the power switch to discharge static electricity.
2 Loosen the four large screws at the corners of the back panel.
Do not remove the screws or the back panel.
WARNING The processor-direct slot (PDS) must always be occupied by
either the termination card that came with your server or a functional
card such as a video card. Be sure to keep the termination card if you
replace it—you’ll need to reinstall the termination card should you later
remove the replacement card.
