Apple Workgroup Server 6150/66 - Manual (Page 42)

Installing an expansion card
You can install a printed circuit board (called a card) for video and graphics
applications, networking and communications, additional processing power, or
other purposes. The card fits into a connector, called an expansion slot, inside
the server.
Your server has one expansion slot designed to accept a processor-direct slot
(PDS) card or a NuBus™ card. Each card requires an adapter, which allows it
to fit into the expansion slot.
IMPORTANT The Workgroup Server 6150 does not accept expansion cards that
are more than 7 inches in length.
WARNING Do not remove any factory-installed cards from inside your
server. Pulling a factory-installed card out at an angle can damage your
equipment. Any expansion card you install will not operate properly if a
factory-installed card has been removed. If a factory-installed card needs
to be removed, see an Apple-authorized service provider.
WARNING Be sure to use the adapter designed specifically for the
Workgroup Server 6150. Failure to do so could damage the card and
your server.
