Apple Workgroup Server 8550 - Manual (Page 43)

Installing an expansion card
You can install printed circuit boards (called cards) for networking and
communications, SCSI acceleration, video and graphics applications, or
other purposes. The cards fit into connectors, called expansion slots, inside
the server.
Your Workgroup Server 8550 has three expansion slots, each designed to
accept a Peripheral Component Interconnect (PCI) card. Install only
expansion cards that come with Mac OS drivers and are compliant with the
PCI 2.0 standard. NuBus cards cannot be used in your server’s expansion
slots. There is also an expansion slot that contains the server’s processor card.
(The processor card can be upgraded by replacing it with a more powerful
processor card.)
Power requirements
The combined power consumption of expansion cards must not exceed the
limits specified for your Workgroup Server 8550. 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
Appendix B, “Technical Information.”
WARNING To avoid damaging your server and expansion card, do not
attempt to install any expansion card without first checking the
documentation for that card. If the documentation specifies that an
Apple-certified technician must install the card (usually because the
installation requires special training or tools), consult the service and
support information that came with your server for instructions on
how to contact an Apple-authorized service provider or Apple for
assistance. If you attempt to install the card yourself, any damage you
may cause to the server or card will not be covered by the limited
warranty on your server. If the card is not an Apple-labeled product,
check with an Apple-authorized dealer or service provider to see if you
can install it yourself.
