Installing or Replacing Server Components 59
Installing a PCI Card
You can add to the capabilities of your server by installing cards in its expansion slots. The
computer has three expansion slots, which accommodate Peripheral Component Interconnect
(PCI) cards. In some models, the slot that takes a short (7-inch) PCI card can accept a 4x
Accelerated Graphics Port (AGP) card.
About PCI Cards for the Server
Two of the server’s slots accept PCI cards up to 12 inches long; the third slot accepts a 7-inch
card. (Some models come with a card installed in one or two slots.) Install only expansion
cards that are compatible with Mac OS X and that comply with the PCI 2.1 standard.
PCI Card Requirements
Criteria for PCI cards you can install in the Xserve server are summarized in the table below.
Power Consumption of Cards
Maximum power consumption for all three expansion slots combined should not exceed 50
watts ( W ). Check the documentation that came with each card to be certain that the cards
don’t exceed this power consumption.
