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. 12-inch PCI card 64-bit or 32-bit data width 66 or 33 MHz frequency (If a 33 MHz card is used in one slot, both cards operate at 33 MHz.) 3.3 volt ( V ) 12 or 7 inches long 7-inch PCI card 32-bit data width 66 MHz frequency 3.3 V 7 inches long 4x AGP card with an AGP adapter Important The PCI card must have a 3.3 V connector or a universal connector to fit into the server's expansion slots. Cards with a 5 V connector will not work in this server. 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. Installing or Replacing Server Components 59
