Your Macintosh has four expansion slots, each of which accepts a PCI card up to 12 inches long. Install only expansion cards that come with Macintosh driver software and that comply with the PCI 2. 1 standard. NuBusTM cards cannot be used in these expansion slots. In standard Macintosh models, a graphics card that supplies a monitor port occupies the PCI slot labeled number 1. This slot can accommodate 3. 3 volt ( V ) cards with 66 MHz frequency and 32-bit data widths only. The other three PCI slots can accommodate mixed voltage (5. 0 V or 3. 3 V ) cards with a 33 MHz frequency and 32-bit or 64-bit data widths. To use a 66 MHz card in one of these three slots, the card must be designed to function at both 66 MHz and 33 MHz; it will work at the lower 33 MHz frequency when installed. Warning Do not use cards that function at only 66 MHz in these three PCI slots. If you have a 66 MHz card, check the card's manufacturer to see if it also works at 33 MHz. 30 Chapter 2 The factory-installed video card that provides your computer's monitor port functions at 66 MHz and 33 MHz. Expansion Card Power Requirements The combined power consumption of expansion cards must not exceed the limits specified for your Macintosh model. For details, see the technical information section in the electronic documentation that came with your computer. You can use the three 33 MHz expansion slots to install m three 15 W cards m one 15 W or 25 W card m two 15 W or 25 W cards m one 15 W card and one 25 W card To avoid damaging your computer and expansion card, do not attempt to install any expansion card without first checking the documentation for that card. With the ejectors in the open position (as shown), push down on the DIMM until it snaps into place. Ejector (Your slot may have one or two ejectors.

If you want to install other items, go to the relevant section. To install Go to the section Internal storage device PCI expansion card New battery "Installing a Hard Disk or Other Internal Storage Device, " below "Installing a PCI Expansion Card" on page 49 "Replacing the Battery" on page 52 Installing a Hard Disk or Other Internal Storage Device The lower drive bay in the drive carrier at the top of your Macintosh can accommodate an internal Zip drive, if one did not come installed in the computer. The lower portion of the computer can accommodate up to three 1. 0-inch and 1. 6-inch SCSI and ATA internal storage devices. Before installing an internal storage device, read "About Internal Storage Options" on page 27 and follow the steps in "Opening the Computer" on page 32. Important If you want to add a SCSI drive to a computer, you must first install an appropriate PCI card. Follow any instructions that came with the card and the instructions in the section "Installing a PCI Expansion Card" on page 49. After the card is installed, return to this section. It's easiest to connect cables to the card if you install the card in the PCI slot labeled 3. 38 Chapter 2 Installing an Internal Storage Device 1 Unplug the power cord bundle from the main logic board and the ribbon cable from the drive. If you're working with SCSI drives, disconnect the power cord bundle from the main logic board. Unplug the power cord bundle from the main logic board. Unlock the power cord bundle plug by pressing the small catch located on the side of the plug. (Side view) Unplug the ribbon cable from the hard disk drive.

[. . . ] Le matériel doit également être installé en suivant une méthode acceptée de raccordement. Dans certains cas, le câblage appartenant à l'entreprise utilisé pour un service individuel à ligne unique peut être prolongé au moyen d'un dispositif homologué de raccordement (cordon prolongateur téléphonique). L'abonné ne doit pas oublier qu'il est possible que la conformité aux conditions énoncées ci-dessus n'empêche pas la dégradation du service dans certaines situations. De fait, les entreprises de télécommunication ne permettent pas que l'on raccorde un matériel aux prises d'abonnés, sauf dans les cas précis prévus par les tarifs particuliers de ces entreprises.
