Hardware Upgrades Installing Additional Drives The computer supports up to six drives that may be installed in various configurations. When installing additional drives, follow these guidelines: ■ The primary Serial ATA (SATA) hard drive should be connected to the primary SATA controller on the system board labeled P60 SATA 0. Connect a second SATA hard drive to the secondary SATA controller labeled P61 SATA 1. Connect a third SATA drive to P62 SATA 2 and a fourth SATA drive to P63 SATA 3. HP does not support connecting both SATA and 3.5-inch PATA hard drives on the same system. ■ Connect Parallel ATA (PATA) expansion devices, such as optical, IDE tape, and Zip drives, to the PATA controller (labeled P20 PRIMARY IDE) using a standard 80-conductor cable. ■ You may install either a third-height or a half-height drive into a half-height bay. ■ You must install guide screws to ensure the drive will line up correctly in the drive cage and lock in place. HP has provided extra guide screws with the computer. The hard drive uses 6-32 standard screws, four of which are installed on the hard drive bracket under the access panel. All other drives use M3 metric screws, eight of which are installed on the diskette drive bracket under the access panel. The HP-supplied metric screws are black. The HP-supplied standard screws are silver. 2-22 www.hp.com Hardware Reference Guide
