Installing Additional Drives

When installing additional drives, follow these guidelines:

●The primary Serial ATA (SATA) hard drive must be connected to the dark blue primary SATA connector on the system board labeled SATA1.

●Connect the first SATA optical drive to the white SATA connector on the system board labeled SATA2.

●Always populate the dark blue SATA1 and white SATA2 connectors before the light blue SATA3 and orange SATA4 connectors.

●Connect a second SATA optical drive to the orange SATA4 connector.

●Connect additional SATA hard drives to the next available (unpopulated) SATA connector on the system board in the following order: SATA1, SATA2, SATA4, SATA3.

●Connect a diskette drive to the connector labeled FDD1.

●Connect a media card reader to the USB connector labeled JUSB2.

●The system does not support Parallel ATA (PATA) optical drives or PATA hard drives.

●You may install either a third-height or a half-height drive into a half-height bay.

●If needed, HP has provided extra drive retainer screws on the interior of the front bezel that are used to secure the drives in the drive cage. Hard drives use 6-32 standard screws. All other drives use M3 metric screws. The HP-supplied M3 metric guide screws (1) are black. The HP-supplied 6-32 standard screws (2) are silver.
