HP Compaq dc7800 User Manual

Drives
The computer supports up to five drives that may be installed in various configurations.
When installing additional drives, follow these guidelines:
●
The primary Serial ATA (SATA) hard drive must be connected to the dark blue SATA connector
on the system board labeled SATA0.
●
Connect the first SATA optical drive to the white SATA connector on the system board labeled
SATA1.
●
Always populate the dark blue SATA0 and white SATA1 connectors before the light blue SATA4
and orange SATA5 connectors.
●
Connect a second SATA optical drive to the orange SATA5 connector.
●
Connect additional SATA hard drives to the next available (unpopulated) SATA connector on the
system board in the following order: SATA0, SATA1, SATA5, SATA4.
●
Connect a diskette drive to the connector labeled FLOPPY.
●
Connect a media card reader to the USB connector labeled MEDIA CARD.
●
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.
●
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 installed on the chassis. The hard drive uses 6-32
isolation mounting guide 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 guide screws are black. The HP-
supplied 6-32 isolation mounting guide screws are silver and blue.
6-32 isolation mounting screws for the hard drive (shown below).
M3 metric screws for all drives other than hard drives (shown below).
