System Components
PCI Architecture
Your system's PCI architecture represents the latest advances in local bus technology. The
Digital AlphaStation 400 Series system PCI architecture delivers maximum performance
by providing a wider data path, greater speed, and improved expandability. Now, you can
move ISA bus peripheral controller functionality over to the PCI bus with available PCI
peripheral controllers. The result is faster data transfers for devices such as SCSI
controllers and high-end video adapters—a critical advantage when you are running
graphic- and I/O-intensive software.
PCI local bus features include:
•
Highest performance in the market today.
•
Best expandability for high-performance peripheral devices.
•
Support for multiple bus masters.
•
32-bit data transfer at 132 MB (megabytes) per second (peak).
•
PCI-to-ISA bridge capability that allows you to use commonly available ISA options.
SCSI Controller
The Digital AlphaStation 400 Series system uses a PCI-based embedded SCSI-2 controller
that controls up to seven SCSI peripherals such as hard disk drives, CD-ROM (compact
disc read only memory) drives, and tape drives.
Keyboard
Your system comes equipped with a 101-key enhanced keyboard that allows you to
communicate with your system by entering data or commands. Notice that some European
language keyboards have 102 keys. You can adjust the angle of the keyboard for your
comfort. The underside of the keyboard has feet that swing down and lock into place.
Refer to Figure 2-1 and Table 2-1 for information on keyboard key groups and functions.
F
Refer to your operating system or application software documentation for
software-specific key functions.
