Features

The AA9100 is a dual-processor system board that supports Intel Pentium II CPU's
through an add-in CPU board.
This high-performance 64-bit system board utilizes both the ISA and the PCI local
bus architecture. Two ISA and five PCI bus slots reside on the board to allow
installation of either master or slave devices.
A 50-pin SCSI interface and two 68-pin Ultra Wide SCSI interfaces come with the
system board to connect SCSI devices. External I/O interfaces include a parallel
port and a video port, RJ-45 and USB connectors, and keyboard and mouse ports.
The system board supports two server management features, ASM Pro and
Remote Diagnostic Manager (RDM), that allow better server management. ASM
Pro detects problems in a CPU thermal condition, CPU working voltage detection
(±12V/±5V/3.3V/1.5V), and calculating PCI bus utilization. It also detects if the
CPU fan or chassis fan malfunctions. RDM allows execution of the RDM diagnostic
program from a remote RDM station to fix detected problems or to reboot the
system.
