• Low Pin Count (LPC) bus provides access to three Keyboard Controller Style (KCS) and one-Block
Transfer (BT) interface.
• 32-bit ARM7 RISC processor.
• 160-pin Low Profile Flat Pack (LQFP) package.
• Firmware is provided for the following interfaces:
—IPMI
—IPMB
SCSI Controller
The SCSI controller is a LSI Logic 53C1030 chip. This chip is fully compliant with the SCSI Peripheral
Interface-4 Specification (SPI-4). It has two independent SCSI channels supporting devices at speeds up to
320 MB/sec each. The 53C1030 adheres to the PCI-X addendum, to the PCI Local Specification, and is
hard-wired to PCI ID 1 which corresponds to bit 17 of the PCI AD bus.
IDE Interface
The IDE controller (PCI649) supports the ATAPI zero (0) to five (5) modes (from 16 to 100 MB/s). The usable
speed on this system is limited to 16 MHz (ATA-33 mode, 33 MB/s) because the slimline CD/DVD devices do
not support the ATA-66 and 100 modes.
The primary IDE channel is the only channel that is implemented. The IDE cable provides only one drive
connector, of the master type, for the optical storage peripheral.
1 GB System LAN
The 1 GB System LAN port provides:
• Main system LAN.
• 10/100/1000 MB capable.
USB Connectors
The USB connectors provide:
• High speed 480 MB/sec. capable.
• Full speed 12 MB/sec. and low speed 1.5 MB/sec.
• Support for USB keyboard and mouse.
• HP-UX supports HP USB keyboard and mouse.
