34 Board Set Description

35MAXDATA PLATINUM 90004R Server System

I/O Board

The I/O board is installed horizontally in the I/O bay. The I/O riser card plugs into a connector on the

I/O board. The I/O provides the following features:

• Intel

E8870 chip set with Scalability Port system interface

• Six functionally independent Peripheral Component Interconnect (PCI) bus segments

• Three hot-plug 133-MHz, 64-bit PCI-X slots

• Five hot-plug 100-MHz, 64-bit PCI-X slots

• Integrated dual channel LSI 53C1030 Ultra320 Low Voltage Differential SCSI (LVDS) controller

• I/O riser support connector for I/O interface

• On-board power conversion from 48 V bulk power

• System reset and clock generation circuits

• I2C server management interface

• Redundant hot-plug system fan interface

I/O Riser

To conserve space on the I/O board, most system I/O and server management functions have been

placed on the I/O riser card that plugs into the I/O board. The I/O connectors include video, serial,

Local Area Network (LAN), and Universal Serial Bus (USB). The I/O riser:

• Contains an IDE bus controller and connector. The IDE bus is routed to the I/O board where it is

further routed to the midplane board’s disk bay connector.

• Converts 12 V STDBY (standby) to +5 V STDBY and +3.3 V STDBY and supplies them to the I/O

board.

• Mates directly onto the I/O board and together they contain all of the I/O interfaces for the

board set.

The I/O riser provides the following features:

• One I/O Control Hub 4 (ICH4) component

– Four Universal Serial Bus (USB) ports

– One IDE interface routed through the I/O board connector

• Network Interface Card (NIC) Intel

82540EM 10/100/1000 Ethernet controller

– Ethernet port with I

C support

• Low Pin Count (LPC) Super I/O

– One serial port

• 3 MB of ash memory

• Server management controller

• Integrated Intelligent Chassis Management Bus (ICMB)

• Integrated Rage XL video controller and memory

– Video port

– Power control - Advanced Configuration and Power Interface (ACPI)

• Speaker control

• Integrated standby voltage DC-to-DC converters generating 3.3 V standby and 5 V standby
