Description
The processor board supports up to four Intel Itanium
processors and 48V power pods.
Installed: Up to four Intel Itanium processors, packaged
in Slot M pin array cartridges.
Two plug-in boards containing main memory supporting
PC100 Version 1.2 buffered SDRAM. Each memory board
supports from 1 GB to 32 GB of error correction code
memory using 32 72-bit dual inline memory modules. The
boards interface to the processors via connectors on each
side of the processor board.
Eight 64-bit/66 MHz Hot Plug PCI slots.
Two 64-bit/33 MHz Non-hot Plug PCI slots.
ATI RAGE † XL PCI super video graphics array controller
with 16 MB of video memory.
The QLogic † ISP 12160 LVDS SCSI controller supports two
LVDS channels. One channel is used internally to provide
support for the internal SCSI drives (connected to the LVDS
disk backplane). The second LVDS channel is routed to the
rear of the chassis to support external devices.
This board contains all legacy I/O connections and plugs
into an edge connector on the I/O baseboard.
PS/2-compatible keyboard and mouse ports.
PS/2-compatible parallel port.
The PCI-enhanced Integrated Drive Electronics interface
has two IDE buses, supporting the diskette drive (Primary
IDE 0) and DVD drive (Secondary IDE 1).
Two universal serial bus ports.
Two PS/2-compatible, 9-pin serial ports.
This backplane supports up to two 1-inch SCA2-type LVDS
SCSI drives, mounted in carriers.
The front panel board provides the user interface to the
server.
Push-button switches control power-up, reset, and
initialization functions.
LEDs indicate power on, power supply failure, hard drive
failure, or a fan failure.
An LCD panel provides information about boot status,
available number of processors.
The Sideplane board:
Electrically connects the processor board and I/O
baseboard. Interconnects to the Power Distribution board.
Contains the sockets for the 5 V and 3.3 V DC-to-DC
converters.
Distributes DC power to the power bay, I/O bay, and
docking board.
Distributes the power load of the server among four 800-
watt autoranging power supplies.
