Processor overview
Each Intel Itanium processor is packaged in a Slot M pin array cartridge. Depending
on configuration, your system has one to four processors. Each processor is powered
by a 48V power pod, located adjacent to the processor on the processor board.
Attached to the top of each processor is a heat sink that dissipates thermal energy.
Attention: Processors should only be installed, removed, or replaced by a trained
servicer who is familiar with IBM products.
When shipping, unpacking, or handling Intel Itanium processors, be sure to follow
the guidelines described in "Handling electrostatic discharge-sensitive devices" on
page 260.
Memory overview
Memory resides on two memory boards. Each memory board contains slots for 32
DIMMs and is attached to the processor board through a 300-pin connector. The
memory controller supports PC 100-registered Version 1.2 Buffered SDRAM DIMMs.
DIMM sizes supported are 256 MB, 512 MB, and 1 GB. Each memory board can
support from 512 MB to 32 GB. The xSeries 380 server can support up to 64 GB of
system memory.
Description
The SCSI Backplane supports up to two 1-inch SCA2-type
LVDS SCSI drives, mounted in carriers.
The Front Panel 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 prov ides information about boot status and
av ailable number of processors.
•
Electrically connects the Processor Baseboard and I/O
baseboard.
•
Contains the connectors for the 5 V and 3.3 V DC-to-DC
converters.
•
Distributes DC power to the I/O Baseboard.
•
Interconnects to the T-Docking Board.
The T-Docking Board connects to the I/O Baseboard through
the interconnect cable. The T-Docking Board also connects to
the SCSI Backplane. The board distributes the power load of
the server among three to four 800-watt autoranging power
supplies, contains the socket for the 12V DC-to-DC converter
for the LVDS drives, and provides power to the 172 mm and
120 mm fans.
