1.2 Sun Fire X4440 Server Chassis Overview

The Sun Fire X4440 Server is based on an all-new chassis family.

Note - Some of the procedures in this manual are for customer-replaceable units (CRUs) and some are for field-replaceable units (FRUs), as noted in the procedures and in the list below. FRU components should be replaced only by trained service technicians. Contact your Sun Service representative for assistance with FRU replacements.

1.2.1 Infrastructure Boards

The Sun Fire X4440 has the boards listed in TABLE 1-2 installed in the chassis.

TABLE 1-2 Infrastructure Boards






The motherboard is on a removable tray. It has 16 DIMM slots and the service processor (ILOM) subsystem. Hyper-transport connector slots to a mezzanine tray support two additional processors and memory.

The server motherboard provides an integrated lights out management (ILOM) service processor function, which includes remote boot and remote software upgrades. The service processor (ILOM) subsystem controls the host power and monitors host system events (power and environmental). The iILOM controller draws power from the host’s 3.3V standby supply rail, which is available whenever the system is receiving AC input power, even when the system is turned off.

Servicing the Motherboard Assembly


Refer to the Sun Fire 4140, 4240, and 4440 Server Diagnostics Guide for ILOM sensor information.

Refer to the Sun Integrated Lights Out Manager 2.0 User's Guide

Mezzanine tray


This removable mezzanine tray includes 2 additional CPU modules, slots for 16 DIMMs, and memory control subsystems.

Servicing the Mezzanine Tray

Power distribution board


This power distribution board board distributes main 12V power from the power supplies to the rest of the system. It is directly connected to the Vertical PDB card, and to the motherboard through a bus bar and ribbon cable. It also supports a top cover interlock (“kill”) switch.

In the Sun Fire X4440, the power supplies connect to the power supply backplane which connects to the power distribution board.

Servicing the Power Distribution Board (PDB)

Vertical PDB card


This vertical power distribution board serves as the interconnect between the power distribution board and the fan power boards, drives backplane, and I/O board.

Servicing the Paddle Card

Power supply backplane card


This board connects the power distribution board to power supplies 0 and 1.

Servicing the Power Supply Backplane

Fan power boards (2)


These boards carry power to the system fan modules. In addition, they contain fan module status LEDs and transfer I2C data for the fan modules.

Servicing the Fan Power Boards

Drives backplane


This board includes the connectors for the drives, as well as the interconnect for the I/O board, Power and Locator buttons, and system/component status LEDs. The Sun Fire X4440 has an eight-disk backplane. Each drive has an LED indicator for power/activity, fault, and ok-to-remove.

Servicing the Drives Backplane

Front I/O board


This board carries the front panel USB connections from the drives backplane. The board connects directly to the drives backplane. It is packaged with the DVD drive as a single unit.

Servicing the DVD/USB Module

PCIe risers


In the Sun Fire X4440, each riser supports two PCIe cards. There are three risers per system, each attached to the rear of the motherboard.
