1.2 Sun Fire X4450 Server Chassis Overview

The Sun Fire X4450 server is based on an all-new chassis family.

1.2.1 Infrastructure Boards

The Sun Fire X4450 server has the following boards installed in the chassis. The boards are listed in TABLE 1-2.

TABLE 1-2 Infrastructure Boards





The motherboard includes CPU modules, a removable tray with slots for 32 DIMMs, memory control subsystems, and the service processor (lights out management (LOM)) subsystem.

The service processor (LOM) subsystem controls the host power and monitors host system events (power and environmental). The LOM 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.

Section 4.8, Servicing the Motherboard Assembly

Power distribution board

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

In the Sun Fire X4450, the power supplies connect directly to the power distribution board.

Section 5.5, Servicing the Power Distribution Board (PDB)

Paddle card

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

Section 5.7, Servicing the Paddle Card

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.

Section 5.1, 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 X4450 has an eight-disk backplane. Each drive has an LED for power/activity, fault, and ok-to-remove.

Section 5.3, Servicing the Drives Backplane

Front I/O board

This board connects directly to the drives backplane. It is packaged with the DVD drive as a single unit.

Section 3.5, Servicing the DVD/USB Module

PCIe risers

There are three risers per system, each attached to the rear of the motherboard. In the Sun Fire X4450 server, each riser supports two PCIe cards.

Note - System cooling might be affected by dust and contaminant build-up. It is recommended that systems be opened and checked approximately every six months, or more often in dirty operating environments. Check system heat sinks, fans, and air openings. If necessary, clean systems by brushing or blowing contaminants or carefully vacuuming contaminants from the system.
