1.2 Server Chassis Overview

The following sections provide an overview of the server chassis.

1.2.1 Infrastructure Boards

The server boards are listed in TABLE 1-2.

TABLE 1-2 Infrastructure Boards





The motherboard includes sockets for 2 CPU modules; slots for 18 DDR3 DIMMs; 1 port for a USB flash drive; and the ILOM service processor.

The ILOM service processor (SP) controls the host power and monitors host system events (power and environmental). The ILOM SP draws 3.3V standby power from the power supply when AC power is applied (without the host being powered on) even when the system is turned off.

Servicing the Motherboard

Power distribution board

The power supplies connect directly to the 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 board, and to the motherboard via a bus bar and ribbon cable. The power distribution board also has a connector for connecting the top-cover interlock (“kill”) switch.

Servicing the Power Distribution Board

Paddle board

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

Servicing the Paddle Board

Fan board

This board carries power to the system fan modules. In addition, the board transfers sensor data for the fan modules.

Servicing the Fan Board

Disk backplane

This board includes the connectors for the storage drives, as well as the interconnect for the I/O board, Power and Locator buttons, and system/component status LEDs. The Sun Fire X4170 M2 Server has an eight-disk backplane. Each storage drive has LEDs that indicate Power/Activity, Fault, and OK-to-Remove status.

Servicing the Disk backplane

Front I/O board

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

Servicing the DVD/USB Module

PCIe risers

There are three risers per system, each attached to the rear of the motherboard.

  • Each riser supports one PCIe card.
  • All PCIe slots support PCIe Gen 2.

1.5 Server Status Indicators and LEDs

The server provides many status indicators and LEDs to assist you in monitoring and managing the server.

1.5.1 Server General Status Indicators

There are six system-level indicators, some of which are located on both the server front panel and the server back panel. These indicators are described in TABLE 1-5.

TABLE 1-5 Server General Status LEDs

Indicator/LED Name



State Meaning



This LED indicates the operational state of the chassis. This LED can be in the following states:

  • OFF - AC power is not present or the ILOM boot has not completed.
  • STANDY BLINK - Standby power is on, but the chassis power is off and the ILOM SP is running.
  • SLOW BLINK- Startup sequence has been initiated on the host. This pattern should begin soon following powering on the server. This status indicates either 1)POST diagnostics running on server host system, or 2) the host is transitioning from the powered-on state to the standby state on shutdown.
  • STEADY ON - The server is powered on and all host POST tests have completed. The server is in one of the following states: 1) the server host is booting the operating system (OS), 2) the server host is running the OS.

Service Required


  • OFF - Normal operation
  • STEADY ON - Fault present on server. This indicator lights whenever a fault LED lights for a server replaceable component.

Note - The lighting of this indicator is always accompanied by the system console message that includes a recommended service action.



  • OFF - Server is operating normally
  • FAST BLINK - Use ILOM to activate this indicator to enable you to locate a particular system quickly and easily.
  • Pressing the Locate button will toggle LED FAST BLINK on or off.

Top Fan Failure



Indicates that one or more of the internal system fan modules have failed.

  • OFF - Indicates steady state; no service action is required
  • STEADY ON - Indicates service action required; service the fans.

Rear Power Supply Failure



Indicates that one of the server power supplies has failed.

  • OFF - Indicates steady state; no service action is required.
  • STEADY ON - Indicates service action required; service the power supply.



OFF - Normal operation; no service action is required.

STEADY ON - The system is experiencing an overtemperature warning condition.

Note - This is a warning indication, not a fatal overtemperature. Failure to correct this might result in the system over heating and shutting down unexpectedly.

1.5.2 Server Fan LEDs

Each fan module has one bicolored, status LED. The fan LEDs are visible when the top cover fan door is open. See TABLE 1-6.

TABLE 1-6 Server Fan Status LEDs

LED Name



State Meaning

Fan Status


Bicolored: Amber/Green

  • Amber - There is a fan fault.
  • Green - Fan is properly installed and functioning correctly. No fan errors detected.

1.5.3 Storage and Boot Drive LEDs

There are three LEDs on each drive. See TABLE 1-7.

TABLE 1-7 Server Front Storage Disk LEDs

LED Name



State Meaning



  • OFF - Power is off or installed drive is not recognized by the system.
  • STEADY ON - The drive is engaged and is receiving power.
  • STANDBY BLINK - There is disk activity. LED blinks on and off to indicate activity.

Service Required


  • OFF - Normal operation.
  • STEADY ON - The system has detected a fault with the storage drive.

Ready to Remove


The storage drive can be removed safely during a hot-plug operation.

1.5.4 Power Supply LEDs

There are three LEDs on each power supply. These LEDs are visible from the rear of the server. See TABLE 1-8.

TABLE 1-8 Server Power Supply LEDs

LED Name



State Meaning



  • STEADY ON - Normal operation. DC output voltage is within specification.
  • OFF: 12V power is disabled.

Service Required


  • OFF - Normal operation; no service action required.
  • STEADY ON - The power supply (PS) has detected a PS fan failure, PS overtemperature, PS over current, or PS over/under voltage.




  • OFF - No AC power is present.
  • STEADY ON - Normal operation. Input power is above minimum specification.

1.5.5 Motherboard LEDs

The motherboard contains the several LEDs, which are described in the following sections:

Note - A super capacitor provides sufficient power for the motherboard LEDs to be lit for up to 15 minutes after the removal of the server’s top cover. After 15 minutes, the capacitor might be discharged enough so that lighting the fault LEDs is not possible. DDR3 DIMM Fault LEDs

Each of the 18 DDR3 DIMM slots on the motherboard has an amber fault LED associated with it. If ILOM determines that a DIMM is faulty, pressing the Fault Remind button on the motherboard signals the service processor to light the fault LED(s) associated with the faulted DIMM(s). CPU Fault LEDs

The motherboard includes a fault LED adjacent to each of the two CPU sockets. These LEDs indicate when a CPU is faulty. For example, if on reboot the BIOS detects that there are uncorrectable CPU errors recorded in the MCA registers apparently left over from the previous boot, then the BIOS and ILOM work together to record and diagnose these errors. If it is determined that a CPU is faulty, pressing the Fault Remind button on the motherboard signals the service processor to light the fault LED(s) associated with the faulted CPU(s). Fault Remind Super Capacitor Power LED

This LED is located next to the Fault Remind button and is powered from the super capacitor that powers the fault LEDs on the motherboard. This LED lights to indicate to the user that the fault remind circuitry is working properly in cases where no components have failed and, as a result, none of the component fault LEDs illuminate. 3.3V_STANDBY OK LED

The service instructions for all internal components require that all AC power be removed from the power supplies prior to the server’s top cover being removed. This green LED is located on the motherboard and it lights to inform a service technician that the motherboard is receiving standby power from at least one of the power supplies. This indicator is provided to help prevent service actions on the server’s internal components while the AC power cords are installed and power is being supplied to the server.
