Page 14

1.1 Replaceable Components

Replaceable components in the front of the server are:

■ Bezel assembly

■ Hard drive

■ System configuration card reader

■ Lower interface board

The remaining replaceable components are in the back of the server.

Caution – Printed circuit boards and hard drives contain electronic components

that are extremely sensitive to static electricity. Ordinary amounts of static from your clothes or the work environment can destroy components. Do not touch the components or any metal parts without taking proper antistatic precautions.

Before you carry out the procedures covered in this document, the server must be powered down. To do this you must remove the power cable. Follow the instructions in Section 1.2.2, “Powering Off the Server” on page 1-3.

1.2 Controlling Server Power

The On/Standby button does not power off the server, but it toggles the server between On and Standby mode.

1.2.1 Powering On the Server

Caution – Never move the system when the system power is on. Movement can

cause catastrophic drive failure. Always power off the system before moving it.

1. Connect the server to an AC power source.

Once connected, the server automatically goes into Standby power mode.

2. Turn on power to any peripherals and external storage devices you have connected to the server.

Read the documentation supplied with the device for specific instructions.

1-2 Sun Fire V125 Server Service Manual • September 2006

Page 15

3. Open the bezel.

4. Press the On/Standby switch.

5. Close the bezel.

1.2.2 Powering Off the Server

1. Notify users that the system will be powered down.

2. Back up system files and data.

3. Press and release the On/Standby switch behind the bezel.

The system begins an orderly software system shutdown.

Note – Pressing and releasing the On/Standby switch initiates an orderly software

shutdown. Pressing and holding the switch for four seconds causes an immediate hardware shutdown. Whenever possible, initiate an orderly shutdown. Forcing an immediate hardware shutdown can corrupt the hard drive and cause loss of data.

4. Wait for the front panel green indicator to go out.

Caution – As long as the power cord is connected, potentially hazardous energy is

present inside the server.

5. Disconnect the power cable.

This is the only way to remove power from the server. Electrical power is present when the server is in Standby mode.

1.3 Avoiding Electrostatic Discharge

Whenever you work with the server’s internal components, follow this procedure to prevent damage caused by static electricity.

You need the following items:

■ Antistatic wrist or foot strap

■ Antistatic mat

Chapter 1 Parts Removal and Installation 1-3

Page 16

1.3.1 Avoiding Electrostatic Discharge While Working on the Back of the Server

1. Power off the server.

See Section 1.2, “Controlling Server Power” on page 1-2.

2. Open the back section of the cover.

See Section 1.4, “Opening the Server” on page 1-5.

3. Attach one end of the antistatic strap to the grounding stud located on the partition inside the server, and the other end to your wrist.

FIGURE 1-1 Grounding Point in Back of the Server

1-4 Sun Fire V125 Server Service Manual • September 2006

Page 17

1.3.2 Avoiding Electrostatic Discharge While Working on the Front of the Server

1. Power off the server.

See Section 1.2, “Controlling Server Power” on page 1-2.

2. Perform either Step a or Steps b and c.

a. Attach one end of the antistatic strap to a grounding point on the rack and the

other to your wrist.

b. Remove the server from the rack.

c. Place the server on an antistatic mat or other suitable antistatic surface.

Suitable antistatic surfaces include:

■ Sun electrostatic discharge (ESD) mat, Sun part number 250-1088 (available

through your Sun sales representatives)

■ The bag or shipping container used to package Sun replacement parts

■ Disposable ESD mat, shipped with replacement parts or options

1.4 Opening the Server

The cover of the server is split into two sections, front and back.

■ The back section hinges to provide access.

■ The front section detaches to provide access.

■ The whole cover assembly detaches to provide access to both front and back

sections of the server. This is necessary to replace some components.

Caution – Disconnect the power cord before carrying out this procedure. As long as

the power cord is connected, potentially hazardous energy is present inside the server.

Caution – After servicing, install and fasten the cover before plugging in the power

cords or turning power on.

1.10 Memory

There are four memory module sockets per processor on the system board. Memory is supplied by Sun in pairs. Use the DIMM pair as supplied and do not mix DIMMs.

For a list of the available memory options, see the Sun Fire V125 Server Administration Guide.

1.10.1 Memory Configuration Rules

Memory is shipped in matched pairs for use on the Sun Fire V125 server.

When you install memory into a Sun Fire V125 server, follow the se guidelines:

■ A minimum of two matched DIMMs are required for the server. The matched

DIMMs must be the same size, manufacturer, and part number.

■ DIMMs must be installed in identical pairs. Both size and manufacturer must be

the same per pair, but you can mix manufacturers and size between pairs.

Note – A DIMM pair that has identical attributes, but different vendors will not be

rejecte. However, such a DIMM pair will cause OpenBoot warning message to the console and will disable autoboot.

1.10.2 Installing Memory

1. Power down the server and disconnect the power cable.

See Section 1.2, “Controlling Server Power” on page 1-2

2. Open the back cover.

See Section 1.4.3, “Opening the Back Section of the Cover Assembly” on page 1-7.

3. Install the PCI slider assembly.

The arrow embossed on the slider should point to the rear of the server.

4. Install any PCI cards you removed.

5. Reconnect all system board cables and wiring harnesses.

6. Install the server’s cover and tighten the screws.

1.13 Lower Interface Board Assembly

The interface board assemblies handle the connections between the system board and the components in the front section of the server. The assemblies are positioned in the front section of the server, behind the hard drives and system configuration card reader assembly.

1.13.1 Removing a Lower Interface Board Assembly

1. Power off the server.

See Section 1.2, “Controlling Server Power” on page 1-2.

2. Ensure that the server is properly grounded.

See Section 1.3, “Avoiding Electrostatic Discharge” on page 1-3.

3. Remove all hard drives.

4. Remove DVD drive, if one is fitted in the system.

5. Remove the cover assembly.

See Section 1.4, “Opening the Server” on page 1-5.

6. Disconnect the system board cable.

7. Disconnect the PSU cable.

8. Disconnect the system configuration card reader cable.

9. Unscrew the eight screws that secure the LIB to the server’s chassis as shown in the following figure.

10. Lift the LIB assembly part of the way out of the server chassis.

11. Disconnect the cable from the bezel assembly.

12. Remove the LIB from the server.

1.13.2 Installing a Lower Interface Board Assembly

1. Locate the new LIB assembly using the screw holes at each corner as guides.

The LIB printed circuit board (PCB) pushes onto (blind-mates) its connectors.

2. Screw the LIB into place.

3. Attach the bezel PCB, PSU, and system board cables.

4. Install the cover assembly.
