Lifting the Server
Close the door before you lift the server. The server should be lifted by two people,
using the top part of the bezel at the front and the PSU handles at the back as
gripping points.
Replaceable Components
This section lists components that can be replaced by users and service providers.
■ Components listed in TABLE 1-1 can be replaced by the user.
■ Components listed in TABLE 1-2 can be replaced by the service provider only.

Caution – Printed circuit boards and hard disk drives contain electronic
components that are extremely sensitive to static electricity. The quantities of static
electricity generated by your clothes or your work environment can destroy some
components. Do not touch any components or metal parts without taking full
antistatic precautions.
Caution – Before you carry out any of the procedures covered in this book, the
server must be powered down.
Controlling Server Power
The only way to turn server power off is to disconnect the server from its power
source by removing the power cable or cables. The On/Standby button toggles the
server between the On and Standby power states only; it cannot turn server power
off.
For detailed information on controlling server’s power state using the software, refer
to the ALOM Online Documentation.
Chapter 1 Parts Installation and Removal 3
▼ To Turn Server Power On
Caution – Never move the server while it is powered on. Movement can cause disk
drive failure. Always power off the system before moving it.
1. Connect the server to an AC power source.
When the server is connected to a power source, it immediately enters Standby
power mode.
2. Turn on the power to any peripherals or external storage devices that are
connected to the server.
If you have connected an external device to the server, read the documentation that
was supplied with it for specific instructions.
3. Open the door.
4. Set the operation mode switch to the Normal or Diagnostics position.
5. Press the On/Standby button once.
6. Set the operation mode switch to the Locked position.
This prevents the server from being powered off accidentally.
7. Close and lock the door.
▼ To Turn Server Power Off
1. Notify users that the system will be powered down.
2. Back up system files and data.
3. Set the operation mode switch to the Normal or Diagnostics position.
4. Press and immediately release the On/Standby button.
This action initiates 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 disk drive and cause loss of data.
5. Wait for the front panel green LED to go out.
4 Sun Fire V250 Server Parts Replacement Manual • September 2003
6. 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.
Caution – As long as the power cord is connected, electrical energy is present
inside the server.
Avoiding Electrostatic Discharge
Whenever you carry out service procedures on the server, follow these instructions
to prevent static electricity damaging the server’s internal components.
You need an antistatic wrist strap, an antistatic mat, or other suitable antistatic
surface.
When the AC power cord(s) are removed for a service action to be carried out,
provide a ground path to bring the following to the same electrical potential:
■ ESD protective components
■ Server
■ Antistatic mat
■ Service personnel
Electrostatic protection can be maintained at a potential above a zero voltage ground
reference as long as all items listed above are at the same potential.
▼ To Avoid Electrostatic Discharge While Working
on the Front of the Server
1. Turn system power off.
See “Controlling Server Power” on page 3.
Chapter 1 Parts Installation and Removal 5
2. Attach one end of the antistatic strap to the grounding point on the server’s front
panel behind the door, and the other to your wrist.
See
FIGURE 1-1.
FIGURE 1-1 Front Panel Electrostatic Grounding Point
▼ To Avoid Electrostatic Discharge While Working
On Internal Components
1. Turn server power off.
See “Controlling Server Power” on page 3.
6 Sun Fire V250 Server Parts Replacement Manual • September 2003
2. Attach one end of the antistatic strap to the grounding stud located on the server’s
back panel, and the other end to your wrist.
FIGURE 1-2 Back Panel Electrostatic Grounding Point
Service Panel
Remove the service panel, which is located on one side of the server, to gain access
to the internal components. The service panel is secured to the chassis by two screws
on the back edge of the server.
Caution – The procedures in this section are for the attention of service providers
only.
Chapter 1 Parts Installation and Removal 7
▼ To Remove the Service Panel
1. Turn server power off.
See “Controlling Server Power” on page 3.
2. Ensure you are properly grounded.
See “Avoiding Electrostatic Discharge” on page 5.
3. Unscrew the service panel retaining screws.
The service panel is retained by two captive screws on the right edge of the server’s
back panel. See
FIGURE 1-3.
FIGURE 1-3 Location of the Service Panel Retaining Screws
4. Place the server on its side.
Take care not to damage the feet.
5. Remove the service panel from the body of the server.

2. Unlock and open the door.
3. Slide the catch on the front of the hard disk to the right.
This releases the handle on the front of the hard disk drive. The lever must be open
before you insert the hard disk drive into the server. If it is not, the hard disk drive
will not engage with the server correctly.
12 Sun Fire V250 Server Parts Replacement Manual • September 2003
4. Make sure you are replacing the hard disk drive into the correct bay.
Refer to the note you took when you removed the hard disk drive.
5. Align the hard disk drive with the visual guides printed on both sides of each
hard disk drive bay.
6. Slide the hard disk drive into the server body until the metal lever starts to close.
This indicates that the hard disk drive has engaged with its connector in the server.
7. Press the handle so that the disk drive clicks into place.
FIGURE 1-7 Inserting a Hard Disk Drive
8. Close the door and lock it.
Power Supply Unit
Note – For information on replacing a redundant power supply unit, see the Sun
Fire V250 Server Administration Guide.
Chapter 1 Parts Installation and Removal 13
▼ To Replace a PSU
1. Turn server power off.
See “Controlling Server Power” on page 3.
2. Disconnect the power cable from the PSU.
You cannot remove a PSU unless the power cable has been disconnected.
3. Pull the PSU handle into its down position.
Inside the server, this action breaks the connection between the PSU and the power
distribution board.
FIGURE 1-8 Removing A Power Supply Unit
4. Slide the PSU out of the server body by pulling on the green PSU handle.
FIGURE 1-8.
See
5. Place the module on an antistatic bag or mat.
6. Locate the replacement PSU in the correct bay.
14 Sun Fire V250 Server Parts Replacement Manual • September 2003
7. With the handle in its down position, slide the PSU into the server’s chassis as far
as it will go.
Ensure that the handle does not return to a vertical position until the PSU is as far
into the chassis as it will go, otherwise the PSU will not engage with the power
distribution board inside the server.
FIGURE 1-9 Replacing A Power Supply Unit
8. Press the handle until it clicks home. See FIGURE 1-9.
This action engages the PSU with the power distribution board.
