Removing and Replacing Components

This chapter tells you how to remove and replace the components that are located behind the server's front bezel. The procedures documented in this chapter do not require the attention of qualified service personnel.

Caution - Read Avoiding Electrostatic Dischargeand wear a properly grounded antistatic strap, before you carry out any of the procedures in this section.

The chapter contains the following sections:

Replaceable Components

Avoiding Electrostatic Discharge

Swapping a System Configuration Card Between Servers

Removing and Replacing the Hard Drive

Removing and Replacing the DVD Drive

Replaceable Components

Open the bezel to access these components:

System configuration card

Hard drive

DVD drive (shipped or installed as an option)

Note - Access to any other component requires the removal of the server's lid, and involves procedures that must be carried out by trained personnel only.

Avoiding Electrostatic Discharge

You must attach an antistatic wrist strap to the server before you work on the server.

To Avoid Electrostatic Discharge While Working on the Front Panel

1. Attach one end of the antistatic wrist strap to your wrist.

2. Attach the other end to a grounding stud on the rack or cabinet.

Opening the Front Bezel

To install or replace components on the front bezel, you must open it first. This section contains the procedure for opening the front bezel.

To Open the Front Bezel

1. Ensure that you are properly grounded.

See To Avoid Electrostatic Discharge While Working on the Front Panel.

2. Open the bezel by pressing on the release buttons and rotating it down on its hinges.

FIGURE 2-1 Opening the Bezel

Note - Always grip the bezel at both ends to open it. Do not attempt to open it using a single point of grip.

Controlling Server Power

Before you remove or replace a system configuration card or DVD drive, the server must be powered down.

Tip - For detailed information on controlling server power with software, see:
http://docs.sun.com, and search for ALOM documentation.

To Power On the Server

Caution - Never move the system when the system power is on. Movement can cause catastrophic hard drive failure. Always power off the system before moving it.

1. Connect the server to an AC power source.

After the server is 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.

3. Open the front bezel.

4. Press the On/Standby button.

Verify that the indicator for the On/Standby button illuminates.

5. Close the front bezel.

To Power Off the Server

Note - Applications running on the Solaris OS can be adversely affected by a poorly executed system shutdown. Ensure that you have gracefully shut down any applications before powering off the system.

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

2. Back up the system files and data, if necessary.

3. Press and release the On/Standby button behind the front bezel.

The system begins an orderly software system shutdown.

Note - Pressing and releasing the On/Standby button 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.

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

5. Close the front bezel.

Swapping a System Configuration Card Between Servers

Caution - Never remove the system configuration card (SCC) while the server is booting or running the Solaris OS. Either remove power from the server, or put it into Standby mode, before removing or inserting the system configuration card.

Caution - Do not handle the system configuration card unless you need to transfer it to another system. If you need to handle it for this reason, avoid contact with the gold terminals on the underside of the card.

Caution - If you remove the system configuration card and replace it with the SCC from a system of a different platform type, the card will be reconfigured. A message tells you when this has been done, but the system does not request confirmation before reformatting the card.

To Swap the System Configuration Card

1. Power down both servers.

See Controlling Server Power.

2. Open the front bezel on both servers.

See Opening the Front Bezel.

3. Remove the cable ties that secure the system configuration cards, and remove the cards.

4. Insert the system configuration card from the old server into the new one.

5. Replace the cable tie on the new system.

6. Power on the new system.

Removing and Replacing the Hard Drive

If more than one drive is fitted, you can install or remove a hard drive without powering off the server or removing it from the rack. However, you do need to ensure that no system or application software is using a hard drive when you remove it.

Note - If you intend to remove a hard drive with the Solaris OS running, follow the instructions in To Remove a SCSI Hard Drive With the Solaris OS Running before performing the following steps.

Caution - The server and hard drives contain electronic parts that are extremely sensitive to static electricity. Wear a grounded antistatic wrist strap when you carry out this procedure.

To Remove a Hard Drive

1. Open the front bezel.

See Opening the Front Bezel.

2. Check that the blue indicator is lit on the hard drive.

The blue indicator comes on when the hard drive is ready to remove.

3. Slide the catch at the front of the hard drive to the right.

This releases the handle on the front of the hard drive. FIGURE 2-3 shows the server with the optional second hard drive.

FIGURE 2-3 Removing a Hard Drive

Figure shows open bezel and removal of a hard drive.

4. Pull the handle and remove the hard drive from the server by sliding it out from its bay.

To Replace a Hard Drive

Caution - The server and hard drives contain electronic parts that are extremely sensitive to static electricity. Wear a grounded antistatic wrist strap when you carry out this procedure.

1. Open the front bezel.

See Opening the Front Bezel.

2. Slide the catch on the front of the hard drive to the right.

This releases a handle on the front of the hard drive. The lever must be open before you insert the hard drive. If the lever is not open, the hard drive does not engage with the server correctly.

3. Slide the hard drive into its bay at the front of the server.

Push it in firmly until the metal lever starts to close. The hard drive is engaged with its connector attached to the server.

4. Push the metal lever until the drive clicks into place.

5. Close the bezel.

If you have installed a hard drive with the Solaris OS running, perform the steps in To Install a SCSI Hard Drive With Solaris Running.
