Sun Ultra 45 and Ultra 25 Workstations Service and Diagnostics Manual

This chapter describes the removal and installation procedures for Sun Ultra 45 or Ultra 25 workstation storage devices.

The procedures described in this chapter are written for workstation service providers and system administrators.

This chapter contains the following topics:

• Section 4.1, Replacing a Hard Drive
• Section 4.2, Replacing the Hard Drive Backplane and Cables
• Section 4.3, Replacing the I/O Module With the DVD-Dual Drive and Audio USB Board

Caution - To prevent equipment damage, review the safety information in Preparing to Replace Componentsbefore you perform any replacement procedure. Additional cautions, warnings, and instructions are provided in the Sun Ultra 45 and Ultra 25 Workstations Safety and Compliance Guide, 819-2785. The document is available from: http://www.sun.com/documentation.

Caution - When servicing or removing workstation components, attach an antistatic strap to your wrist and then to a metal area on the chassis. Then disconnect the power cord from the workstation and the wall receptacle. Following this caution equalizes all electrical potentials with the workstation.

4.1 Replacing a Hard Drive

The workstation supports up to four hard drives, either serial ATA (SATA), or serial attached SCSI (SAS). The hard drives slide into the hard drive bay and use standard Sun hard drive mounting brackets.

The hard drives are labeled HDD0 through HDD3. The default boot drive is HDD0 (FIGURE 4-1).

TABLE 4-1 lists the hard drive specifications.

4.1.1 Removing a Hard Drive

1. Power off the system and attach an antistatic wrist strap. Open and position the chassis, and remove the access panel.

Refer To Powering Off the Workstation.

2. Press the hard drive release button to release the hard drive handle (FIGURE 4-1).

3. Grasp the hard drive handle and pull the hard drive out of the hard drive bay.

4. Set the hard drive aside on an antistatic mat.

FIGURE 4-1 Removing the Hard Drive

4.1.2 Installing a Hard Drive

Caution - Use proper ESD grounding technique when handling components. Wear an antistatic wrist strap and use an antistatic mat. Store ESD-sensitive components in antistatic bags before placing them on any surface.

1. Power off the system and attach an antistatic wrist strap. Open and position the chassis, and remove the access panel.

Refer to Powering Off the Workstation.

2. Remove the new hard drive from its packaging.

3. Install the hard drive (FIGURE 4-1).

4. Slide the hard drive into the hard drive bay.

5. Close the latch on the hard drive until it clicks and is secure.

6. If you are finished working, reassemble the workstation, power on the workstation, and verify the hard drive installation.

See Finishing Component Replacement.

4.2 Replacing the Hard Drive Backplane and Cables

This section describes removal and installation of the hard drive backplane, the signal cable, and the power cable.

4.2.1 Removing the Hard Drive Backplane and Cables

1. Power off the system and attach an antistatic wrist strap. Open and position the chassis, and remove the access panel.

Refer to Powering Off the Workstation.

FIGURE 4-2 Disconnecting the Cables From the Hard Drive Backplane

2. Remove all hard drives.

See Replacing a Hard Drive.

3. Remove long PCI cards if they are covering the hard drive backplane cables.

Refer to Removing a PCI Card. Set these components onto an antistatic mat.

4. Disconnect the cables from the following connectors

• Hard drive backplane signal cable from J4 of the hard drive backplane and J42 on the motherboard (FIGURE 4-2)
• Power cable P3 from backplane connector J2

5. Using a No. 2 Phillips screwdriver, remove the two screws from the hard drive backplane.

4.2.2 Installing the Hard Drive Backplane and Cables

1. Remove the new hard drive backplane and cables from the packaging.

2. Using a No. 2 Phillips screwdriver, replace the two screws for the hard drive backplane.

3. Reconnect the cables to the following connectors:

• Power cable P3 on backplane connector J2 (FIGURE 4-2).
• Hard drive backplane signal cable from J4 of the hard drive backplane and J42 on the motherboard

4. Inspect the cabling to verify that the signal and power cables are both secure at the backplane and the motherboard.

5. If you removed any long PCI cards, replace them.

Refer to Installing a PCI Card.

6. Reassemble the workstation. Power on the system, and verify the cable installation.

Refer to:

• Reassembling the Workstation
• Verifying Component Installation

4.3 Replacing the I/O Module With the DVD-Dual Drive and Audio USB Board

This section describes removal and installation of the I/O module. The I/O module contains the DVD-dual drive, the audio USB board with speaker, USB and audio connectors, and the Power button and LED.

4.3.1 Removing the I/O Module and DVD-Dual Drive

1. Power off the system and attach an antistatic wrist strap. Open and position the chassis, and remove the access panel.

Refer to Powering Off the Workstation.

2. Open the I/O cable clip at the top of the chassis (FIGURE 4-3).

3. Disconnect the following cables:

• Audio and power cable at J3 on the motherboard
• DVD cable at J11 on the motherboard
• USB cable from at J36 on the motherboard.

New cables are provided with the DVD-dual drive and the I/O module.

If you need to remove a long PCI card to access the USB cable, refer to Removing a PCI Card.

4. Press the I/O module release button and pull the I/O module out the front of the chassis.

Place the I/O module on an antistatic mat.

Caution - Do not attempt to remove the bezel from the front of the I/O module.

FIGURE 4-3 Removing the I/O Module With the DVD-Dual Drive and Audio USB Board

5. If you are only replacing the DVD-dual drive:

a. Using a No. 0 Phillips screwdriver, remove the screws holding the DVD-dual drive into the I/O module.

b. Pull the DVD-dual drive straight out the back of the removable media bay (FIGURE 4-3).

6. If you are replacing the audio USB board:

a. Remove the DVD-dual drive and set it aside.

b. Using a No. 2 Phillips screwdriver, remove the four screws that secure the audio USB board to the I/O module.

c. Pull the audio USB board straight out the back of the removable media bay (FIGURE 4-3).

4.3.2 Installing the I/O Module and DVD-Dual Drive

2. If you are replacing the audio USB board:

a. Install the new audio USB board into the removable media bay (FIGURE 4-3).

b. Replace all four screws that secure the audio USB board to the removable media bay.

3. Install the DVD-dual drive into the I/O module with the screws (FIGURE 4-3):

a. If you are using the old DVD-dual drive, screw the old drive into the I/O module.

b. If you are using a new DVD-dual drive, screw the new drive into the I/O module.

4. Push the I/O module and DVD-dual drive into the chassis until the module clicks (FIGURE 4-3).

5. Connect the cables to the DVD-dual drive and the audio USB board.

If you removed a long PCI card, replace it now. Refer to Section 3.5.5, Installing a PCI Card.

6. Guide the DVD and audio/power cables through the I/O cable clip at the top of the chassis and close the clip.

• Audio and power cable at J3 on the motherboard and J0201 on the audio USB board (FIGURE 4-3 and FIGURE 4-4)
• DVD cable at J11 on the motherboard and J501 on the DVD-dual drive
• USB cable at J36 on the motherboard and J0601 on the audio USB board

FIGURE 4-4 Securing the Audio USB Cables in the I/O Cable Clip

8. Inspect the audio USB board cabling to verify that:
