Replacing Field-Replaceable Units

This chapter describes how to remove and replace customer-replaceable field-replaceable units (FRUs) in the server.

The following topics are covered:

For a list of FRUs, see Appendix A.



Note - Never attempt to run the system with the cover removed. The cover must be in place for proper air flow. The cover interlock switch immediately shuts the system down when the cover is removed.




5.1 Replacing the Optional PCI-Express Card

5.1.1 Removing the Optional PCI-Express Card

Use this procedure to remove the optional low-profile PCI-Express (PCI-E) card from the server.

1. Perform the procedures described in Chapter 4.

2. Remove any cables that are attached to the card.

3. On the rear of the chassis, pull the release lever that secures the PCI-Express card to the chassis (FIGURE 5-1).

5. Place the PCI-Express card on an antistatic mat.

5.1.2 Installing the Optional PCI-Express Card

Use this procedure to replace the PCI-Express cards.

1. Unpack the replacement PCI-Express card and place it on an antistatic mat.



Note - Only low-profile PCI-Express cards with low brackets fit into the chassis. There are a variety of PCI-Express cards on the market. Read the product documentation for your device for additional installation requirements and instructions that are not covered here.



2. Insert the PCI-Express card into the connector on the PCI-Express riser board and the note slot (FIGURE 5-2).

3. On the rear of the chassis, engage the release lever to secure the card to the chassis (FIGURE 5-1).

4. Perform the procedures described in Chapter 6.


5.2 Replacing the Fan Tray Assembly

5.2.1 Removing the Fan Tray Assembly

1. Perform the procedures described in Chapter 4.

2. Disconnect the fan power cable from the motherboard.

3. Push in on the clasps on both sides of the fan assembly (FIGURE 5-3).

4. Remove the fan assembly from the sheet metal mounting brackets.

5.2.2 Installing the Fan Tray Assembly

1. Unpack the replacement fan tray assembly and place it on an antistatic mat.

2. Align the fan tray assembly with the sheet metal mounting brackets and slide it into place until the clasps on each side lock it into place.

3. Reconnect the fan power cable to the motherboard.

4. Perform the procedures described in Chapter 6.


5.3 Replacing the Power Supply

5.3.1 Removing the Power Supply

1. Perform the procedures described in Chapter 4.

2. Disconnect the power cable from the motherboard and pull the cable through the midwall.

3. Pull the fastener up on the front of the power supply and remove the power supply from the chassis (FIGURE 5-4).


FIGURE 5-4 Removing the Power Supply

Figure showing how to remove the power supply.


5.3.2 Installing the Power Supply

1. Unpack the replacement power supply.

2. Slide the power supply into the chassis and engage the two alignment pins in the rear of the chassis that mate with the power supply.

3. Push the fastener down on the front of the power supply to lock it into place in the chassis (FIGURE 5-5).


FIGURE 5-5 Installing the Power Supply

4. Redress the power cable through the midwall in the chassis and connect the cable to the motherboard.

5. Perform the procedures described in Chapter 6.

6. At the sc> prompt, issue the showenvironment command to verify the status of the power supply.


5.4 Replacing the Hard Drive Assembly

5.4.1 Removing the Single-Drive Assembly

1. Disconnect the drive cable from the data/power connector at the rear of the hard drive (FIGURE 5-6).

2. Pull the fasteners up on the rear of the single-drive assembly, and remove the single-drive assembly from the chassis (FIGURE 5-6).


FIGURE 5-6 Removing the Single-Drive Assembly

5.4.2 Installing the Dual-Drive Assembly

1. Unpack the drive assembly and the dual-drive cable.

The drive assembly should be shipped to you with one or two drives already installed in the assembly, depending on the type of drive assembly that you ordered.

2. Disconnect the drive cable from the data and power connectors on the motherboard and remove the drive cable from your server (FIGURE 5-7).


FIGURE 5-7 Location of Drive Power and Data Connectors on the Motherboard

Figure showing location of the data and power connectors on the motherboard.


3. Get the dual-drive cable that was shipped with the new drive assembly.

4. Plug the drive connectors into the data/power connectors at the rear of the hard drives.



Note - Make sure the connector is correctly oriented before plugging it into the data/power connector on the drives. When connecting the cable to the data/power connector on the lower drive in a dual-drive configuration, it may be easier to first remove the upper drive to get a clear view of the data/power connector on the lower drive.



5. Slide the drive assembly into the chassis until it mates with the front of the chassis.

FIGURE 5-8 shows a dual-drive assembly being inserted into the chassis. The process is the same for a single-drive assembly.


FIGURE 5-8 Installing the Drive Assembly

Figure showing how to install the drive assembly.


6. Push the fasteners down to lock the drive assembly into place in the chassis (FIGURE 5-8).

7. Redress the cable through the midwall in the chassis.

8. Route the drive data cables underneath the power supply cable.

9. Plug the power connector on the dual-drive cable to the power connector on the motherboard (FIGURE 5-7).

10. Plug the data connector marked J5003 on the cable to the J5003 data connector on the motherboard (the connector furthest from the power supply).

Refer to FIGURE 5-7 for the location of that connector.

11. Plug the data connector marked J5002 on the cable to the J5002 data connector on the motherboard (the connector closest to the power supply).

Refer to FIGURE 5-7 for the location of that connector.

12. Place the top cover on the chassis.

Set the cover down so that the cover hangs over the rear of the server by about an inch (2.5 cm).

13. Slide the cover forward until it latches into place.

14. Reinstall the server in the rack and apply power to the server.

Refer to the Sun SPARC Enterprise T1000 Server Service Manual for those instructions.

15. Label the hard drives, if necessary.

16. Upgrade the drive controller firmware, if necessary.

If you have an older version of the drive controller firmware, then you must upgrade the drive controller firmware to get full support for mirroring and other RAID features.

a. Determine the version of the drive controller firmware installed on your server by entering the following command:


# grep -i version /var/adm/messages

You should see output similar to the following:


Jun 7 13:23:16 wgs57-57 genunix: [ID 540533 kern.notice] SunOS Release 5.10
Version Generic_118833-08 64-bit
Jun 7 13:23:16 wgs57-57 mpt0 Firmware version v1.a.0.0 (IR)

then you have the latest drive controller firmware. Go to Step 17.
