Replacing System Components |
This chapter contains information and procedures for servicing the Sun Blade 6048 server module hardware, including component removal and replacement procedures.
The following topics are covered in this chapter:
The following procedures describe how to replace customer-replaceable unit (CRU) components:
You will need to replace a front fan module or power supply module if the module fails. A front fan module is located within each of the power supply modules, so you will need to remove the power supply associated with the fan module before replacing the module.
Do not leave a power supply slot vacant. Power supplies have integrated fans that will continue to supply cooling air even when the power supply is off. You can remove and replace a power supply from a powered-off system or from a powered-on system using a hot-swap procedure.
Use the following procedures to install a power supply into the corresponding vacant slot.
FIGURE 4-1 shows how to remove the power supplies and front fan modules.
Note - Remove only one power supply at a time. One power supply must be in the system at all times to supply power to the system. |
FIGURE 4-1 Removing a Power Supply and Front Fan Module
Note - You will need to replace the power supply that you removed within one minute to ensure proper system operation. |
1. In the front of the chassis, locate the power supply to be removed or the power supply that contains the front fan module that you plan to replace.
2. Press and hold the green button on top of the power supply handle frame.
3. Rotate the power supply handle away from the power supply and down.
4. Pull the power supply out of the chassis approximately 100 cm.
5. Choose the instructions below that correspond to the module that you want to replace:
a. You do not need to remove the power supply from the system any further.
Caution - The fan will continue spinning for a moment after the power supply is disconnected. Be careful not to insert a finger or other object into the fan while it is still spinning. |
b. With one hand, press together the two latches on top of the fan module and pull the module upward.
c. Grasp the module with the other hand as soon as possible and remove the module from the power supply.
FIGURE 4-2 shows how to install the power supplies.
FIGURE 4-2 Installing a Power Supply Module and Front Fan Module
1. If you are replacing a front fan module, insert the fan module into the power supply.
2. If necessary, pull the power supply handle out and away from the power supply.
3. Align the power supply unit with the power supply slot.
Ensure that the power supply unit is facing up and that the five LED holes appear on the left when you are installing the power supply module.
4. In a smooth motion, slide the power supply into the power supply slot until the unit engages with the internal connectors.
You can remove and replace a server module (blade) from a powered-off system or from a powered-on system using hot-plug procedures.
Caution - Do not operate system with empty slots. Always insert a filler into an empty slot to reduce the possibility of module shutdown. |
1. Initiate an orderly shutdown of the operating system.

FIGURE 4-5 Installing a Server Module
3. Align the server module with the vacant server module slot. Ensure the following:
4. Slide the server module into the vacant server module chassis slot.
As the ejectors make contact with the chassis, the bottom lever will start to rise, and the top lever will start to lower.
5. Simultaneously close the ejector levers at the top and bottom of the server module (lower the top ejector and raise the bottom ejector) until the levers clamp in place against the front of the server module.
As the ejector levers are closed, the server module moves back to engage with the chassis.
6. Verify that the server module is powered on and operational.
After you insert a server module into a powered-on system, the server module’s internal service processor (SP) is brought online automatically, and the server module is powered on by default.
7. For each remaining server module to be installed, repeat Step 1 through Step 6.
The front indicator module (FIM) is located in the front of the chassis. You can remove and replace a FIM from a powered-off system or from a powered-on system using hot-plug procedures.

2. Slide the NEM into the vacant NEM chassis slot until you feel it stop.
3. Complete the installation by closing the ejector levers to secure the NEM in the chassis.
A pair of PCI EMs is assigned to each server module in the chassis. All PCI EMs connect to a chassis midplane. The midplane provides an interconnect between the server modules and the PCI EMs installed in the chassis. The midplane connections between the server module and the PCI EM are logically defined by the midplane as shown in FIGURE 4-10.
FIGURE 4-10 PCI EM to Server Module Correspondence
If the PCI Express Module (PCI EM) fails or if you choose to change the I/O configuration, you will need to replace a PCI EM. You can remove and replace a PCI EM from a powered-on system using a hot-swap procedure, as well as from a powered-off system.
Caution - If you are not immediately replacing the PCI EM, install an PCI EM filler panel to ensure proper system operation. |
Note - Check your server module operating system documentation to determine if software commands are needed for the system to recognize PCI EM removal or installation. |
FIGURE 4-11 shows how to remove the PCI EMs.
1. In the rear of the chassis, locate the PCI EM that you want to remove.
If the amber Attention indicator on a PCI EM is lit, this indicates a problem with the PCI EM, and you might choose to replace it. Otherwise, if you want to change the I/O configuration, you can choose any PCI EM to replace.
2. If you are hot-plugging the PCI EM, prepare the operating system.
You will need to prepare for PCI EM removal through the associated server module operating system. See the server module (blade) or operating system documentation for more information.
3. Verify that the PCI EM Power indicator is off.
If you have successfully prepared the PCI EM for a hot-removal, the Power indicator turns off.
4. Place one finger on top of ejector-lever handle.
5. Pull the ejector lever toward you to pull the PCI EM forward until you can pull the rest of the module out by hand.
