Replacing Cold-Swappable Components |
This chapter describes how to remove and replace field-replaceable units (FRUs) that must be cold-swapped in the Sun Netra T6340 Server Module.
The following topics are covered:
This section describes important safety information you need to know prior to removing or installing parts in the Sun Netra T6340 Server Module.
For your protection, observe the following safety precautions when setting up your equipment:
The following symbols might appear in this manual, note their meanings:

Caution - Hazardous voltages are present. To reduce the risk of electric shock and danger to personal health, follow the instructions. |
Electrostatic discharge (ESD) sensitive devices, such as the motherboard, hard drives, and memory cards require special handling.
Wear an antistatic wrist strap and use an antistatic mat when handling components such as drive assemblies, boards, or cards. When servicing or removing server module components, attach an antistatic strap to your wrist and the other end to a metal area on the chassis. Do this after you disconnect the power cords from the server module. Following this practice equalizes the electrical potentials between you and the server module.
Place ESD-sensitive components such as the motherboard, memory, and other PCB cards on an antistatic mat.
Before you can remove and replace internal components, you must perform the procedures in this section.
You can service the Sun Netra T6340 Server Module with the following tools:
Performing a graceful shutdown ensures that all of your data is saved and that the system is ready for restart. This section describes procedures for using the ILOM CLI or the ILOM web interface to shut down the system.
1. Log in as superuser or equivalent.
Depending on the nature of the problem, you might want to view the system status, the log files, or run diagnostics before you shut down the system. For more information, refer to:
Sun Integrated Lights Out Manager 3.0 Supplement for Sun Netra T6340 Server Modules, 821-0903. This document describes ILOM information specific to the UltraSPARC and the Sun Netra T6340 Server Module. It also provides command comparisons of the ALOM CMT and ILOM CLI command sets.
Refer to your Solaris system administration documentation for additional information.
3. Save any open files and quit all running programs.
Refer to your application documentation for specific information on these processes.
4. Shut down the Solaris OS using the shutdown (1M) command.
5. Use either the ILOM web interface, or the ILOM CLI, to finish the shut down sequence as described in the following sections.
You can also press the power button on the front of the server module to initiate a graceful shutdown.
From the ILOM web interface (FIGURE 4-1).
1. Select the System Information tab.
4. In the Actions menu, choose the “Prepare to Remove” option.
FIGURE 4-1 Powering Off the Server Module With the ILOM Web Interface
1. Switch from the system (host) console to the ILOM -> prompt by typing the #. (Hash-Period) key sequence.
2. At the ILOM -> prompt, type the server module power off command.
If the server module fails to power off at this point, you might want to force the issue.
1. At the ILOM -> prompt, type the set /SYS/ prepare_to_remove_action=true command and type y to confirm.
ILOM CLI, ILOM web interface, and ALOM-CMT command equivalents are described in Appendix D and Appendix E.
The blue blade ready to remove LED is illuminated.
The top white LED is the Locator LED. You can also set the white locator LED to blink:
Once you have located the server module, you can press the Locator LED to turn it off.
2. If a cable is connected to the front of the server module, disconnect it.
FIGURE 4-2 Disconnecting the Cable Dongle
Note - If you are using the older 4-cable dongle (UCP-4), do not use the RJ-45 connector with the Sun Netra T6340 Server Module. Use the DB-9 connector for serial connections. |
3. Open both ejector levers simultaneously (FIGURE 4-3).

Caution - Hold the server module firmly with both hands so that you do not drop it. The server module weighs up to approximately 19.8 pounds (9 kg). |
![]() |
Caution - Do not stack server modules higher than five units tall. They might fall and cause damage or injury. |
FIGURE 4-4 Stack Five Server Modules or Fewer
5. Set the server module on an antistatic mat.
6. Attach an antistatic wrist strap.
When servicing or removing server module components, attach an antistatic strap to your wrist and the other end to a metal area on the chassis.

This section describes how to remove and replace DIMMs.
LEDs indicate if a DIMM requires replacement.
![]() |
Caution - Ensure that you follow antistatic practices as described in Electrostatic Discharge Safety. |
1. Perform the procedures described in Common Procedures for Parts Replacement.
2. Locate the DIMMs that you want to replace (FIGURE 4-6).
The server module has a DIMM locate button on the motherboard. Press the DIMM locate button to illuminate the LEDs of the bad DIMMs.
FIGURE 4-6 DIMM Installation Rules
You can also use FIGURE 4-6 and TABLE 4-1 to identify the DIMMs that you want to remove.
FB-DIMM Installation Order[1] |
|||||
---|---|---|---|---|---|
Note - FB-DIMM names in ILOM messages are displayed with the full name, such as /SYS/MB/CMP0/BR0/CH0/D0. |
3. Note the DIMM locations so that you can install the replacement DIMMs in the same sockets.
4. Push down on the ejector levers on each side of the DIMM connector until the DIMM is released.
5. Grasp the top corners of the faulty DIMM and remove it from the system.
6. Place DIMMs on an antistatic mat.
See Memory Configuration for complete memory configuration and installation rules.
![]() |
Caution - The DIMM rules must be followed. The server module might not operate correctly if the DIMM rules are not followed. Always use DIMMs that have been qualified by Sun. |
1. Place the replacement DIMMs on an antistatic mat.
2. Remove any DIMM filler cards installed in the DIMM connectors in which you plan to install the new DIMMs.
3. Ensure that the connector ejector tabs are in the open position.
4. Line up a replacement DIMM with the connector.
Align the DIMM notch with the key in the connector.
a. Push each DIMM into a connector until the ejector tabs lock the DIMM in place.
b. Perform the procedures described in Finishing Component Replacement.
The service processor controls the host power and monitors host system events (power and environmental). The service processor holds a battery for maintaining the Real Time Clock (RTC), and a socketed EEPROM for storing the system MAC addresses (and therefore the host ID).
![]() |
Caution - The service processor card can be hot. To avoid injury, handle it carefully. |
1. Perform the procedures described in Common Procedures for Parts Replacement.
2. Lift up on the card ejector lever (FIGURE 4-9).
FIGURE 4-8 Removing the Service Processor
3. Slide the service processor out of the standoff bracket that holds the end of the service processor opposite the card connector.
4. Flip the service processor card over and place it on an antistatic mat.
5. Remove the system configuration PROM (NVRAM) (FIGURE 4-9) from the service processor card and place the PROM on an antistatic mat.
The socketed EEPROM attached to the Service Processor Card contains the system MAC addresses (and therefore the host ID).
The service processor also contains the ILOM configuration including the Service Processor IP addresses and ILOM user accounts, if configured. The MAC address (and host ID) will be lost unless the system configuration PROM (NVRAM) is removed from the old Service Processor card and installed in the replacement Service Processor Card. The ILOM configuration (IP address and user accounts) will be lost when the Service Processor Card is replaced.
The PROM does not hold the fault data, and the fault data will no longer be accessible when the service processor is replaced.
FIGURE 4-9 Removing the System Configuration PROM (NVRAM)
6. Retain the system configuration PROM to install it on the replacement service processor card.
1. Remove the replacement service processor from the package and place it on an antistatic mat.
2. Install the system configuration PROM (NVRAM) that you removed from the faulty service processor.
The PROM is keyed to ensure proper orientation.
FIGURE 4-10 Replacing the Service Processor
3. Insert the service processor edge into the standoff bracket and carefully align the service processor so that each of its contacts is centered on a socket pin (FIGURE 4-10).
4. Push both rubber buttons firmly and evenly until the service processor is firmly seated in the connector socket.
5. Perform the procedures described in Finishing Component Replacement.
