This section describes important safety information you need to know prior to removing or installing parts in the Sun Blade T6300 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 - There is a risk of personal injury and equipment damage. To avoid personal injury and equipment damage, follow the instructions. |
Caution - Hot surface. Avoid contact. Surfaces are hot and might cause personal injury if touched. |
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 then 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 Blade T6300 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.
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:
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.
5. Switch from the system console to the ALOM CMT sc> prompt by typing the #. (Hash-Period) key sequence.
6. At the ALOM CMT sc> prompt, issue the poweroff command.
Note - You can also use the Power button on the front of the server module to initiate a graceful system shutdown. Use a paper clip to press this button. |
Refer to the Advanced Lights out Management (ALOM) CMT v1.3 Guide, 819-7981, for more information about the ALOM CMT poweroff command.
1. To perform an orderly shutdown, run the removeblade command:
The top white LED is the Locator LED. Once you have located the server module, you can press the Locator LED to turn it off. Or you can use the setlocator off command to reset the LED.
2. If a cable is connected to the front of the server module, disconnect it.

The Sun Blade T6300 server module has eight slots that hold DDR-2 memory DIMMs in the following DIMM sizes:
The Sun Blade T6300 server module performs best if all eight connectors are populated with eight DIMMs. This configuration also enables the system to continue operating even when a DIMM fails, or if an entire channel fails.
Due to interleaving rules for the CPU, the system will operate at the lowest capacity of all the DIMMs installed. Therefore, it is ideal to install eight identical DIMMs (not four DIMMs of one capacity and four DIMMs of another capacity).
Caution - The following 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. |
DIMMs are installed in groups of four, with four DIMMs of the same capacity (FIGURE 4-6).
If the DIMMs are not properly configured, the system issues a message and the system does not boot.
For more information about DIMMs see Section 2.1.1.4, Memory Fault Handling.
The DIMM ejectors have LEDs that indicate if a DIMM requires replacement.
Caution - Ensure that you follow antistatic practices as described in Section 4.1.2, Electrostatic Discharge Safety. |
1. Perform the procedures described in Section 4.2, Common Procedures for Parts Replacement.
2. Locate the DIMMs (FIGURE 4-6) that you want to replace.
The server module has a DIMM test button on the motherboard. Press the DIMM Locate button to illuminate the ejectors of the bad DIMMs.

a. Push each DIMM into a connector until the ejector tabs lock the DIMM in place.
a. Perform the procedures described in Section 4.6, Finishing Component Replacement.
4. Access the ALOM CMT sc> prompt.
At the console, issue the #. key sequence:
5. Run the showfaults -v command to determine how to clear the fault.
The method that you use to clear a fault depends on how the fault is identified by the showfaults command.
Go to Step 8.
Run the enablecomponent command to enable the FRU:
6. Perform the following steps to verify that there are no faults:
a. Set the virtual keyswitch to diag so that POST will run in service mode.
c. Switch to the system console to view POST output.
Watch the POST output for possible fault messages. The following output is a sign that POST did not detect any faults:
. . 2000-02-11 21:33:43.045 0:0> POST Passed all devices. 2000-02-11 21:33:43.272 0:0>POST: Return to VBSC. 2000-02-11 21:33:43.280 0:0>Master set ACK for vbsc runpost command and spin...... |
d. Issue the Solaris OS fmadm faulty command.
No memory or DIMM faults should be displayed.
If faults are reported, refer to FIGURE 2-1 to diagnose the fault.
7. Access the ALOM CMT sc> prompt.
8. Run the showfaults command.
