Before you begin this memory upgrade procedure, become familiar with the memory configuration guidelines described in FB-DIMM Configuration Guidelines for Sun SPARC Enterprise T5140 Servers.
Caution - Ensure that all power is removed from the server before installing FB-DIMMs or damage to the FB-DIMMs might occur.
Caution - You must disconnect the power cords from the system before performing this procedure.
Store the filler panels in a safe place. You will reuse the filler panels if you remove FB-DIMMs in the future.
Align the FB-DIMM notch with the key in the connector. This alignment ensures that the FB-DIMM is oriented correctly.
Figure 68 Installing FB-DIMMs
Note - If the FB-DIMM does not easily seat into the connector, it may not have the correct orientation. If the orientation is reversed, damage to the FB-DIMM might occur.
The air duct snaps into position above the CMP and memory modules.
Note - As soon as the power cords are connected, standby power is applied. Depending on how the firmware is configured, the system might boot at this time.
-> set /SYS/keyswitch_state=Diag Set ‘keyswitch_state’ to ‘Diag’
-> stop /SYS Are you sure you want to stop /SYS (y/n)? y Stopping /SYS -> start /SYS Are you sure you want to start /SYS (y/n)? y Starting /SYS
Note - The server takes about one minute to power off. The ILOM console does not indicate when the system is actually powered off.
-> start /SYS/console
Watch the POST output for possible fault messages. The following output is a sign that POST did not detect any faults:
. . . 0:0:0>INFO: 0:0:0> POST Passed all devices. 0:0:0>POST: Return to VBSC. 0:0:0>Master set ACK for vbsc runpost command and spin...
Note - Depending on the configuration of ILOM POST variables and whether POST detected faults or not, the system might boot, or the system might remain at the ok prompt. If the system is at the ok prompt, type boot.
-> set /SYS keyswitch_state=Normal Set ‘ketswitch_state’ to ‘Normal’
