Increase System Memory With Additional DIMMs
Before You Begin
Before performing a memory upgrade procedure, become familiar with the memory configuration guidelines
described in DIMM Configuration Guidelines.
- Unpack the new DIMMs and place them on an antistatic mat.
- Remove the processor module from the server and remove the cover from the
processor module, if you have not already done so.
See Remove a Processor Module.
- At a DIMM slot that is to be upgraded, open the ejector tabs
and remove the filler panel.
Do not dispose of the filler panel. You may want to reuse it
if any DIMMs are removed at another time.
- Ensure that the ejector tabs on the connector that will receive the DIMM
are in the open position.
- Align the DIMM notch with the key in the connector.
Caution - Ensure that the orientation is correct. The DIMM might be damaged if the
orientation is reversed.
- Push the DIMM into the connector until the ejector tabs lock the DIMM
If the DIMM does not easily seat into the connector, check the DIMM's
- Repeat Step 3 through Step 6 until all DIMMs are installed.
- Place the cover back onto the processor module and insert the processor module
back into its slot in the server.
See Install a Processor Module
- Perform the following steps to verify that there are no faults:
- Set the virtual keyswitch to diag so that POST will run in Service mode.
-> set /SYS keyswitch_state=diag
Set ‘keyswitch_state' to ‘Diag'
- Power cycle the system.
-> stop /SYS
Are you sure you want to stop /SYS (y/n)? y
-> start /SYS
Are you sure you want to start /SYS (y/n)? y
Note - The server takes about one minute to power off. The ILOM console does
not indicate when the system is actually powered off.
- Switch to the system console to view POST output.
-> start /HOST/console
Watch the POST output for possible fault messages. The following output indicates that
POST did not detect any faults:
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 - The system might boot automatically at this point. If so, go directly to
Step e. If it remains at the ok prompt, go to Step d.
- If the system remains at the ok prompt, type boot.
- Return the virtual keyswitch to Normal mode.
-> set /SYS keyswitch_state=Normal
Set ‘ketswitch_state' to ‘Normal'
