Step 1240-11
Attention: If only one quad of DIMMs is on the processor card, you must have at
least one replacement DIMM of the same size and speed as the DIMMs that are on the
card.
If there were two quad of DIMMs on the processor card, but they are not the same size,
your must have at least one replacement DIMM of the same size and speed as the
DIMMs in the quad that is failing.
If there were two quad of DIMMs on the processor card, and they are the same size
and speed, DIMMs from the good quad can be used when isolating the failing DIMM in
the suspect quad.
1. Turn off the power. Remove the power cord.
2. Remove one of the DIMMs on the processor card and install the replacement DIMM
or another known good DIMM.
3. Reattach the power cord. Wait for
OK
in the operator panel.
4. Turn on the power. Attempt to boot to the SMS menus. (The system may stop with
an 8-digit error code before it reaches the SMS menus.)
5. Power down the system using the white button. After the
OK
appears in the operator
panel, look at the memory configuration/deconfiguration menu.
Are any DIMMs deconfigured?
NO The DIMM that was just removed was the failing DIMM; replace it.
Enable memory repeat gard if necessary.
