P1-C2 DIMM 2
P1-C3 DIMM 3
P1-C4 DIMM 4
P1-C5 DIMM 5
P1-C6 DIMM 6
P1-C7 DIMM 7
P1-C8 DIMM 8
A memory error occurred.
1.
Verify that the DIMM indicated by the lit
LED is a supported memory module, as
described on the ServerProven Web site.
2.
Reseat the DIMM indicated by the lit LED,
as described in “Installing a memory
module” on page 245.
3.
Replace the DIMM indicated by the lit
LED, as described in “Removing a memory
module” on page 244 and “Installing a
memory module” on page 245.
Note:
Multiple DIMM LEDs do not
necessarily indicate multiple DIMM failures. If
more than one DIMM LED is lit, reseat or
replace one DIMM at a time until the error
goes away. See the online information or the
Hardware Maintenance Manual and
Troubleshooting Guide
or
Problem Determination
and Service Guide
for your BladeCenter unit for
further isolation.
