DIMM 6, DIMM 7
If two processors are installed, memory sparing is set up as follows:
To install a DIMM, complete the following steps:

DIMM 6, DIMM 7
DIMM 10, DIMM 11
DIMM 14, DIMM 15
Note: If all DIMMs are of the same size, the memory reference code (MRC) sets sparing in the farthest DIMM
pair. Otherwise, the largest DIMM pair is set aside as spare.
To install a DIMM, complete the following steps:
Step 1.
Before you begin, read "Safety" on page iii and "Installation guidelines" on page 23.
Step 2.
Locate the DIMM connectors (see "Blade server connectors - BladeCenter HX5" on page 20).
Determine the DIMM connector into which you will be installing memory.
Step 3.
If another memory module is already installed in the DIMM connector, remove it (see "Removing a
DIMM - BladeCenter HX5" on page 43).
Step 4.
Touch the static-protective package that contains the DIMM to any unpainted metal surface on the
BladeCenter unit or any unpainted metal surface on any other grounded rack component in the
rack in which you are installing the DIMM for at least two seconds; then, remove the DIMM from its
package.
Step 5.
To install the DIMMs, repeat the following steps for each DIMM that you install:
