Third 2 and 8 3 and 5
Fourth 4 and 6 9 and 11
Fifth None 2 and 8
Sixth None 13 and 15

Note: The DIMM pairs must be identical in size, type, and rank count.
Attention: DIMMs or DIMM fillers must occupy DIMM connectors 1, 2, 13, 14,
15, and 16 for proper cooling.
To install a DIMM, complete the following steps:
1. Before you begin, read “Safety” on page v and “Installation guidelines” on
page 17.
2. Read the documentation that comes with the DIMMs.
3. If the blade server is installed in a BladeCenter unit, remove it (see
“Removing the blade server from the BladeCenter unit” on page 19 for
instructions).
4. Carefully lay the blade server on a flat, static-protective surface.
5. Open the blade server cover (see “Removing the blade server cover” on page
20 for instructions).
6. If an expansion unit is installed and you are installing DIMMs on the system
board, remove the expansion unit (see “Removing an optional expansion unit”
on page 23).
7. Locate the DIMM connectors (see “Blade server connectors” on page 15).
Determine which DIMM connector you will be installing memory into.
8. If a DIMM filler or another memory module is already installed in the DIMM
connector, remove it (see “Removing a memory module” on page 28).
Note: A DIMM or DIMM filler must occupy each DIMM socket before the
blade server is turned on.
9. If you are installing a DIMM in DIMM connector seven through twelve, use
your fingers to lift the DIMM access door.
