Air baffles
3. Locate the DIMM connectors (see “System-board connectors” on page 16).
Determine which DIMM you want to remove from the compute node.
Note: You might have to remove the mezzanine.
Attention: To avoid breaking the retaining clips or damaging the DIMM
connectors, handle the clips gently.
4. Make sure that both retaining clips on the DIMM connector from which you
are removing the DIMM are in the open position.
Note: You might have to remove the mezzanine.
5. Pull the DIMM out of the connector.
6. If you are not immediately replacing the DIMM, install the air baffle.
Attention:
v Install the air baffles with the arrow indicating air flow direction pointing to
the rear of the compute node.
v To maintain proper system cooling, do not operate the compute node
without air baffles installed over the DIMM connectors.
What to do next
If you are instructed to return the DIMM, follow all packaging instructions, and
use any packaging materials for shipping that are supplied to you.
Installing a DIMM
Use this information to install a DIMM.
Before you begin
Before you install a DIMM, complete the following steps:
1. Read “Safety” on page v and “Installation guidelines” on page 487.
2. Read the documentation that comes with the DIMMs.
3. If the compute node is installed in an IBM Flex System chassis, remove it (see
“Removing a compute node from a chassis” on page 489 for instructions).
4. Carefully lay the compute node on a flat, static-protective surface, orienting the
compute node with the bezel pointing toward you.
