The ESD wrist strap must be connected to an unpainted metal surface until the service procedure is
completed, and if applicable, until the service access cover is replaced.
Attention:
• Attach an electrostatic discharge (ESD) wrist strap to the front ESD jack, to the rear ESD jack,
or to an unpainted metal surface of your hardware to prevent the electrostatic discharge from
damaging your hardware.
• When you use an ESD wrist strap, follow all electrical safety procedures. An ESD wrist strap is
used for static control. It does not increase or decrease your risk of receiving electric shock
when using or working on electrical equipment.
• If you do not have an ESD wrist strap, just prior to removing the product from ESD packaging
and installing or replacing hardware, touch an unpainted metal surface of the system for a
minimum of 5 seconds. If at any point in this service process you move away from the
system, it is important to again discharge yourself by touching an unpainted metal surface for
at least 5 seconds before you continue with the service process.
2. Depending on the memory location, you might need to remove the system processor air baffles.
Carefully unsnap and lift the processor air baffle from the system.
3. Depending on the memory location, you might need to remove one or both PCIe risers.
For information, see “Removing a PCIe adapter from the 9006-12P system” on page 29.
4. Remove the memory DIMM.
a) Locate the memory DIMM that you want to remove.
b) Unlock the memory DIMM by simultaneously pushing the locking tabs away from the memory
DIMM, in the direction that is shown in Figure 19 on page 27. Be sure to unlock both tabs at the
same time. The lever action of opening the tabs pushes the memory DIMM out of the slot.
c) Hold the memory DIMM by the edges and pull it out of the slot.
