▼ To Remove FB-DIMMs
Caution – Ensure that all power is removed from the server before removing or
installing FB-DIMMs. You must disconnect the power cables before performing this
procedure.
1. Review Section 4.1.1, “FB-DIMM Guidelines” on page 4-3 for memory
configuration information.
2. Prepare the server for service.
a. Power off the server.
See Section 2.4, “Powering Off the Server” on page 2-3.
b. Disconnect the power cord (or cords) from the power supply (or supplies).
See Section 2.4, “Powering Off the Server” on page 2-3.
c. Extend the server into the maintenance position.
See Section 2.5, “Extending the Server to the Maintenance Position” on
page 2-5.
d. Attach an antistatic wrist strap.
See Section 2.7, “Performing Electrostatic Discharge and Antistatic Prevention
Measures” on page 2-8.
e. Remove the top cover.
See Section 2.8, “Removing the Top Cover” on page 2-10.
3. If you are replacing a faulty FB-DIMM, press the “Remind” button to activate
the FB-DIMM status LEDs after power is removed.
All faulty FB-DIMMs are indicated with an amber LED on the motherboard, so
that you can install the replacement FB-DIMM in the same location.
Tip – Make a note of the faulty FB-DIMM location.
4. Push down on the ejector tabs on each side of the FB-DIMM until the
FB-DIMM is released (
FIGURE 4-4).
5. Grasp the top corners of the faulty FB-DIMM and remove it from the server.
