4: Installing and Removing Customer-Replaceable Units
Removing a DIMM
To remove a DIMM, follow these steps:
1. Power off the Silicon Graphics Prism platform. For powering off instructions, see
“Powering Off Manually” on page 25.
2. Disconnect all of the cables at the rear of the module.
Warning: Components may be hot. To avoid injury, allow the components to cool
for approximately five minutes before you proceed with these instructions.
3. Remove the two screws that secure the module to the front rails of the rack. For
shelf-mounted modules, remove the two screws at the rear of the unit.
4. With shelf-mounted rails, use two people to slide the module out and move it to a
stable work surface. With optional slide rails, pull the module from the rack until it
is stopped by the safety latches.
5. Open the top cover as described in “Opening the Cover” on page 74.
6. Remove the DIMM, as follows (see Figure 4-24 and Figure 4-26):
Note: For guidelines on removing or replacing the DIMMs, make sure to read the
introductory material in “Removing and Replacing Memory DIMMs” on page 107
and see Figure 4-23 on page 108.
a. Push out and down on the two ejector latches (located at each end of the DIMM
socket) to disengage the DIMM from its connector.
b. Carefully grasp the DIMM and pull it up and out of the guide rails.
Note: Hold the DIMM only by its edges. Be careful not to touch its components
or gold edge connectors.
c. Place the DIMM on an ESD-safe surface.
7. If you are installing a new DIMM, proceed to “Installing a DIMM Group” on
page 109. If you are not installing a new DIMM, proceed to the next step.
8. Close the top cover as described in “Closing the Cover” on page 80.
