Installing rp5470 DIMMs
DIMMs for the rp5470 system are installed in memory carriers instead of the system board, as are the other
rp54xx systems. However, rp5470 memory carriers are also located on the system board, so the method for
opening and closing the system is the same. Procedures for removing and replacing the server top and baffle
are listed below, without the pictures shown in the section titled, "Installing rp5400 and/or rp5450 DIMMs."
If you wish to reveiw the pictures, please refer to the aforementioned section.
Step 1. Power down and unplug the rp54xx server.
NOTE
Step 2. Make the top of the server accessible for service.
Step 3. Loosen the captive T-15 screws that hold the top cover in place, then grasp the strap handle, raise
the cover slightly, and pull the cover toward the front of the server to free the cover tabs from the
slots in the chassis. The air baffle will be exposed.
Step 4. Loosen the four (4) captive T-15 screws on the air baffle. Grasp the two handles on the baffle, and
lift and remove the baffle.
Step 5. Observe Electrostatic Discharge (ESD) precautions.
Step 6. Refer to the following graphic for Memory Carrier locations.
