Dell PowerEdge 1650 - Manual (Page 44)

To install a memory module, perform the following steps:
1. Press down and outward on the ejectors on the memory module socket, as shown in Figure 6 -5 , to allow the memory module to be inserted into the
socket.
Figure 6-5. Installing a Memory Module
2. Align the memory module's edge connector with the slot in the center of the memory module socket, and insert the memory module into the socket (see
Figure 6 -5 ).
The memory module socket has two alignment keys that allow the memory module to be installed in the socket in only one way.
3. Press down on the memory module with your thumbs while pulling up on the ejectors with your index fingers to lock the memory module into the socket
(see Figure 6 -5 ).
When the memory module is properly seated in the socket, the ejectors on the memory module socket should align with the ejectors on the other
sockets with memory modules installed.
4. Repeat steps 1 through 3 of this procedure to install the remaining memory modules.
5. Perform steps 4 through 7 of " Performing a Memory Upgrade ."
Removing Memory Modules
To remove a memory module, press down and outward on the ejectors on each end of the socket until the memory module pops out of the socket (see
Figure 6 -6 ).

Installing Microprocessors
To take advantage of future options in speed and functionality, you can add a second microprocessor or replace either the primary or secondary
microprocessor.
Each microprocessor and its associated level 2 (L2) cache memory are contained in a FC-PGA2 package that is installed in a ZIF socket on the system board.
The following subsection describes how to install or replace the microprocessor in either the primary or secondary microprocessor connector.
Adding or Replacing a Microprocessor
In addition to the ZIF socket for the primary microprocessor on the system board, there is a second ZIF socket to accommodate a secondary microprocessor.
The secondary microprocessor must have the same operating frequency and cache size as the primary microprocessor.
The following items are included in the microprocessor upgrade kit:
l A microprocessor chip
l A heat sink
l A retention clip
NOTICE: The second microprocessor must be of the same type and speed as the first microprocessor.
