Installing a CPU/Memory Module
Caution –
The system supplies power to the CPU/memory module even when the
system is powered off. To avoid personal injury or damage to the system, you must
disconnect all AC or DC power cables before servicing the CPU/memory module.
1. Identify the CPU/memory module slot into which you want to install the
CPU/memory module.
The CPU/memory module slots are marked on the bottom of the CPU cage.
2. Inspect the CPU/memory module connector and the motherboard connector for
foreign objects.
3. Ensure that the ejector levers on the CPU/memory module are rotated up to a 90-
degree angle.
4. Slide the CPU/memory module into the guides in the CPU cage.
Slide the CPU/memory module into the chassis until the connectors on the module
begin to engage the socket on the motherboard.
5. Push down on both ejector levers, simultaneously, until the levers are completely
pressed into their slots.
Note – Do not press down directly on the CPU/memory module. Let the levers
press the CPU/memory module into its socket.
6. Tighten the two Phillips No. 2 captive screws that secure the CPU/memory
module to the CPU cage.
7. Repeat Step 1 through Step 6 for every CPU/memory module that you want to
install.
If you are installing several CPU/memory modules at one time, once you have
installed the final CPU/memory module, you should press down on each of the
CPU/memory modules one last time to verify that they are all fully seated.
8. Replace the top cover.
See “Installing the Top Cover” on page 31 .
9. Power on the system.
