9: Servicing the System
Warning:
The system is always on when connected to AC power. Before performing this task, disconnect the system’s power cord from its AC power outlet.
1.
If replacing a DIMM, press the DIMM socket release tabs outward, away from each other; then grasp the top edge of the DIMM and pull it out of the socket.
2. Remove the new DIMM from its antistatic package. Verify the DIMM has gold-plated fingers that match the gold-plated socket contacts, and the slot keys on the DIMM match the slot keys in the DIMM socket.
3. Orient the DIMM so that the notches match the keys in the socket.
4. Push gently straight down until the release tabs snap into place.
5. Restart the system for the BIOS to detect the new memory.
For more information on DIMMs, DIMM sockets, and system memory configurations, see the System Board Guide.
Processor Bus Terminator
On a system with only one processor, a processor bus terminator occupies the other processor slot on the system board. This module ensures proper termination for the processor bus; without it, the system will not function. When you add a second processor, you must remove this module and replace it with the new processor.
Warning:
The system is always on when connected to AC power. Before performing this task, disconnect the system’s power cord from its AC power outlet.
To remove the processor bus terminator:
Carefully pull the terminator card out of the processor slot.
For more information on the processor bus terminator, see the System Board Guide.
