Removing an Expansion Card
1. Open the system. See " Opening the System " in Troubleshooting Your System."
2. Disconnect any external cable(s) that are connected to the expansion card.
3. Remove the expansion-card retainer adjacent to the PCI slots. See Figure 6 -5 .
4. Grasp the expansion card and carefully pull it away from the riser-board connector.
If you are removing a SCSI controller card, disconnect the cables from the card that connects to the SCSI hard drives.
5. If you are permanently removing the card, replace the metal filler bracket over the empty card-slot opening.
6. Replace the expansion-card retainer.
7. Close the system. See " Closing the System " in "Troubleshooting Your System."
System Memory
The three memory module sockets are located on the system board adjacent to the power supply. See Figure 6 -1 .
You can upgrade the system memory by installing combinations of registered memory modules. If you receive an error message stating that maximum memory
has been exceeded, see "
Indicators, Messages, and Codes " for more information. You can purchase memory upgrade kits from Dell.
Memory Module Installation Guidelines
l If only one memory module is installed, it must be installed in the DIMM A socket.
l Install the memory modules with the largest capacity in DIMM A and the least capacity in DIMM C.
l Install the memory modules sequentially, which means that there can be no empty memory module sockets between the first and last installed socket.
CAUTION: See your System Information Guide for complete information about safety precautions, working inside the computer, and protecting
against electrostatic discharge.
NOTE: Filler brackets must be installed over empty expansion-card slots to maintain FCC certification of the system. The brackets also keep dust
and dirt out of the system and aid in proper cooling and airflow inside the system.
NOTE: The memory modules must be PC-2100 compliant.
