3. Reconnect all expansion-card cables.
   
   
4. Replace the cover (see "Replacing the Cover" in "Troubleshooting Your System").
   
   

Expansion Cards

The system includes three expansion slots. The expansion cards are installed on the system's riser board (see Figure A-4 to identify the expansion slots).

Expansion Card Installation Guidelines

You can install expansion cards of different operating speeds on the same bus; however, the bus will operate at the slowest operating speed of the cards on that bus. For example, if one card on the bus has an operating speed of 66 MHz and the other card has an operating speed of 100 MHz, the bus will only operate at 66 MHz.

To identify expansion slots and PCI buses, see Figure A-4. Table 6-1 lists the PCI bus and operating speed for each expansion-card slot.

Table 6-1. Expansion Slot Speeds

PCI Bus Scan Order

The system's BIOS scans and numbers PCI buses and devices during startup. Expansion slots are scanned according to the host bus ordering, not by the slot numbers. See Table 6-2 for the order in which the expansion slots and embedded PCI devices are scanned. Figure A-4 provides a diagram of buses and expansion slots.

An additional factor affects the assignment of PCI bus numbers: an expansion card may have its own PCI bridge chip which requires the assignment of a bus number for the card as well as one for the bridge. A particular expansion card may have two PCI bridge chips which would result in three sequential PCI bus numbers all assigned in the same expansion slot.

If you install expansion cards, you may have some difficulty in directly determining the bus number of a controller on a particular expansion card. However, the PCI bus scan order listed in Table 6-2 can help determine the relative numbering of PCI buses within the expansion slots. For example, a PCI controller residing in expansion slot 3 will never have a lower bus number than one in slot 2 because slot 2 precedes slot 3 in the scan order.

Table 6-2. PCI Bus Scan Order

Memory Modules

The six memory module connectors on the system board can accommodate 256 MB to 6 GB of registered memory modules. The memory module connectors are arranged in pairs which consist of three banks (DIMM A – DIMM C).

Memory Upgrade Kits

The system is upgradable to 6 GB by installing combinations of 128-, 256-, 512-MB, and 1-GB registered DDR SDRAM modules. You can purchase memory upgrade kits as needed.

NOTE: The memory modules must be PC-1600 compliant.

Memory Module Installation Guidelines

Starting with the connector nearest the power supplies, the memory module connectors are labeled "DIMM A1" through "DIMM C2" (see Figure A-3). When you install memory modules, follow these guidelines:

• You must install memory modules in matched pairs.
  
  
• Install a pair of memory modules in connector DIMM A1 and A2 before installing a second pair in connectors B1 and B2, and so on.
  
  

Table 6-3 lists several sample memory configurations based on these guidelines.
