NOTE: After installing a new power supply, allow several seconds for the system to recognize the power supply and determine whether it is working properly. The power-on indicator will turn green to signify that the power supply is functioning properly (see Figure 2-4).

2. Close the bezel (see "Replacing the Bezel" in "Troubleshooting Your System").
   
   

Expansion Cards

The system includes seven expansion slots. The expansion cards are installed on the system board (see Figure A-3 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, see Figure A-3. Table 6-1 lists the PCI bus and operating speed for each expansion-card slot.

Table 6-1. Expansion Slot Speeds

Slot	Bus	Operating Speed
1	0	33 MHz
2	5	33, 66, or 100 MHz
3	5	33, 66, or 100 MHz
4	4	33, 66, or 100 MHz
5	4	33, 66, or 100 MHz
6	3	33, 66, 100, or 133 MHz
7	2	33, 66, 100, or 133 MHz
NOTE: If you are using expansion cards of different operating speeds, you should install the fastest card in slot 7 and the slowest card in slot 1. NOTE: For the full name of an abbreviation or acronym used in this table, see "Abbreviations and Acronyms."

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.

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

Order	Device or Slot
1	Expansion slot 1
2	Embedded remote access components
3	Video
4	Integrated Gigabit NIC
5	Expansion slot 7
6	Expansion slot 6
7	Expansion slot 4
8	Expansion slot 5
9	Expansion slot 4
10	Expansion slot 3
11	Expansion slot 2
12	Optional integrated RAID controller on the system board
13	Integrated SCSI controller on the system board
NOTE: For the full name of an abbreviation or acronym used in this table, see "Abbreviations and Acronyms."
