The following list provides PCI slot assignment information for the system’s PCI
buses, RAID controllers, NICs, and DRAC.
•PCI buses
—PCI bus 1: PCI slots 1 and 2 are 64-bit, 33/66-MHz.
—PCI bus 2: PCI slots 3 through 6 are 64-bit, 33-MHz.
—PCI bus 3: PCI slot 7 is 32-bit, 33-MHz.
•RAID controllers
—RAID controllers can be installed in any available 64-bit, 33-MHz or 32-bit,
33-MHz PCI slot.
—If you use multiple RAID controllers and there are available slots, Dell recom-
mends installing the RAID controllers on separate PCI buses to balance the
load on the system.
•NICs
—You can install NICs in any available PCI slot.
—Dell recommends that Giganet cLAN adapters be installed in 64-bit slots.
•DRAC
—If you are currently using a DRAC or plan to use one in the future, install it in
PCI slot 7.
NOTE: To make sure that the SCSI or RAID controller attached to the boot drives
initializes first, you might have to change the scan order of the PCI bus, if the BIOS
supports this option, or change the order of the RAID, NIC, and DRAC. Performing
these tasks ensures that the Windows operating system numbers the boot drives in
the proper sequence.
