The expansion card slots are on separate buses. To identify expansion slots, see Expansion-CardRiser-Board Components and PCIe Buses.

Expansion Card Installation Guidelines

Observe the following notes and guidelines regarding the expansion-card slots:

•The expansion-card slots are not hot-pluggable.

•Although slot 2 is physically a PCIe x8 connector, it functions only as a PCIe x4 lane slot.

•Slots 1 and 3 support full-length expansion cards; slots 2 and 4 support half-length expansion cards.

•The system supports up to two RAID expansion cards to manage external storage.

Installing an Expansion Card

CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team.
