Expansion card slot identification
This section identifies and describes workstation expansion card slots, and presents card configuration
information.
Slot identification and description
The following figure identifies workstation expansion card slots.

NOTE:
The x1, x4, x8, and x16 designators describe the mechanical length of the slot. The number
in parentheses shows how many electrical PCIe lanes are routed to the expansion slot. For example,
x16(8) means that the expansion slot is mechanically a x16 length connector, with eight PCIe lanes
connected. A x16 graphics card runs at the bandwidth of the slot it is plugged into.
Slots one and three use open-ended PCIe connectors, so a PCIe x16 card can be inserted. Graphics
cards greater than 75 watts require the use of an auxiliary power cable adapter.
