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. Figure 5-37 Identifying expansion card slots The following table describes the workstation PCIe card slots. Table 5-6 PCI slots Slot Type Slot power (Maximum) 1 PCIe2 - x8(4) 25W 2 PCIe2 - x16 75W 3 PCIe - x8(4) 25W 4 PCIe2 - x16 75W 5 PCI 32/33 25W 6 PCI 32/33 25W 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.
