HP VA799UT 799UT#ABA manual Expansion card slot description, Removing an expansion card

Expansion card

NOTE: Read Warnings and cautions on page 59 before servicing this component.

PCIe I/O slots can support other PCIe cards with less bus bandwidth than what is physically defined for the slot.

Expansion card slot description

NOTE: The x1, x4, x8, and x16 designators describe the number of signals that an expansion card, or an expansion card slot, can accommodate. For example, x4(x8) means that a card designed to receive four signals electrically can be placed in a slot designed for an eight-signal card.

Use the following table to determine PCIe card compatibility.

Table 5-6Workstation PCIe compatibility matrix

Slot	Mechanical compatibility	Electrical compatibility
1	x8 connector, open-ended	PCIe2 (x4)
2	x16 connector	PCIe2 (x1, x4, x8, x16)
3	x8 connector, open-ended*	PCIe (x4)
4	x16 connector	PCIe2 (x1, x4, x8, x16)

*This slot is open-ended so a PCIe x16 card can be inserted.

Slots one, two, and four are PCIe GEN2 slots.

Graphics cards greater than 75 watts require the use of an auxiliary power cable adapter.

Removing an expansion card

To remove an expansion card:

1.Disconnect power from the workstation (see Predisassembly procedures on page 66).

2.Remove the side access panel (see Removing the side access panel on page 69).
