 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.

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.

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.

To remove an expansion card:

Disconnect power from the workstation (see 

Remove the side access panel (see
