Revision1.11

3.4 System IO

The server board Input/Output features are provided via the embedded features and

functions of several onboard components including the Integrated I/O Module (IIO) of the

Intel

Xeon

E5-2600 v3 processor, the Intel

C610 series chipset, the Intel

Ethernet controller

I350 or X540, and the I/O controllers embedded within the Emulex* Pilot-III Management

Controller.

3.4.1 PCI Express* Support

The integrated I/O module incorporates the PCI Express* interface and supports up to 40

lanes of PCI Express. The Intel

Server Board S2600CW supports six PCI-e slots from two

processors and PCH:

 From PCH:

- Slot 1: PCIe Gen II x4

 From the first processor:

- Slot 5: PCIe Gen III x16/x8 electrical with x16 physical connector. Electrical x16 for

S2600CW2 or S2600CWT, electrical x8 for S2600CW2S or S2600CWTS

- Slot 6 PCIe Gen III x16 electrical with x16 physical connector

 From the second processor:

- Slot 2: PCIe Gen III x16 electrical with x16 physical connector

- Slot 3: PCIe Gen III x8 electrical with x8 physical connector

- Slot 4: PCIe Gen III x16 electrical with x16 physical connector

The server board supports up to three full length full height double-width PCIe cards on slot 2,

slot 4, and slot 6.

Standard PCIe slots can provide up to 25W power. PCIe slot 2, 4, and 6 can provide up to 75W

power. The higher power requirement needs direct power cables from power supplies.

Note:

1. Both CPU power connectors need to be connected in order for all the PCIe slots to work.

2. While PCIe slot 5 is also an x16 connector, only 3 x16 PCIe slots on the board can support

up to 75W slot power at a time. This is a configuration limitation based on the System

Power budget. When used as riser slot, slot 6 can each provide up to 75W power to the riser.

Below is a list of possible power configurations supporting different high power PCIe cards:

 x16 150W card

- 75W from PCIe slot and 75W from PSU direct cable attach: 75W (2x3 conn)

 x16 225W card
