3.11.3 Graphics Card Population Guide
Table 14. Graphics Card Population
Graphics Card Support
One graphics card with maximum 300-W power in PCI Express* slot 6, or up to two graphics cards with maximum 150-
W power in PCI Express* slots 4 and 6.
Keep PCI Express* Slot 3 empty for optimal air flow when populating a graphics card in PCI Express* slot 4.
Note: Please follow the installation guide accompanying your graphics card for the power
connection and using the power adapter cable accompanying your graphics card (if any).
Graphics cards with power greater than 75-W must be self-cooled with exhaust out the back of
the chassis.
ATI* CrossFire* technology is considered fully validated by Intel workstation validation, Intel
validation may not meet all of ATI prescribed CrossFire* test requirements (if any).
3.12 Network Interface Controller (NIC)
The Intel
®
Workstation System SC5650SCWS provides dual onboard LAN ports with support for
10/100/1000 Mbps operation. The two LAN ports are based on the onboard Intel
®
82575EB
controller, which is a single, compact component with two fully integrated GbE Media Access
Control (MAC) and Physical Layer (PHY) ports.
The Intel
®
82575EB controller provides a standard IEEE 802.3 Ethernet interface for
1000BASE-T, 100BASE-TX, and 10BASE-T applications (802.3, 802.3u, and 802.3ab) and is
capable of transmitting and receiving data at rates of 1000 Mbps, 100 Mbps, or 10 Mbps.
Each network interface controller (NIC) port provides two LEDs:
 Link / activity LED (at the left of the connector): Indicates network connection when on,
and transmit / receive activity when blinking.
 The speed LED (at the right of the connector) indicates 1000-Mbps operation when
amber; 100-Mbps operation when green; and 10-Mbps when off. The following table
provides an overview of the LEDs.
