Front Panel Video Memory
When the SE7501WV2 server board is integrated into either a SR2300 or SR1300 chassis, the
SE7501WV2 supports video through the front panel or the rear I/O panel. This is accomplished
by routing video to two connectors. The rear video is provided through the standard DB15 video
connector located in the rear I/O panel. Video is routed to the front panel through the high-
density 100-pin connector.

Video is routed to the rear video connector by default. When a monitor is plugged into the front
panel video connector, video is routed to the front panel connector and the rear connector is
disabled. This can be done by “hot plugging” the video connector while the system is still
running.

4.10 Network Interface Controller (NIC)
The SE7501WV2 server board supports a dual-channel gigabit network interface controller
based on the Intel
based on the Intel
®
82546EB. The 82546EB is a highly integrated PCI LAN controller in a 21
mm
2
PBGA package. The controller supports 10/100/1000 operation on both channels as well
as supports alert-on-LAN functionality. The SE7501WV2 server board supports independent
disabling of the two NIC controllers using the BIOS Setup menu.

•
32-bit PCI/CarBus master interface
•
Integrated IEEE 802.3 10Base-T, 100Base-TX and 1000Base-TX compatible PHY
•
IEEE 820.3u auto-negotiation support
•
Full duplex support at 10 Mbps, 100Mbps and 1000 Mbps operation
•
Integrated UNDI ROM support
•
MDI/MDI-X and HWI support
•
Low power +3.3 V device

NIC Connector and Status LEDs
The 82546EB drives two LEDs located on each network interface connector. The link/activity
LED (to the left of the connector) indicates network connection when on, and Transmit/Receive
activity when blinking. The speed LED (to the right of the connector) indicates 1000-Mbps
operations when amber, 100-Mbps operations when green, and 10-Mbps when off.

4.11 Interrupt Routing
The SE7501WV2 server board interrupt architecture accommodates both PC-compatible PIC
mode and APIC mode interrupts through use of the integrated APICs in the ICH3-S and the
P64H2.
