Network Interface Controller (Nic); Optional Scsi Card - Intel SE7500CW2 Technical Product Specification

Included PCI Devices
4.2.1.2 Video Memory Interface
The memory controller subsystem of the ATI Rage XL arbitrates requests from direct memory
interface, the VGA graphics controller, the drawing coprocessor, the display controller, the video
scalar, and hardware cursor. Requests are serviced in a manner that ensures display integrity
and maximum CPU/coprocessor drawing performance.
The Intel Server Board SE7500CW2 supports an 8MB (512Kx32bitx4 Banks) SDRAM device for
video memory.

Network Interface Controller (NIC)

The SE7500CW2 server board supports two 10Base-T/100Base-TX Network Interface
Controllers (NICs) based on the Intel 82550PM NIC. The 82550PM is a highly integrated PCI LAN
controller in a thin BGA 15mm package. The controller's baseline functionality is equivalent to
that of the Intel 82559, with the addition of Alert-on-LAN functionality. The SE7500CW2 server
board supports independent disabling of the two NIC controllers using the BIOS Setup menu.
The 82550PM supports the following features:
•
Glueless 32-bit PCI, CardBus master interface (Direct Drive of Bus), compatible with PCI
local Bus Specification, Revision 2.2.
•
Integrated IEEE 802.3 10Base-T and 100Base-TX compatible PHY.
•
IEEE 820.3u auto-negotiation support.
•
Full duplex support at both 10 Mbps and 100 Mbps operation.
•
Integrated UNDI ROM support.
•
MDI/MDI-X and HWI support.
•
Low power +3.3 V device.
4.3.1.1 NIC Connector and Status LEDs
The 82550PM drive two LEDs located on each network interface connector. The amber LED
indicates network connection when on, and transmit/receive activity when blinking. The yellow
LED indicates 100-Mbps operating mode when lit, and 10-Mbps when off.
4.4

Optional SCSI Card

Certain versions of the SE7500CW2 server board include an add-in Ultra-160 SCSI card. This
card has the following specifications:
•
Ultra 160 single channel based on the LSI 53C1000 SCSI controller
•
PCI 2.2 compliant
•
PCI 64-bit/66MHz operation
•
Universal PCI card edge connector
•
Low profile form factor, shipping with full-size PCI bracket attached and low profile
bracket in packaging
•
Internal and external connectors (internal standard 68-pin, external VHDI interface)
•
Termination: universal (LVD/SE) termination, automatic cable detection, software disable
