12 Intel Server Board SE7500WV2 Product Guide
Network Controller
✏ NOTE
To ensure EMC product regulation compliance, the system must be used
with a shielded LAN cable.
The server board uses the Intel® 82546EB Fast Ethernet† Controller and supports two
10Base-T/1000Base-TX network subsystems.
The 82546EB controller supports the following features:
• 32-bit PCI 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, 100 Mbps, and 1000 Mbps operation
• Low power +3.3 V device
On the SE7500WV2, NIC 1 can be used as both a network interface and server management
interface.

NIC Connector and Status LEDs

The 82546 controller drives LEDs on the network interface connector that indicate link/activity on
the LAN and speed of operation. The green LED indicates network connection when on and
TX/RX activity when blinking. The speed LED indicates 1000 Mbps when amber, 100 Mbps when
green, and 10 Mbps when off.
Keyboard and Mouse
The keyboard/mouse controller is PS/2-compatible. If specified through the System Setup Utility
(SSU), the server may be locked automatically if there is no keyboard or mouse activity for a
predefined length of time. Once the inactivity (lockout) timer has expired, the keyboard and mouse
do not respond until the previously stored password is entered. A Y-cable can be used if both a
PS/2 mouse and keyboard are required at the same time.
RJ-45 Serial Port
The rear RJ-45 serial port is a fully functional serial port that supports any standard serial device
and provides support for serial concentrators. For server applications that use a serial concentrator
to access the server management features of the baseboard, a standard 8-pin CAT-5 cable from the
serial concentrator is plugged directly into the rear RJ-45 serial port. The 8 pins of the RJ-45
connector can be configured to match either of two pin-out standards used by serial port devices.
To accommodate either standard, the J5A2 jumper block located directly behind the rear RJ-45
serial port must be jumpered appropriately according to the desired standard.
