MAXDATA PLATINUM Server Board
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
®
Fast Ethernet Controller, 82546EB, 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 MAXDATA PLATINUM Server Board, NIC 1 can be used as both a network interface
and server management interface.
NIC Connector and Status LEDs
The E82546 controller drives LEDs on the network interface connector that indicate
link/activity on the LAN
and speed of operation. The green status 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.

NOTE
By default, the RJ-45 serial port is configured to support a DSR signal.
For serial devices that require a DSR signal (default), the J5A2 jumper must be configured
in position 3-4 (Figure 3, B).
For serial devices that require a DCD signal, the jumper must be in position 1-2 (Figure 3, A).
