5-3. Connecting 100Base-TX Fast Ethernet Network
The system board provides an RJ-45 port for connection to 100Base-TX Fast
Ethernet or 10Base-T Ethernet Network with a single connection over unshielded
twisted-pair (UTP). The adapter automatically operates at 10Mbps or 100Mbps
when the appropriate 10/100Base hub is connected.
To connect the adapter to 100Base-TX Fast Ethernet Network, you need a
twisted-pair Category 5 cable with RJ-45 modular jacks at both ends. This cable
can have a maximum length of 300 feet (100 meters).
5-4. Connecting 10Base-T Ethernet Network
To connect the adapter to a 10Base-T Ethernet Network, you need a twisted-pair
Category 3, 4 or 5 cables with RJ-45 modular jacks at both ends. This cable can
have a maximum length of 300 feet (100 meters).
5-5. 10MBase/100MBase Installation Notice
• 100Mbps network must be shielded twisted-pair (STP) or Category 5 unshielded
twisted-pair cable. Do not use a Category 3 or 4 cable for 100Mbps-network operation,
it could cause data loss. Category 3 or 4 cable is good for 10Mbps network only.
• Category 5 cable is also good for 10Mbps operation. Use UTP Category 5 cable for
the versatility to operate the network at either 100Mbps or 10Mbps speed without
changing cable.
• Two pairs of wiring are required.
• Depending on building codes, different insulation materials may be required.
Plenum-rated or TEFLON-coated wiring maybe required in some areas where
fireproofing is required.
• The wire gauge should be between 18 and 26 AWG (Most telephone installations use
24-gauge wiring).
• UTP cable should meet the following requirements:
1. Solid copper
2. Nominal capacitance: less than 16pF/ft
3. Nominal impedance: 100 ohms
4. Nominal attenuation: less than 11.5db

Automatic Selection of the Media Type
While the driver installs, it automatically detects the media type based on the type of
cable connected. Once you change the cable type, you must reinstall the driver to
execute auto-detect again.
If the driver cannot detect which cable is connected or whether a cable is
connected, look at cabling network driver (Ex. Modify net.cfg file
parameters—force line speed=10 or 100).
10/100 Auto – Negotiation (N-Way)
Depending on the hub or connected device, the LAN adapter can automatically run
at the appropriate speed, by using N-way, a feature that complies with the
IEEE802.3 standard. It also works with any of the other IEEE-compliant products.
5-6. Remote BOOT ROM function
This function is available with the BIOS programming for indicated operation
system. The remote boot function allows the computer to boot up over the network,
instead of using the local operating system device. This enables the system to be a
diskless workstation environment.
5-7. LED Indicators
The system board comes with two LED indicators on the edge of the motherboard
that indicates the network system status. If you experience any problems with the
adapter, first make sure the appropriate driver is loaded, the proper cable is
connected to the RJ-45 port and the hub complies with the adapter specification,
such as 10Mbps 10Base-T or 100Mbps 100Bast-TX. Finally, recheck the LEDs.
FUDUP (Full Duplex) Indicator
When indicator is ON, it indicates Full-duplex mode: otherwise, it is OFF. The
adapter supports full duplex at 10 or 100Mbps. If the switch-hub supports the
N-way feature and full duplex, the system will automatically runs in full duplex
mode.
Tx/Rx (Transmit/Receiver) Indicator
This indicator flashes to display that there is network activity – indicating
transmission or reception data from the network.
