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 be 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 fire
proofing 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
