connectors, Accton provides an optional SC-ST Converter (Part Number: ST5002).

Twisted-Pair Cable and Pin Assignments

Caution: DO NOT plug a phone jack connector into any RJ-45 port. Use only twisted-pair
cables with RJ-45 connectors that conform with FCC standards.
For 100BASE-TX/10BASE-T connections, a twisted-pair cable must have two pairs
of wires. Each wire pair is identified by two different colors. For example, one wire
might be red and the other, red with white stripes. Also, an RJ-45 connector must be
attached to both ends of the cable.
Caution: Each wire pair must be attached to the RJ-45 connectors in a specific
orientation. (See "Cabling Guidelines" on page 4-1 for an explanation.)
