The stacking transceiver provides two 1 Gbps ports via USB Type-A connectors. The
upper port is a transmit port and the lower one is a receive port. The transceiver allows
up to eight switches to be linked together using stacking cables (one stacking cable is
included with each optional stacking transceiver). The push button on the switch’s front
panel enables one switch in the stack to be selected as the master. (See “Stack Master
Button” on page 1-5.)
