Connecting Repeaters via Repeater Expansion Ports
NOTE:
When you add a repeater to a stack, connect the cable to the repeater you
add before you connect it to the repeater in the existing stack. For example, if you
add a repeater to the top of a stack, connect the cable to the IN port of the added
repeater. Then connect the other end of the cable to the OUT port of the existing
repeater in the stack. Do not leave cables connected at only one end. Doing so
reduces performance. The pin-outs of the IN and OUT ports are shown below.
