Figure 3-11. Up to 8 Switches in a Switch Stack
The stacking ports are marked IN and OUT. The IEEE 1394
compliant cable must be connected from an IN port on one
switch to an OUT port on the next switch in the stack. The last
two switches (at the top and bottom of the stack) must also be
connected from the IN port on one switch to the OUT port on
the other switch. In this way, a loop is made such that all of
the switches in the switch stack have the IN stacking port
connected to another switch's OUT stacking port.
The Stacking Module's LED indicators are described below.
