Stacking Units

PowerConnect 5500 series switches use two HDMI 10G ports for stacking.
To connect the units in the stack:
1 Insert one end of an HDMI cable into the left-hand HDMI port on the
unit at the top of the stack and the other end into the right-hand HDMI
port of the unit immediately below it (this is called crossover).
2 Repeat this process until all units are connected.
3 (Optional) Connect the left-hand HDMI port of the unit at the bottom of
the stack to the right-hand HDMI port of the unit at the top of the stack.
This step provides increased bandwidth and redundancy.
