If the Switch units are free-standing, up to eight units can be placed one 
on top of the other. If you are mixing a variety of SuperStack

 units, the 

smaller units must be positioned at the top.

If you are placing Switch units one on top of the other, you must use the 
self-adhesive rubber feet supplied. Apply the feet to the underside of 
each Switch, sticking one in the marked area at each corner. Place the 
Switch units on top of each other, ensuring that the feet of the upper unit 
sit fully on the lower unit.

The following sections describe how to get your Switch 5500

1 Plug the power cord into the power socket at the rear of the Switch.

2 Plug the other end of the power cord into your power outlet.

which takes approximately one minute.

the LEDs light. The PWR LED will flash green during the POST.

When the POST has completed, check the PWR LED to make sure that 
your Switch is operating correctly.
