Installing the System on a Table Top or in a 
Free-Standing Stack

To install the Switch 3900 system on a table top or in 
a free-standing stack, follow these instructions:

1

See Appendix B for site requirements.

2

Turn the system on its side.

3

Remove the protective covering from the rubber feet.

4

Place one rubber foot in each marked area at the four 
corners of the unit.

5

Turn the system onto its feet.

6

Verify that the air intake vents and fan exhaust vents 
at the sides of the system are not blocked.

To install the system into a free-standing stack, place 
the system on top of another. Be sure that the rubber 
feet of the upper unit fit securely in the recesses in 
the top of the lower unit. See Figure 2-1.

CAUTION: 

Stack no more than eight SuperStack II 

systems in a single free-standing stack.

You are now ready to cable your system. For 
instructions, see Chapter 3.
