Figure 2-1. Default air flow direction of the Series 6600 Switches is from power to 
ports.
The direction of air flow can be reversed from the default direction shown in 
figure 2-1 by reversing the direction of the fans. See step 3 below, Reversing 
the air flow.
Installation Procedures
Summary
1. Prepare the installation site (page 2-5). Ensure the physical environ-
ment is properly prepared, including having the correct network cabling 
ready to connect to the switch and having an appropriate location for the 
switch. See page 2-3 for some installation precautions.
2. Verify the switch passes self test (page 2-5). Plug the switch into a 
power source and observe that the LEDs on the switch’s front panel 
indicate correct switch operation. When self test is complete, unplug the 
switch.
3. (Optional) Reversing the air flow (page 2-8) The direction of air flow 
can be reversed from the default direction by reversing the fans. 
4. Mount the switch (page 2-10). The Switch can be mounted in a 19-inch 
telco rack, or in an equipment cabinet.
