Page 10 Install the EX4400 in a Rack You can install the EX4400 switch on a desktop or other level surface, in a two-post or four-post rack, or on a wall. We’ll walk you through the steps to install an AC-powered switch in a two-post rack.
Page 11 Ground the EX4400 Switch | 3 Connect the Power Cord and Power On the Switch | 4 To connect the EX4400 switch to AC power, you must do the following: Ground the EX4400 Switch To ground the EX4400 switch, do the following:...
Page 12 2. Place the grounding lug attached to the grounding cable over the protective earthing terminal on the rear panel. 3. Secure the grounding lug to the protective earthing terminal using the 10-32 x .25-in. screws with #10 split-lock washers. 4. Dress the grounding cable. Be sure that the cable doesn’t block access to or touch other device components, and that it doesn’t drape where people could trip over it.

Page 87 The cooling system in an EX4400 switch consists of two fan modules for the chassis and a single built-in fan in each power supply. The airflow direction depends on the fan modules and power supplies installed in the switch. You can order an EX4400 switch that supports front-to-back (air enters through the front panel of the switch) or back-to-front airflow (air enters through the rear panel of the switch).
