Back-to-front airflow

Power cord ordered separately

The AC power supplies in EX3400 switches are hot-insertable and hot-removable field-replaceable units (FRUs): You can install them without powering off the switch or disrupting the switching function. The switch is shipped with one power supply installed.

A detachable AC power cord is supplied with the AC power supplies. The coupler is type C13 as described by International Electrotechnical Commission (IEC) standard 60320.




To install an AC power supply in the switch:

1. Ensure that you have the correct power supply. The direction of the airflow in the power supply must match the direction of the airflow in the installed fan module.

2. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.

3. If the power supply slot has a cover panel on it, loosen the captive screws on the cover panel by using your fingers or the screwdriver. Hold the captive screw and gently pull it outward to remove the cover panel. Save the cover panel for later use.

4. Taking care not to touch power supply pins, leads, or solder connections, remove the power supply from the bag.

5. Using both hands, place the power supply in the power supply slot on the rear panel of the switch and slide it in until it is fully seated and the ejector lever fits into place.

EX3400-FAN-AFI spare fan

Back-to-front airflow

The cooling system in an EX3400 switch consists of two fans along the rear of the chassis and a fan each in the power supplies.

In switch models with back-to-front airflow, the air intake is located on the rear of the chassis. Cool air is pulled into the chassis and pushed toward the front of the chassis. Hot air exhausts from the front of the chassis.
