JPSU-150-DC-AFO 150W DC power supply
Front-to-back airflow
Power cord ordered separately
Front-to-back—that is, air intake to cool the chassis is through the vents on the front panel of the chassis and hot air exhausts through the vents on the rear panel of the chassis.
The DC 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.
You can install up to two DC power supplies in an EX3400 switch. Power supplies are installed in the power supply slots labeled PSU 0 and PSU 1 in the rear panel of the chassis.
To install a DC power supply in the switch:
1. Ensure that the fan modules installed in the switch have the AIR OUT label on them.
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.
