Rack mounting

When you prepare your equipment rack, ensure that the rack is grounded.
Ground the equipment rack to the same ground point the power service in your area uses. The ground path must be permanent.

Switch ground

Dell Technologies recommends you ground your switch. Use the N3200-ON/E3200-ON Series switch in a common bond
network (CBN).
Connect the grounding cables as described in
NOTE: For an AC-powered switch, although the third conductor of the AC power cable provides a ground path, Dell
Technologies recommends grounding your switch with a dedicated ground wire.
NOTE: For a DC-powered switch, the only way to safely ground your switch is to attach a dedicated ground wire. The
ground lug kit ships in a plastic bag that is placed with the other accessories inside the shipping box. To ground your switch,
first attach the ground lug to the switch using the screws. Then attach the DC ground wire to the ground lug.

Fans and airflow

The N3200-ON/E3200-ON Series include three hot-swappable fan units, except the N3208PX-ON, which has one fan.
Fan combinations
Fan installation is completed as part of the factory install based on stock keeping unit (SKU) type. The N3200-ON/E3200-ON
Series switch has SKUs that support the following configurations:
● AC or DC PSU with fan airflow from the I/O to the PSU—the red indicator is the normal airflow direction.
● AC or DC PSU with fan airflow from the PSU to the I/O—the blue indicator is the reverse airflow direction.
NOTE: All N3200-ON/E3200-ON Series switches except N3208PX-ON support normal airflow.
NOTE: Only N3224T-ON, N3248TE-ON, and N3248X-ON AC switches support reverse airflow.
Order the fans suitable to support the ventilation at your site. Use a single type of airflow fan in your switch. Do not mix reverse
and normal airflows in a single N3200-ON/E3200-ON Series switch.
For proper ventilation, position the switch in an equipment rack or cabinet with a minimum of 12.7 cm (5 inches) of clearance
around the exhaust vents. When you install two N3200-ON/E3200-ON Series switches near each other, to permit proper
airflow, position the two switches at least 12.7 cm (5 inches) apart. The fan speed varies based on internal temperature
monitoring. The N3200-ON/E3200-ON Series switch never intentionally turns off the fans.
For more information, see Fans.

Power

To connect the switch to the applicable power source, use the appropriate power cable. An AC power cable is included with
each PSU. If you optionally order DC PSUs, they ship with a DC power cable.
When installing AC or DC switches, follow the requirements of the National Electrical Code, ANSI/NFPA 70, where applicable.
The switch is powered-up when you connect the power cable between the switch and the power source. For more information,
see Power supplies.
WARNING: This equipment must be earthed. Connect the power plug to a properly wired earth ground socket
outlet.
CAUTION: Always disconnect the power cable before you service the power slots. The switch has multiple power
cables. Before servicing, ensure that all power cables are disconnected.
