Ground Cable; Desktop - Dell PowerSwitch N3200-ON Series Installation Manual

● Power considerations—Connect only to the power source specified on the unit. When you install multiple electrical
components in a rack, ensure that the total component power ratings do not exceed the circuit capabilities. Overloaded
power sources and extension cables present fire and shock hazards.
● Elevated ambient temperature—If installed in a closed rack assembly, the operating temperature of the rack environment
may be greater than the room ambient temperature. Use care not to exceed the 45°C (113°F) maximum ambient
temperature of the switch.
● Reduced airflow—Install the equipment in the rack so that the amount of airflow that is required for safe operation of the
equipment is not compromised.
● Reliable earthing—Maintain reliable earthing of rack-mounted equipment. Pay particular attention to the supply connections
other than the direct connections to the branch circuit, for example, use of power strips.
● Do not mount the equipment with the backpanel facing downward.

Ground cable

To attach a ground cable to the switch, use the included M4 screws.
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.
The ground cable is not included.
The ground lug ships with the optionally ordered DC version PSUs. The AC-no-OS version of the N3248PXE-ON/E3248PXE-ON
switch, which you must special order, also ships with the ground lug.
CAUTION: Grounding conductors must be made of copper. Do not use aluminum conductors.
NOTE: Coat the one-hole lug with an antioxidant compound before crimping. Also, bring any unplated mating surfaces to a
shiny finish and coat with an antioxidant before mating. Plated mating surfaces must be clean and free from contamination.
NOTE: The rack installation ears are not suitable for grounding.
To connect the ground cable to the switch:
1. Cut your user-supplied ground cable to the wanted length.
The cable length must facilitate proper operation of the fault interrupt circuits. Use the shortest cable route allowable.
2. Crimp the ground cable inside the ground lug.
3. Attach the other end of the ground cable to a suitable ground point such as the rack or cabinet.
The rack installation ears are not a suitable grounding point.

Desktop

One mounting option is to place the N3200-ON/E3200-ON Series switch on a desktop.
The mounting supplies for this installation ship with the switch.
1. Locate the four rubber feet shipped with the switch.
2. Remove the paper backing on the bottom of one of the rubber feet.
3. Adhere the rubber foot to one of the four round position marks on the underside of the switch.
4. Repeat the process for the remaining three rubber feet.
