The cabinet must meet minimum size requirements. Airflow must be in accordance with the Electronic Industries Alliance (EIA) standard.
Ensure that there is a minimum of 5 inches (12.7 cm) between the intake and exhaust vents and the cabinet wall.
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 EMC recommends you ground your switch. Use the S5200F-ON Series switch in a common bond network (CBN).
Connect the grounding cables as described in
S5200F-ON Series switch installation
.
NOTE:
For an AC-powered switch, although the third conductor of the AC power cord provides a ground path, Dell EMC
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 placed with the other accessories inside the shipping box. The ground lug bracket screws ship attached
to the switch. Before you install the DC switch in the dual-tray, attach the ground lug and bracket to the switch using the
included screws and then attach the DC ground wire to the ground lug. The DC-powered switch ships with the DC ground lug,
bracket, and screws.
Fans and airflow
The S5200F-ON Series switch fans support two airflow options: normal and reverse.
Fan combinations
Fan installation is done as part of the factory install based on stock keeping unit (SKU) type. The S5200F-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
Order the fans suitable to support your site’s ventilation. Use a single type of airflow fan in your switch. Do not mix reverse and normal
airflows in a single S5200F-ON Series switch.
For proper ventilation, position the switch in an equipment rack or cabinet with a minimum of 5 inches (12.7 cm) of clearance around the
exhaust vents. When you install two S5200F-ON switches near each other, to permit proper airflow, position the two switches at least 5
inches (12.7 cm) apart. The fan speed varies based on internal temperature monitoring. The S5200F-ON Series switch never intentionally
turns off the fans.

Power
To connect the switch to the applicable power source, use the appropriate power cord. An AC power cord is included with each PSU.
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 cord between the switch and the power source. For more information, see
