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 S5048F-ON switch in a common bond network (CBN).
Connect the grounding cables as described in
.
Fans and airflow
The S5048F-ON 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 S5048F-ON 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 S5048F-ON 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 S5048F-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 S5048F-ON 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 the switch.
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
CAUTION:
Always disconnect the power cable before you service the power supply slots. The switch has multiple power cords.
Before servicing, ensure all power cords are disconnected.
CAUTION:
On an AC switch, use the power supply cord as the main disconnect device. Ensure that the socket-outlet is located
and installed near the equipment and is easily accessible.
NOTE:
Module power is software controlled. You do not see module LEDs when the switch powers up in ONIE.
