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 grounding your switch. Use the S4200-ON Series switch in a CBN.
Fans and airflow
Fan installation is done as part of the factory install based on stock keeping unit (SKU) type. The S4200-ON Series has SKUs
that support the following configurations:
●
AC PSU with fan airflow from the I/O to the PSU—normal
●
AC PSU with fan airflow from the PSU to the I/O—reverse
●
DC fan unit with airflow from the I/O to the PSU—normal
●
DC fan unit with fan airflow from the PSU to the I/O—reverse
Be sure to 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 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. The fan speed varies based on internal temperature monitoring. The switch never intentionally turns
off the fans.
Power
To connect the switch to the applicable power source, use the appropriate power cable. An AC power cable 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 the power cable is connected between the switch and the power source.
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 the AC switch, use the power supply cable as the main disconnect device. Ensure that the
socket-outlet is located/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.
Storing components
If you do not install your S4200-ON Series switch and components immediately, properly store the switch and all optional
components following these guidelines:
●
Storage location temperature must remain constant. The storage range is from -40°C to 70°C (-40°F to 158°F).
●
Store on a dry surface or floor, away from direct sunlight, heat, and air conditioning ducts.
●
Store in a dust-free environment.
NOTE:
ESD damage can occur when components are mishandled. Always wear an ESD-preventive wrist or heel ground
strap when handling the switch and its accessories. After you remove the original packaging, place the S4200-ON Series
switch and its components on an anti-static surface.
