The cabinet must meet minimum size requirements. Airow 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 S3048–ON in a common bond network (CBN).
Connect the grounding cables as described in Install the S3048–ON.
Fans and airow
The S3048–ON fans support two airow options—normal and reverse.
Fan combinations
Installation of the fans is done as part of the factory install based on stock keeping units (SKU) type. The S3048-ON has SKUs that
support the following congurations:
• AC PSU with fan airow from the I/O to the PSU
• AC PSU with fan airow from the PSU to the I/O
Be sure to order the fans suitable to support your site’s ventilation. Use a single type of airow fan in your switch. Do not mix reverse and
normal airows in a single S3048–ON chassis.
For proper ventilation, position the S3048-ON 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 S3048-ON switch near each other, to permit proper airow, position the two chassis at least 5
inches (12.7 cm) apart. The fan speed increases when the internal temperature reaches 161.6°F (72°C) and decreases to normal speed
when the temperature falls to 136.4°F (58°C). The S3048-ON never intentionally turns o the fans.
Power
To connect the chassis to the applicable power source, use the appropriate power cord with the S3048–ON. An AC power cord is included
with the switch.
When installing AC switches, follow the requirements of the National Electrical Code, ANSI/NFPA 70 where applicable.
The switch is powered-up as soon as the power cord is connected between the switch and the power source.
CAUTION
: Always disconnect the power cable before you service the power supply slots.
CAUTION: Use the power supply cord as the main disconnect device on the AC switch. Ensure that the socket-outlet is located/
installed near the equipment and is easily accessible.
Storing components
If you do not install your S3048–ON and components immediately, properly store the switch and all optional components by following these
guidelines:
• Storage location temperature must remain constant. The storage range is from -40° to 158°F (-40°C to 70°C).
