Install the Hardware
This information describes installation of the S4048T-Open Networking (ON)
system. Dell Networking recommends completing the installation procedures
in the order presented here.
Operation and Safety Considerations
Before installing the switch, review these operation and safety guidelines.
Review these guidelines for switch installation:
•
You have enough clearance to the front of the switch so you can read the
light emitting diodes (LEDs).
•
The AC power cord reaches from the power outlet to the power supply
unit (PSU) side connector.
•
The switch is rack-mounted before you power it up.
•
Cabling is away from sources of electrical noise, such as radios, power
lines, and fluorescent lighting. Ensure that the cabling is safely away from
other devices that might damage the cables. If needed, allow one rack unit
(RU) space between devices to provide room for cabling.
•
Airflow around the switch and through the vents is unrestricted.
•
Temperature around the unit does not exceed 113°F (45°C). If the switch is
in a closed or multi-rack assembly, the temperature might be higher than
normal room temperature.
•
Humidity around the switch does not exceed 95 percent.
•
Altitude at the installation site is below 10,000 feet.
•
The switch is installed in an environment as free as possible from dust and
foreign conductive material (such as metal flakes from construction
activities). Cooling mechanisms, such as fans and blowers in the switch,
can draw dust and other particles causing contaminant buildup inside the
chassis, which can result in system malfunction.
Review these guidelines for rack mounting:
•
Rack mounting — You may either place the switch on a rack shelf or
mount the switch directly into a 19" wide, EIA-310-E- compliant rack.
•
Rack loading — Overloading or uneven loading of racks may result in shelf
or rack failure, causing damage to the equipment and possible personal
injury. Stabilize racks in a permanent location before loading begins.
Mount the components starting at the bottom of the rack, then work to
the top. Do not exceed your rack load rating.
