Install the Hardware
Before installing the switch, verify that you meet these guidelines:
•
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 Utility panel 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 multirack
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.
Install the Chassis
To install the S4048–Open Networking (ON) system, Dell Networking recommends completing the
installation procedures in the order presented here.
NOTE: Always handle the system and its components with care. Avoid dropping the S4048–ON
chassis or its field replaceable units.
NOTE: For proper ventilation, position the S4048–ON chassis in an equipment rack (or cabinet) with
a minimum of 5 inches (12.7 cm) of clearance around exhaust vents. The acceptable ambient
temperature ranges are listed in the
Parameters.
CAUTION: Always wear an electrostatic discharge (ESD)-preventive wrist or heel ground strap
when handling the S4048–ON and its components. As with all electrical devices of this type, take
all necessary safety precautions to prevent injury when installing this system. ESD damage can
occur if components are mishandled.
CAUTION: The S4048–ON contains two power cords. Disconnect both power cords before
servicing.
CAUTION: Only trained and qualified personnel should install this equipment. Read this guide
before installing and powering up the S4048–ON.
