Install the Hardware
Always handle the S4820T and its components with care. Avoid dropping the system or its field
replaceable units (FRUs). Dell Networking recommends completing the installation procedures in the
order presented in this document.
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/DC 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 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 104°F (40°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 85 percent.
• Altitude at the installation site is below 6600 feet.
• You install the switch 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.
Unpacking the Switch
The S4820T and its accessories are shipped in multiple boxes.
Before unpacking the switch, inspect the container and immediately report any evidence of damage.
Verify that you have received your ordered items. For example, if you order one S4820T switch, the
following items are included.
WARNING: If any item is missing or damaged, contact your Dell Networking representative or
reseller for instructions.
WARNING: Electrostatic discharge (ESD) damage can occur if components are mishandled.
Always wear an ESD-preventive wrist or heel ground strap when handling the S4820T and its
components.
