  • Page 7: The S4820T Switch

    The S4820T system is a top-of-rack (ToR) switch/router product for copper connections to 10Gbps servers and 40Gbps optical uplinks to the 40Gbps switching fabric in the core. The S4820T has 48 ports of RJ-45 10GBase-T and four ports of 40Gbps with features and functions similar to the S4810 product.

  • Page 8: Prerequisites

    By providing increased 40GbE bandwidth for device interconnection in a shared network storage environment (with the possibility of splitting 40GbE quad small form-factor pluggable plus (QSFP+) uplinks into four 10GbE SFP+ or RJ-45 connections), the S4820T switch is perfectly positioned to help transition a data center with multiple speed requirements.

  • Page 14: Rack Mounting

    Reversed — airflow is from the power supply to the I/O panel For proper ventilation, position the S4820T in an equipment rack (or cabinet) with a minimum of five inches (12.7cm) of clearance around the exhaust vents. When you install two S4820T systems near each other, position the two chassis at least five inches (12.7cm) apart to permit proper airflow.

  • Page 15: Storing Components

    WARNING: Electrostatic discharge (ESD) damage can occur when components are mishandled. Always wear an ESD-preventive wrist or heel ground strap when handling the S4820T and its accessories. After you remove the original packaging, place the S4820T and its components on an antistatic surface.

  • Page 17: Install The Hardware

    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.

  • Page 18: Install The Chassis

    To install the S4820T system, Dell Networking recommends completing the installation procedures in the order presented in this document.

  • Page 19: Install The Dell Readyrails System

    NOTE: The illustrations in this document are not intended to represent a specific switch. Install the Dell ReadyRails System Dell Networking provides the ReadyRails rack mounting system so you can easily configure a rack to install the S4820T switch. You can install the ReadyRails system using the 1U tool-less method or one of three possible 1U tooled methods (two-post flush mount, two-post center mount, or four-post threaded).

  • Page 20: Installing Readyrails - Tool-Less Method

    Installing ReadyRails — Tool-less Method Use this installation method for four-post square hole or unthreaded round hole. With the ReadyRails flange ears facing outward, place one rail between the left and right vertical posts. Align and seat the rear flange rail pegs in the rear vertical post flange. In the following figure, item 3 and its extraction shows how the pegs appear in both the square and unthreaded round holes.
