A restricted access area is one in which service personnel can only gain access using a special tool, lock, key or other means of security and access is controlled by the authority responsible for the location.

  • Page 13: Rack Mounting

    Storing components If you do not install your S4048–ON and components immediately, Dell Technologies recommends properly storing the switch and all optional components by following these guidelines. ● Storage location temperature must remain constant ranging from -40° to 158°F (from -40°C to 70°C).
  • Page 14 NOTE: ESD damage can occur when components are mishandled. Always wear an ESD-preventive wrist or heel ground strap when handling the S4048–ON and its accessories. After you remove the original packaging, place the S4048–ON and its components on an anti-static surface. Site preparations...

  • Page 15: Chapter 4: Nebs Compliance

    NEBS compliance For your switch to be network equipment building system (NEBS) compliant, you must follow the instructions that are detailed in this chapter. To be NEBS-compliant, orient your switch in the rack so that the air inlet is from the front aisle, and the air exhaust is to the back aisle.

  • Page 16: Chapter 5: S4048-On Installation

    S4048–ON installation To install the S4048–ON switch, Dell Technologies recommends completing the installation procedures in the order that is in this chapter. Always handle the S4048–ON and its components with care. Avoid dropping the switch or its field replaceable units (FRUs).

    Two-post flush-mount configuration CAUTION: Your switch is not NEBS Earthquake Z4-compliant if you use this installation method. 1. For this configuration, remove the latch castings from the front side of each ReadyRails assembly, item 1. To remove the two screws from each front flange ear on the switch side of the rail and remove each casting, use a Torx screwdriver.
