S4048-ON Installation Guide January 2019


SFP+ and QSFP+ optic installation

The S4048–ON has six quad small form-factor pluggable plus (QSFP+) optical ports.

For a list of supported optics, refer to the S4048–ON data sheet at www.dell.com/support or contact your Dell EMC sales representative.
  • CAUTION: ESD damage can occur if the components are mishandled. Always wear an ESD-preventive wrist or heel ground strap when handling the S4048–ON and its components.
  • WARNING: When working with optical fibers, follow all the warning labels and always wear eye protection. Never look directly into the end of a terminated or unterminated fiber or connector as it may cause eye damage.
  1. Position the optic so it is in the correct position. The optic has a key that prevents it from being inserted incorrectly.
  2. Insert the optic into the port until it gently snaps into place.
    • NOTE: Both rows of QSFP+ ports require that you install the 40GbE optics with the tabs facing up.
    • NOTE: When you cable the ports, be sure not to interfere with the airflow from the small vent holes above and below the ports.
