Optic installation
The S4048T-ON system has 48 RJ-45 ports and six quad small form-factor pluggable plus (QSFP+) optical ports.
For a list of supported optics, see the S4048T-ON Specication Sheet at www.dell.com/support/ or contact your Dell EMC Networking
representative.
CAUTION
: ESD damage can occur if the components are mishandled. Always wear an ESD-preventive wrist or heel ground strap
when handling the system and its components.
WARNING: When working with optical bers, follow all the warning labels and always wear eye protection. Never look directly
into the end of a terminated or unterminated ber 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 40 GbE optics with the tabs facing up.
NOTE: When you cable the ports, do not block the airow from the small ventilation holes over and below the
ports.
