CAUTION: ESD damage can occur if components are mishandled. Always wear an ESD-preventive wrist or heel ground strap
when handling the S4100-ON Series and its components.
WARNING: When working with optical bers, follow all 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
: When you cable the ports, be sure not to interfere with the airow from the small vent holes above and below
the ports.
Optics removal
Remove an optic by pushing the tab on the optic and sliding the optic from the port.
When removing optics with direct attach cables (DACs) from the port, pull the release tab rmly and steadily. Before pulling the release tab,
you may need to gently push the optic into the port to ensure that it is seated properly. Do not jerk or tug repeatedly on the tab.

you mount it in a rack or cabinet.
Dell EMC recommends reinspecting your switch before powering up. Verify the following:
• The equipment is properly secured to the rack. Dell EMC recommends properly grounding the switch.
• The ambient temperature around the unit, which may be higher than the room temperature, is within the limits specied for the S4100–
ON Series, see Specications.
• There is sucient airow around the unit.
• The input circuits are correctly sized for the loads and that you use sucient overcurrent protection devices.
• All protective covers are in place.
