Optics Removal; Switch Power-Up; Power Up Sequence; After Switch Installation - Dell EMC S4112F-ON Installation Manual

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 firmly 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.

Switch power-up

Supply power to the S4112-ON Series (S4112F-ON and S4112T-ON) switch after 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 specified for the S4112–
ON Series, see Specifications.
• There is sufficient airflow around the unit.
• The input circuits are correctly sized for the loads and that you use sufficient overcurrent protection devices.
• All protective covers are in place.
• Blank panels are installed if you do not install optional modules.
NOTE: A US AC power cable is included for powering up an AC power supply. You must order all other power cables separately.
NOTE: ESD damage can occur if components are mishandled. Always wear an ESD-preventive wrist or heel ground strap when
handling the S4112–ON Series switch and its components.

Power up sequence

When the switch powers up, the fans immediately come on at high speed. The fan speed slows as the switch continues to boot up.
