Switch Power-Up; Power Up Sequence; After System Installation - Dell EMC S4112-ON Series Setup Manual

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.
Reinspect your switch before power 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 switch, 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 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.
