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 S4100–ON Series (S4128F-ON, S4148F-ON, S4148FE-ON, S4128T-ON, S4148T-ON, and S4148U-ON)
switch after you mount it in a rack or cabinet.
Dell Technologies recommends reinspecting your switch before powering up. Verify the following:
● The equipment is properly secured to the rack. Dell Technologies 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 S4100–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.
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 switch and its components.
CAUTION:
Do not power up the switch if you did not install a fan module.
NOTE:
A US AC power cable is included for powering up an AC power supply. You must order all other power cables
separately.
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.
