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 S5148F-ON switch after it is mounted in a rack or cabinet.
Dell EMC recommends reinspecting your switch before powering it up. Verify the following:
● Optional: The equipment is properly secured to the rack and properly grounded.
● Optional: The equipment rack is properly mounted and grounded.
● The ambient temperature around the unit, which may be higher than the room temperature, is within the limits specified for
the S5148F-ON switch. For more information, 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.
CAUTION:
Do not power up the switch if you did not install a fan module.
NOTE:
A US AC or DC power cable is included for powering up an AC or DC power supply. You must order all other power
cables separately.
