Dell EMC recommends reinspecting your switch before starting 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 that are specified for
the Z9264F-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 start 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
