NOTE: Both rows of QSFP+ ports require that you install the 40 GbE
optics with the tabs facing up.
NOTE: When you cable the ports, be sure not to interfere with the
airflow from the small vent holes above and below the ports.
Supply Power and Power Up the System
Dell Networking recommends reinspecting your system prior to powering up.
Connecting the power cable powers up the switch.
Verify that:
•
The equipment is properly secured to the rack.
•
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 system.
•
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: ESD damage can occur if the components are mishandled.
Always wear an ESD-preventive wrist or heel ground strap when
handling the system and its components.
Supply power to the system:
•
Plug in the appropriate cord (AC 3 prong or DC wiring) from the switch
PSU to the external power source (either AC wall outlet or DC rack bus
bar). Make sure that the power cord is secure. When the cable is
connected between the system and the power source, the switch is
powered up; there is no on/off switch.
•
When the system powers up, the fans come on at high speed. The fan
speed slows as the system boots up. The power status LED blinks until the
boot-up sequence is complete. When the boot up is complete, the power
status LED is steadily lit.
After Installing the S4048T-ON
After you have securely installed and powered on the S4048T-ON, to
configure your system, see your ONIE-compatible operating system
documentation.
