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.
