Supply Power And Power Up The System - Dell S4820T Installation Manual

Supply Power and Power Up the System

Supply power to the S4820T after the chassis is mounted in a rack or cabinet.
Dell Networking recommends re-inspecting your system prior to powering up. 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 S4820T.
• 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.
NOTE: A country/region-specific AC power cable is included in the shipping container for powering
up an AC power supply. You must order all other power cables separately.
CAUTION: ESD damage can occur if the components are mishandled. Always wear an ESD-
preventive wrist or heel ground strap when handling the S4820T and its components.
CAUTION: Ensure that the PSU is installed correctly. The AC power connector must be on the left
side of the PSU and the status LED at the top of the PSU.
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.
