AC power supply replacement
CAUTION: Disconnect the power cord before removing the power supplies. Also, disconnect all power cords
before servicing.
NOTE: The PSU slides into the slot smoothly. Do not force a PSU into a slot as this action may damage the PSU or the
S3048–ON chassis.
NOTE: If a PSU fails, you must replace the entire unit. There are no field serviceable components in the PSU.
NOTE: If you use a single PSU, install a blank plate in the other PSU slot. If you are only using one power supply, Dell EMC
recommends installing the power supply in the first slot (PSU1) and installing a blank plate in the second slot (PSU2).
1. Disconnect the power cable from the PSU.
2. Use the grab handle to slide the PSU out of the power supply bay.
3. Use the grab handle on the replacement PSU to slide it into the power supply bay.
4. Attach the power cord to the replacement PSU.
NOTE: The switch powers up when you connect the cables between the power supply and the power source.
