Removing a DC power supply

WARNING: For equipment using –(48–60) V DC power supplies, a qualified electrician must perform all connections to DC power and to safety grounds. Do not attempt connecting to DC power or installing grounds yourself .All electrical wiring must comply with applicable local or national codes and practices. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow all safety instructions that came with the product.

CAUTION: The system requires one power supply for normal operation. On power-redundant systems, remove and replace one power supply at a time when a system is turned on.

NOTE: You must unlatch and lift the optional cable management arm if it interferes with power supply removal. For information about the cable management arm, see the system’s rack documentation.

1.Turn off the power switches on the power supply module.

2.Remove the strap that secures the wires to the power supply module handle.

3.Disconnect the power wires from the power source and the connector from the power supply module you intend to remove.

4.Disconnect the safety ground wire.

5.Press the release latch and slide the power supply module out of the chassis.

CAUTION: The power supply module is heavy; support it with both hands.
