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 only one power supply at a time in a system that is powered on.

NOTE: You may have to 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. Disconnect the power wires from the power source and the connector from the power supply you intend to

remove.

2. Disconnect the safety ground wire.

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