Unpack the new QM561 power supply unit, keeping the packaging materials. 2. Check the status of both the QM561 to be replaced and the QM561 that is to remain in the interconnect. Ensure that the QM561 that is to remain in the interconnect is operating correctly. 3. Activate the release latch on the QM561 to be replaced and carefully slide the module out of the interconnect. 4. Insert the replacement QM561 power supply unit and slide it into the slot until the connector is docked and the latching mechanism is activated. 5. Ensure that the replacement QM561 is operating correctly. 6. Pack up the old QM561 power supply unit using the materials supplied and return it to the supplier for repair or replacement.
