6 Secure the 1900 W DC PSU in the power supply bay by rotating the latches toward each other until
the unit clicks into place.
Make sure that both latches engage properly and that they both latch securely.
7 To install more PSUs, repeat steps 3 through 6.
8 After all the PSUs are installed, re-attach a power supply retainer on each side of the power supply
bay as follows:
a Set the retainer against the power supply with the rubber cushion toward the power supply and
the captive retaining screws aligned with the side of the BlackDiamond 20808 chassis (see
