clicks into place.

I Make sure that the power supply unit engages correctly in the installation
frame and is locked in position.

its mountings and being damaged during transportation.
8.1.1.2 Adding a hot-plug power supply unit
A second hot-plug power supply unit can be added to ensure a redundant power
supply. If one power supply unit fails, the second power supply unit ensures that
operation continues unimpaired.
The slot for the second hot-plug power supply unit contains a dummy module,
which must be removed before installing the second power supply unit.
Ê Remove the dummy module from the second power supply unit slot. To do
this, remove the screw securing the dummy module, push the dummy
module upwards and unhook it at the top.
V CAUTION!
Store the dummy module in a safe place. If the power supply unit is
removed and not replaced with a new unit, then the dummy module
must be reinstalled due to cooling, the applicable EMC regulations
(regulations on electromagnetic compatibility) and fire protection.
Ê Insert the second power supply unit into the free slot (see section “Replacing
the hot-plug power supply unit” on page 92) and connect it to the mains (see
section “Connecting the server to the mains” on page 61).
