Hot-plug/Hot-swap Components
Ê Connect the power supply unit to the power supply.
I
Please ensure that the power supply unit engages correctly in the
mounting frame and is locked in position.
This is the only way to avoid the power supply unit being shaken out of
its mountings and damaged during transport.
8.1.2
Adding a Hot-plug Power Supply Unit
A second hot-plug power supply unit can be added to achieve redundant power
supply. If one power supply unit fails, the second power supply unit ensures
unimpaired further operation.
The location for an additional power supply unit contains a dummy unit. This
dummy unit must be removed before installing a second power supply unit.
Ê Remove the dummy unit from the second power supply unit location.
I
Installing/removing the dummy unit occurs in the same way as the
power supply unit (see section "Replacing the Hot-plug Power Supply
Unit" on page 74).
V
CAUTION!
Keep the dummy module for future use. If the power supply unit is
removed and not replaced with a new unit, then the dummy unit must
be reinstalled due to cooling, the applicable EMC regulations (regula-
tions on electromagnetic compatibility) and fire protection.
Ê Insert the second power supply unit into the free location (see section
"Replacing the Hot-plug Power Supply Unit" on page 74) and connect it to
the power supply (see section "Connecting the Server to the Line Voltage"
on page 49).
