Standard power supply
Ê If applicable, connect the mains plug to a grounded mains outlet in the in-
house power supply network.
Ê Connect the power cord to the power supply unit.
Figure 10: Example: Locking the cable tie of a standard power supply unit
Ê Thread the cable tie through the eye (1).
Ê Pull the cable tie tight to secure the power cord (2).
The insulated connector cannot now be disconnected from the server
accidentally.
Redundant power supply
Ê If applicable, connect the mains plugs to power outlets of the rack socket
strip.
I To provide true phase redundancy, the second power supply unit
should be connected to a different AC power source from the other
power supply unit. If one AC power source should fail, the server will
still continue to run.
Ê Connect the power cords to the power supply units.
Ê Ensure that the status indicator on the power supply unit is lit green (see
section "Indicators on hot-plug power supply units (slide-in units)" on
page 305).
