3.3. Power Supply Unit
This server is designed with two 1400W power supplies. When the server is equipped with dual
power supply, the hot-swappable redundant function is provided. If one power supply does not
work, you can replace the failed power supply without powering off the server, because the other
one can take the place of the failed one.
The location of power supplies on the server is shown below:
Figure 3.4. Power Supply Locations
Partial redundancy is supported on design with a throttling feature to downgrade pow-
er consumption when a PSU is faulty or has been removed. A single faulty PSU can
be replaced without system shut down.
DISCONNECT THE POWER SUPPLY UNIT FROM THE POWER SOURCE BE-
FORE REMOVING PSU. FAILURE TO DO SO COULD RESULT IN DAMAGE TO
THE EQUIPMENT OR PERSONAL INJURY.
The redundant power supply unit can be replaced without shutting down the system.
3.3.1. Removing a Power Supply Unit
1. Pull up the handle.
2. Press the retaining clip on the right side of the power supply along the direction of the arrow.
3. At the same time, pull out the power supply. (The power supply takes considerable force to re-
move.)
