You can use the Input Power Limit tab to define various settings for limiting the power consumption. The tab
contains three boxes.
Figure 47: Power Management – Input Power Limit tab
PSU Controlling
Enable General PSU Settings
This checkbox must be enabled to allow you to enter the other settings in this box.
PSU Dynamic Mode
Disabled
No dynamic power supply unit mode (default).
Standard
Dynamic power supply unit mode. This setting enables power to be saved by operating some power
supply units with a higher load and disabling others.
I
PSU Dynamic Mode together with No Redundancy (see the setting option below) can power off
the system immediately if the last power supply unit which is still active no longer supplies suffi-
cient power.
Redundancy
The selection options available depend on the number of power supply units available.
If power supply unit redundancy is selected (n+1 or n+m), the maximum standard output power available for
the system unit is reduced, but every redundant power supply unit increases the reliability and availability of
this output power level because 1 or m power supply unit(s) can fail without operations being interrupted.
Two power supply units are required for the smallest redundant PSU configuration in a BX900 system unit.
Possible values: No Redundancy, 1+1, 2+1, 2+2, 3+1.
