Further there is a button to disable the internal fan for
approximately 5 seconds (not implemented yet). This allows
the user to take input power measurements without fan
consumptions to check efficiency compliance to the Climate
Saver Computing Platinum specification.

The front-end has 2 front LEDs showing the status of the
supply. LED number one is green and indicates DC power is
on or off, while LED number two is bi-colored: green and
yellow, and indicates DC power presence or fault situations.
For the position of the LEDs see Figure 5.
4.2 GRAPHICAL USER INTERFACE
Power-One provides with its “Power-One I
2
C Utility” a
Windows® XP/Vista/Win7 compatible graphical user
interface allowing the programming and monitoring of the
PFE1100-12-054ND Front-End. The utility can be
downloaded on
www.power-one.com
and supports both the
PSMI and PMBus™ protocols.
The GUI allows automatic discovery of the units connected
to the communication bus and will show them in the
navigation tree. In the monitoring view the power supply can
be controlled and monitored.
If the GUI is used in conjunction with the PFE1100-12-
054ND Evaluation Kit it is also possible to control the PSON
pin(s) of the power supply.
The order of the criteria in the table corresponds to the testing precedence in
the controller.
Figure 1: I
2
C Bus to uC (Graphical User Interface)
The monitoring screen also allows to enable the hot-standby
mode on the power supply. The mode status is monitored
and by changing the load current it can be monitored when
the power supply is being disabled for further energy
savings. This obviously requires 2 power supplies being
operated as a redundant system (like the evaluation kit).
Note:
The user of the GUI needs to ensure that only one of
the power supplies have the hot-standby mode enabled.
