Appendix C: Frequent Questions
Q:
What is the maximum heat dissipation of the PoE370U-XXX-X-XX-R with maximum load?
A:
AC mode
≈
125W
DC mode
≈
20W
Q:
What is the function of the “current share” pin on the DC Power connector? Are there any
protocols or procedures associated with it?
A:
The DC solution contains 3x 500W 50V rectifier modules (1000W N+1) with custom cables
available for connection between the rectifier rack and up to 4 midspans. The current share
pin is an option which could be used to have the power supply inside the midspan current
share with the rectifiers. There are no protocols or procedures associated with it other than
it’s designed only to work with our rectifier system and even then its not perfect sharing due
to the inrush limiting components inside the midspan located on the DC input.
Q:
What type of Display Properties settings is required to run the PoE370 GUI (Serial
Communication)?
A:
16-Bit: 1024 X 768 pixels, 1280 X 1024 pixels
32-Bit: 1024 X 768 pixels, 1280 X 1024 pixels
If the settings are set to be at least the values shown below, the edges of the GUI window will
be cropped.
16-Bit: 640 X 480 pixels, 800 X 600 pixels
32-Bit: 640 X 480 pixels, 800 X 600 pixels
