Note
Only one port and one mode of operation (PD or PSE) can be selected at a time. Any other
combination of jumpers is invalid.
Installation
Ethernet connectors in line with conduit holes
A fast disconnect circuit protects from someone inadvertently wiring Gateway to high
voltage or AC Mains (circuit resets when improper power is removed)
More area freed up for installer wiring in lower section
Total number of circuit boards, wires and connectors is greatly reduced
Gateway gets its power off the ethernet port selected
Gateway gets its power from a local power supply and sends power down the ethernet port selected to another
device
Enabled; this enables the PSE operation
Disabled; this disables the PSE operation
