6.9.2 PoE 90W power supply

The product can be powered by 90W PoE according
to standard IEEE 802.3bt (CLASS 8) or via a PoH
power injector.
The PoE injector must have at least 90W power.
By default, the product is configured to work
according to standard IEEE 802.3bt.
ThePoH backward compatibility mode must be
enabled with the following power injector.
• VIDEOTEC injector OHEP90INJ.
• VIDEOTEC injector OHEP90INJO.
As described in the VIDEOTEC PSINJ95CH1 accessory
manual, depending on the position of the PoE Mode
switch, the injector can operate in different ways:
• IEEE802.3bt (Standard position).
• PoH (Legacy position).
If the product is powered by two sources of power
simultaneously (24V and PoE 90W), only the 24V line
will be used, disabling the PoE 90W power supply.
A list of tested power injectors is available upon
request.
6.9.2.1 PoH backward compatibility mode
enabling
There are two DIP switches on the connector board
which allow the PoH backward compatibility mode
to be enabled (S1, S2, Fig. 17, page 23 and Fig. 18,
page 23).
