Commissioning
• Attach the 4-pole terminal block
• Properly attach the voltage connector to the terminal. Consider polarity, see Fig. 2
• Plug in terminal
• Connect grounding
• Switch on separate power supply
CAUTION: Excessively high supply voltage may damage the device as well as connected end
devices.
NOTE: Please attach all connectors as described and connect the PoE load to the RJ45
connector first and only then switch on the separate power supply. Considerable currents flow
with high PoE loads. If the 4-pin terminal or the PoE sink (PD) on the RJ45 connector is
plugged in or unplugged under load, this can lead to an electric arc, which may damage the
corresponding connectors or the media converter.
Alarm relay
The media converter is supplied with an alarm relay, see Fig. 2. When supply voltage is on, the
normally open contact of the relay is in the open switching state. If no supply voltage is
detected, the relay closes. The relay can be wired with a maximum test current of 1A at
24VDC.
DIP switch
The DIP switch on the front of the PC-HPMC101-GE is required for setting the data rate of the
SFP used. The electrical interface on the RJ45 connector automatically negotiates the used
data rate 10, 100 or 1'000Mbit/s with the connected device using the auto negotiation function.
There is no such automatic negotiation with the optical plug-in units, the SFPs. Therefore, the
data rate of the SFP used is set via the lower DIP switch. The lower DIP switch must be set to
the corresponding position "100" or "1000". The upper DIP switch has no function.
NOTE: Disconnect the media converter from power and put it back into operation to
activate a new DIP switch setting.
