Features of PoE Mode
– Up to twelve PoE interface modules with a total of 24 ports can be operated at the
same time in an MMS.
– Configuration is still possible if the interface module is not plugged in or the
48 V supply is not connected.
– PoE management and PoE information are only available if the interface module is
plugged in and there is a connected 48 V supply.
– The following management functions are available:
- Display error states for each port and communicate via the alarm contact
(yes/no)
- Connect/disconnect voltage for each port
- Switch current limitation on or off for loads classified as Class 1 devices
– Send Traps when the PoE status changes
– The following diagnostic information is displayed:
- No error
- Surge voltage/undervoltage
- Thermal error
- Overload
- Disconnected load (the current consumption at this port is less than
10 mA, the supply voltage is disconnected by the PoE module)
- No 48 V supply
The PoE interface module is supported by firmware Version 4.0 or later. Firmware
Versions < 4.0 treat the module as a standard RJ45 interface module. The module can
operate in PoE mode without management and without support from the firmware and
hardware (system bus) (see note below). No configuration options and no diagnostic
data are available, connected termination devices are nevertheless supplied with power.
The use of the PoE interface module requires the application of system bus firmware
5.00 or later in the head station and system bus firmware 4.00 or later in the extension
modules. If this requirement is not met in the head station or in any extension module,
then PoE management is not available in the entire system. The system bus firmware is
displayed on the "Device Information/General" web page.
PoE management and PoE information are only available if the 48 V supply is connected
to the relevant PoE interface module. The ports can be used as standard RJ45 ports if
there is no connected supply.
