SCALANCE X414-3E power module
The power module is located in slot 2.
The power module can be supplied with power redundantly over two inputs. The two power
inputs are isolated from each other, there is no power distribution. If redundant power feed-in
is used, the switch is supplied solely by the section of the power module with the higher
output voltage.
The front 4-pin connector is used for the power supply. The input voltage is 24 V DC (20.4 –
28.8 V). The signaling contact supplies the fault status at the rear 4-pin connector. If there is
a fault, the contact opens.
Figure 3-11 Slot of the power module
The following can be signaled over a floating signaling contact:
● Power failure.
The power supply monitored is selected in the fault mask.
● Bad link status of a port.
(Bad connector or no connection to partner device). The port monitored is selected in the
fault mask.
● Change to the DIL switch during operation.
Possible inconsistency between the switch setting and the actual operating state, The
switch setting is adopted only after a restart.
If the SCALANCE X414-3E is set as the redundancy manager, the following errors are also
reported:
● Bad link status of the ring ports, regardless of the status of the fault mask.
● Configuration of a second IE Switch X-400 as redundancy manager in the same ring.
