3.3.4 Buffer battery for the modem module during power fail-
ure
The buffer battery for the modem module can optionally be connected to
the ST1 of the power supply board to ensure that data continues to be
transmitted, even in the event of a power failure. For technical data of the
battery, see chapter 3.2.2 "Battery power supply for the integrated modem".
3.4 Power supply for the DL230 with Power over Ethernet
(PoE)
If the DL230 is equipped with an Ethernet module and if the Ethernet net-
work (or a switch) provides the Power over Ethernet function, the DL230
can be supplied with power from the Ethernet module. An integrated power
supply is not required.
