4 Powering
4.1 Plugin
Each plugin is fed via the subrack backplane with (dual) -48VDC (referenced to 0VDC of the ex-
change battery). The minirack mechanics has two -48VDC inputs and on model SZ.876.V100 also
an AC powering input. The plugin generates the used voltages onboard.
The ground reference of all voltages on the secondary side of the plugins DC/DC-converter is tied
to FPE (Functional Protective Earth).
Additionally, the plugin is fed over the backplane with an auxiliary +5VDC supply (referenced to
ground) generated on the ACU. The only purpose of this voltage is to drive the alarm circuitry on
each plugin, even in the case of a failure of the plugin onboard DC/DC-converter.
4.2 Tabletop
The tabletop modem is normally powered locally from an AC/DC adapter with 48VDC output. Power
adapter SZ.410.080.V1E is available from Schmid Telecom to power the tabletop modem.
Caution: Do not connect a 48VDC supply directly to the “AC/DC adapter” connector! High voltage transients
from the DSL line may damage other equipment connected to the battery. A DC/DC converter with
4kV transient isolation voltage must be used in this case.
Caution: The local supply voltage input is protected against reversal of polarity but not fused. Appropriate
fusing has to be done externally.
If connected to a Watson 5 plugin modem with remote powering functions then the tabletop can
also be powered through the DSL. Switching between local and remote powering is done automati-
cally with local powering taking precedence over remote powering.
Note: Remote powering functions are only available on plugin modems with E1 or nx64 user interfaces.
The Watson 5 Ethernet plugin does not support remote powering of a tabletop.
The ground of the tabletop modem is normally floating when referenced to earth. A ground connec-
tor (Faston type) is available on the rear panel of the modem.
