where:
I
– interface (1 - one Ethernet an one SHDSL; 2 – one Ethernet PoE
output and one SHDSL PoDSL input; 3 – one Ethernet PoE input and
one SHDSL PoDSL output; 4 – one Ethernet PoE output and one
SHDSL).
P
– power (1 – 3,3V; 2 – 12V; 3 – 24V; 4 – 48V; 5 – 48V PoE; 6 – 240V
PoDSL).
E
– enclosure (1 – indoor case; 2 – IP66 case; 4 – indoor case with
mounting on DIN-rail; 5 – IP66 case with mounting on DIN-rail;)
With a maximum load of PoDSL (17W) for SG-17B-351 modem power
consumption is about 20 W, which corresponds to the class of consumption
PoE +
