PoE Ports
DMS-1250-10SP
DMS-1250-12TP
DMS-1250-10SPL
Supports the following:
• IEEE802.3af/at PoE+ compliance (for DMS-1250-10SP/DMS-1250-
12TP)
• IEEE802.3af/at/bt PoE++ compliance (for DMS-1250-10SPL)
• The auto-discovery feature automatically recognizes the connection of
the PD device and provides power
• Automatically disable ports if the port current is over 400~450mA while
other ports will remain active
• Active circuit protection automatically disables the port if there is a short
while other ports remain active
• For 802.3af/at/bt capable devices will provide the power for the following
classifications below:
Class Usage Max Power used by PD
0 Default 0.44 Watt to 12.95 Watt
1 Optional 0.44 Watt to 3.84 Watt
2 Optional 3.84 Watt to 6.49 Watt
3 Optional 6.49 Watt to 12.95 Watt
4 Optional (802.3at Only) 12.95 Watt to 25.5 Watt
