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
•
