1.24 NT24k-12SFP-DM4-POE
The versatile NT24k-12SFP-DM4-POE managed switch features IEEE 802.3af/at Power over Ethernet Plus
(PoE+) on eight Gigabit copper Ethernet ports plus four dual mode SFP ports, housed in a hardened metal DIN-
Rail enclosure with redundant 22-49 VDC power inputs. Designed to handle the most demanding environments,
the NT24k-12SFP-DM4-POE offers wire-speed throughput, expanded shock and vibration ratings and wide -40 °C
to 80 °C operating temperature ratings. IGMP auto-configuration, IEEE 802.1x port-based network access control
with RADIUS remote server authentication and Multi-Member N-Ring fast healing technology ensure quick
deployment and robust secure network communications in alternative energy, transportation, water/wastewater,
and manufacturing applications.
