Antaira GNP-1600G-T 16-Port Gigabit Unmanaged Industrial PoE Switch with 16x PoE+ (300W) and -40 to 75 °C

Gigabit cameras along a perimeter or transport corridor often terminate in one outdoor cabinet, where 16 PoE+ ports and dual supplies keep the scheme simple. The GNP-1600G-T is the extended temperature build in the Antaira GNP-1600G series series: a 16-port Gigabit unmanaged industrial PoE switch rated -40 °C to 75 °C for unheated outdoor enclosures.

All of its 16 10/100/1000Base-T(X) RJ45 ports are IEEE 802.3af/at PSE ports supplying up to 30 W each. The total PoE budget is 300 W with a 56 V DC input, shared across the ports, so it sets how many 30 W devices run together. Switching is unmanaged and store-and-forward, using an 8K MAC address table, with IEEE 802.3x flow control and 9 KB jumbo frames. There is nothing to set up.

Power arrives on dual redundant 48 to 56 V DC inputs through a removable 6-pin terminal block, so a second supply can take over if the first fails. An alarm relay contact rated 1 A at 24 V DC flags a lost feed to a PLC or alarm panel. Reverse polarity and overload current protection are built in, and the GNP-1600G-T draws 10.64 W at full load without PoE. ESD protection reaches 6 kV contact and 8 kV air, with EFT and surge to 2 kV.

The GNP-1600G-T operates from -40 °C to 75 °C in an IP50 aluminum housing for DIN rail or wall mounting, with shock, vibration and free fall tested to EN 60068-2-27, -2-6 and -2-31. It complies with UL 62368-1 (MET) and carries LVD, CE and FCC Class A marks; Antaira lists it as TAA and NDAA compliant and backs it with Antaira’s 5-year warranty. The GNP-1600G is the same switch rated -10 °C to 70 °C, the GNP-1600-T is the Fast Ethernet equivalent where 100 Mbps is enough, and the GNX-1600G-T drops PoE for a wide 12 to 56 V DC input.
