Antaira GNP-0500 5-Port Fast Ethernet Unmanaged Industrial Network Switches with 4x PoE+ (90W) and Extended Temperature Options

Small surveillance and access control schemes often need power and data for four devices plus one uplink, and a separate supply at each camera or reader adds cabling and points of failure. The Antaira GNP-0500 series covers that with unmanaged industrial PoE switches that pass traffic as soon as they are powered: five Fast Ethernet RJ45 ports in a slim IP30 metal housing for a DIN rail or a wall, with nothing to configure on site.

Every GNP-0500 has five 10/100Base-T(X) RJ45 ports. Four of them are IEEE 802.3af/at PSE ports that supply up to 30 W each, and the fifth is a non-PoE port for the uplink. The total PoE budget is 90 W with a 56 V DC input, shared across the four ports, so it sets how many 30 W devices run together. Switching is unmanaged and store-and-forward, on a 1 Gbps switching fabric and a 1K MAC address table, with IEEE 802.3x flow control and IEEE 802.1p class of service. DIP switches turn on broadcast storm protection and QoS; otherwise there is nothing to set up. Power arrives on a single 48 to 56 V DC input through a removable 3-pin terminal block. Reverse polarity and overload current protection are built in, and each switch draws 1.68 W at full load without PoE. ESD protection reaches 6 kV contact and 8 kV air, with EFT and surge to 2 kV.

The series has two builds that differ only in temperature rating. The GNP-0500 is the standard build, rated -10 °C to 70 °C for indoor panels and heated cabinets. The GNP-0500-T is the extended temperature build, rated -40 °C to 75 °C for unheated outdoor enclosures, roadside cabinets and camera poles. Both share the same ports, switching, power input and approvals, so a scheme can mix them by location. For the same port count without PoE, the GNX-0500 series series runs from a wide 9.6 to 60 V DC input.

Antaira names industrial automation, IP surveillance, traffic monitoring, security, transportation and telecom among the applications for the GNP-0500 series. Both models are tested for shock, vibration and free fall to EN 60068-2-27, EN 60068-2-6 and EN 60068-2-31, store from -40 °C to 85 °C and tolerate 5 to 95% non-condensing humidity. They comply with UL 62368-1 (MET), carry LVD, CE and FCC Class A marks, are listed by Antaira as TAA and NDAA compliant and come with Antaira’s 5-year warranty. We supply the GNP-0500 across the USA and can help choose the temperature grade, size the DC supply and specify the cabling for each cabinet.
