Introduction JHA-IGS24HP is a plug-and-play unmanaged industrial PoE switch. This switch provides 4 10/100/1000Base-T(X) Ethernet port and 2 1000Base-X SFP slot, the Ethernet port support Power-over-Ethernet (PoE) function. The switches are classified as power source equipment (PSE), and when used in this way, the switches enable centralization of the power supply, providing up to 30 watts of power per port and reducing the effort needed for installing power. The switches can be used to power IEEE802.3af/at standard devices (PD), eliminating the need for additional wiring. JHA-IGS24HP support CE, FCC, RoHS standard, adopt industry standard design, IP40 protection, rugged high-strength metal case, power input (DC48-55V). The switch support IEEE802.3, IEEE802.3u, IEEE802.3x with 10/100/1000Base-T(X), full/half-duplex, and MDI/MDI-X auto-adaptation, the -40-85℃ operating temperature, can meet all kinds of industrial environment requirement, providing reliable and economic solution for your industrial Ethernet network.
