The ITP-800A-8PH24 is an unmanaged, Fast Ethernet, PoE switch, that provides 8 x 10/100Base-TX PoE+ Ethernet ports. This Ethernet switch is designed for industrial applications in harsh environments with Ethernet ports that utilize M12 connectors to ensure water- tight, robust connections and guarantee reliable operation against environmental disturbances such as vibration and shock. The ITP-800A-8PH24 series Ethernet switches are compliant with EN50155, covering operating temperature, power input voltage, surge, ESD, vibration, and shock, thus making these switches suitable for industrial applications in vehicle, rolling stock and factory automation.

Bypass Relay Function for ITP-800(-E)

ITP-800(-E) provides two copper interfaces with auto bypass relay function in the event of sudden power loss particularly in daisy chain or linear topology. When power failure occurs in one of the switches, the bypass relay activates the bypassing mechanism by interconnecting internal circuits automatically to ensure that links between switches operate without interruption .

Mounting for IFS-401

Wall-Mounting Installation

The Ethernet Switch can be mounted on the wall using the attached wall-mounting bracket with two wall-mounting holes. The installation is simple and easy and only requires to prepare two appropriate wall screws for mounting the Ethernet Switch. After you find a suitable place to wall-mount the Ethernet Switch, remember to align the mounting holes (marked X in Figure 11) with wall screws. Then, fasten the two wall screws securely to prevent the Ethernet Switch from falling.
