Lantronix SESPM1040-541-LT-PD is the PoE-powered PD version of the SESPM Series self-enclosed managed hardened Gigabit Ethernet PoE++ switch. It provides (4) 10/100/1000Base-T IEEE 802.3bt compliant PoE++ ports and (1) combination 10/100/1000Base-T RJ-45 or 100/1000Base-X SFP port. The switch is a Layer 2 managed switch for security and surveillance, PoE lighting, digital signage and other applications. It is self-enclosed in an outdoor NEMA 4X/IP66 rated enclosure and can be mounted on a wall or side of a building; optional brackets are available for pole mounting. This PD version requires PoE power from an IEEE 802.3bt Type 4 Class 8 compliant PSE, or it can receive power over copper cable running parallel to a fiber optic cable for data. It also includes a 12V Aux port that can provide auxiliary power to a PC, lighting or other accessories. NFC allows simple, repeatable configuration using an app on a mobile device before connecting or powering the switch. Bluetooth Low Energy allows remote access to alarm information and equipment settings without requiring physical access.
