Managed Hardened Gigabit Ethernet PoE+ Switch
(8) 10/100/1000Base-T PoE+ Ports + (4) 100/1000Base-X SFP Slots

The SISPM1040-384-LRT-C is a managed PoE+ switch suitable for connecting and powering devices in hardened environments. The switch can supply up to 30 Watts per port on all (8) ports simultaneously. The switch also includes the embedded Device Management System software that provides the advanced tools necessary for total management of all IP addressable devices. The unique DMS provides security integrators with lower overall cost, less downtime and easier management of the entire PoE+ network.

Lantronix’ hardened switches are certified to operate reliably in harsh environments such as those found on factory floors, outdoor enclosures or other challenging environments.
