  • SISGM1040-284-LRT-back

The SISGM1040-284-LRT is a managed switch suitable for connecting devices in hardened environments. The switch has 24Gbps switching capacity. The switch also includes the embedded Device Management System (DMS) 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 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.
