Lantronix LM83X – Advanced Out-of-Band Management


The Most Advanced Console Server

Designed from the ground up as a modular platform able to act independently from the network to remotely monitor, manage and control up to 104 devices over a serial console connection, the LM83X is the fifth generation Local Manager.

Configurable to manage 8-104 devices directly over RS-232 connections, the LM-Series is also capable of managing virtual environments and SD-WAN deployments to increase resiliency. Virtual ports and port forwarding let you use the out-of-band platform as a resilient toolbox for secure access to all your network infrastructure, automation of day-to-day management, and the go-to source of information and response during network emergencies.



The Lantronix LM83X provides persistent connectivity to managed devices through both in-band and out-of-band (OOB) channels. In the event of a primary network loss, WAN Traffic Failover allows traffic to continue flowing over the OOB link. The LM monitors devices locally using the built-in intelligence of the Lantronix Local Management Software, performing maintenance or recovery tasks as needed, and constantly enforcing security policies—regardless of the state of the network.

Unparalleled management control is possible by interfacing directly through the console port of the devices it manages. This connection enables always-on, localized, round-the-clock management for your IT infrastructure. With integrated functionality for access, control and enforcement, Lantronix LMs can automate as much as 70% of routine network maintenance functions and autonomously address the majority of issues that cause network-related outages. Problems that today might require IT staff on-site physically to resolve are detected by the Lantronix in seconds, and fixed in minutes.
