Opengear Introduces the Remote Site Gateway at Cisco Live, Cisco's Annual IT and Communications Conference

LAS VEGAS, NV--(Marketwired - Jul 11, 2016) - Opengear (, a leading provider of critical infrastructure management solutions through advanced console servers, remote management, monitoring, and cellular out-of-band products, is again participating at Cisco Live  -- Cisco's annual IT and communications conference -- to unveil and demonstrate its latest solutions for highly resilient remote network management.

Opengear's award-winning products feature Smart OOB™, the company's out-of-band solution for achieving always-available secure management and control of Cisco devices -- even when primary network connectivity is unavailable. Organizations that depend on the uninterrupted availability of Cisco equipment to maintain essential business continuity rely on Opengear's solutions to safeguard network uptime through intelligent management and monitoring designed specifically for Cisco routers, switches, and security appliances.

Opengear comes to Cisco Live eager to debut its Remote Site Gateway. The newest addition to the product suite offers secure remote monitoring, access, and control over distributed networks and remote sites. The Remote Site Gateway comes ready to be paired with any existing connections and installations, making it easy to add Smart OOB management without needing to replace existing equipment. Created with rapid issue resolution and the avoidance of costly on-site technical visits in mind, the Remote Site Gateway provides true out-of-band management of critical assets, proactive monitoring of network equipment, and intelligently automated response capabilities.

Also showcased will be a key extension to the IM7200 Infrastructure Manager product line. Built for managing critical IT infrastructure, the IM7200 includes Opengear's embedded Smart OOB and key features such as environmental monitoring, audit trail logging, Zero Touch Provisioning, and enterprise grade security. New at Cisco Live will be the IM7216-2-24U, an addition to the IM7200 line that provides USB console connectivity in place of traditional RS232 serial console ports. It features 24x USB2.0 ports designed for managing console data and also has two USB3.0 host ports (like all IM7200 Infrastructure Managers) for interfacing with USB memory sticks and other devices. Uninterrupted network connectivity is provided via Opengear's Failover to Cellular™ technology, featuring IP Passthrough. Out-of-band access to remote sites is available over high-speed cellular 4G LTE, 3G, or PSTN.

Opengear recognized the need to support a USB console option and was the first in the industry to introduce USB console support (announcing support for Cisco USB console ports on all USB-equipped products during Cisco Live 2012). It now offers a variety of solutions for console management, with the flexibility to mix RS-232 and USB consoles. Anticipating increasing USB adoption by device manufacturers and seeking to future-proof console management, Opengear has extended USB capabilities to its IM7200 and CM7100 data center models in addition to all Resilience Gateway remote site managers. Each Opengear product now features two USB2.0 host ports (the newer Resilience Gateway and Remote Site Gateway ACM7000 models have four). Opengear believes USB will prove especially valuable in environments with a mix of data center and consumer-grade equipment (such as branch offices), within locations where flexibility is particularly important (such as R&D labs), and in data center environments where USB-only devices are common (or where USB capabilities make it a better choice than RS-232).

Opengear foresees that the IM7216-2-24U will offer better flexibility to network and system admins by being compatible with a broader range of current and future vendor equipment. The IM7216-2-24U's advantages include easy plug-and-play deployment, avoiding issues with pin-outs and cables or wiring. The infrastructure manager features strong GUI support for USB deployment at remote sites, power support for devices, and USB data transfer speeds faster than serial ports.

"Opengear is excited to once again be part of Cisco Live, and to exhibit and demonstrate our new solutions to customers," said Gary Marks, President, Opengear. "We're proud to display the deep capabilities of our new Remote Site Gateway and the expanded IM7200 line, our popular workhorse with added USB console connectivity and support. Both products have been designed to deliver Cisco compatibility and cater to the needs of customers operating environments based on Cisco networking equipment. With Opengear's solutions, even critical infrastructure at sites half a world away is functionally close at hand -- and remains so even when networks go down."

Founded in 2004, Opengear delivers next generation intelligent solutions for managing critical IT and communications infrastructure. Opengear's solutions, featuring embedded Smart OOB™ technology, equip our customers' networks with intelligent automation and bulletproof resilience, enabling them to optimize technical operations and secure business continuity.
