Out-of-Band Management (OOBM)

Using the ES450 device's serial port to connect to the console port of the router, IT
administrators can troubleshoot and repair network equipment over wireless wide area
networks (WANs). This terminal server capability allows operation centers to remotely
reboot, configure, and update the BIOS of a router via the ES450 enterprise gateway
using Reverse Telnet and SSH protocols. As a result, remote personnel no longer need to
manually reset their networking equipment and IT administrators can dramatically reduce
the number of field visits.
