Out-of-Band Management (OOBM)

Using ES440'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 (WAN). This terminal server capability allows operation centers to
remotely reboot, configure, and update the BIOS of a router via the ES440
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.
