A Console Access Server with a Lost Communication Alarm – Detect Communication Problems with Remote Devices

Console access servers essentially provide an “emergency doorway” into your network, allowing timely access to servers, routers, switches and other critical network devices when normal avenues of communication are not present. When a remote network element crashes or freezes, a console access server provides a convenient way to access critical control functions on remote network elements, without the need to actually travel to the installation site in person.

When you consider value of the remote management capabilities provided by a console access server, it quickly becomes apparent that it’s of utmost importance that communication between the console access server and connected network devices is always ready and available when you need it. In order to allow network administrators to monitor the stability of out of band communication with remote devices, WTI console access servers include a Lost Communication alarm, which constantly monitors communication with each network device connected to the console access server, and automatically notifies administrators when that connection is lost.

When the Lost Communication alarm is triggered, the console access server can notify administrators via email, text message, SNMP trap or Syslog message. This allows administrators to detect communication problems with attached devices, and address those problems before out of band communication with the remote device becomes the only way to correct the problem without an expensive service call.

The Lost Communication alarm can send notification to up to three user-defined email addresses when communication with an attached device is lost. In addition, the Lost Communication alarm also includes an option that allows the console access server to send additional notification to administrators if communication with a connected device is later restored. This enables network administrators to be certain that when they need to access a remote network device in order to correct a problem, communication with the remote device will be readily available.

When your primary network is down, the console access server often provides the only way to address problems at a remote network site without physically traveling to the site in person. This can be an extremely critical capability, especially in cases where problems at a remote site bring the entire network to a halt. In situations like this, there isn’t time to send a service team out to the remote site to correct the problem; users need their network now (if not sooner,) and the faster the problem can be corrected, the happier those users will be.

It’s absolutely vital that a console access server can always provide access to command functions when they’re needed; without quick access to remote devices, the whole purpose of the console access server is defeated. The Lost Communication alarm allows network administrators to know about communication problems with remote devices and fix those problems before quick, secure access to remote network devices is really needed.
