Emergency Access to Command Functions via Dual Ethernet Console Server

In many cases, the challenge of dealing with a network outage is a fairly simple proposition. Once one has determined which network element has caused the outage, it’s simply a matter of connecting to the console port on the afflicted device and changing a few configuration parameters or running a troubleshooting routine. Unfortunately, in the era of colocation the task of accessing a malfunctioning device can often prove to be a bit more of a challenge if that device is located in a remote data center or locked up safely inside of a distant equipment enclosure. In cases like this, a Dual Ethernet Console Server can provide network administrators with redundant access to remote devices, even when primary network communication is not available.

A network redundancy solution that includes a Dual Ethernet Console Server provides support personnel with to network avenues for access to remote console port command functions. Typically, the Dual Ethernet Console Server is connected to both a primary network and an emergency, secondary network. If communication via either of these networks is unavailable, support personnel can simply switch to the other network in order to access problematic devices and resolve the problem that caused the network outage.

Ideally, the Dual Ethernet Console Server should include separate IP routing tables for each available Ethernet port in order to simplify the process of connecting to the console server. Once connected to the console server, support personnel can then access console port command functions on any network element that has been attached to the Dual Ethernet Console Server in order to check device status, review configuration elements or take other actions to restore network communication.
