A Dual Ethernet Console Server Provides More Options for Remote Console Access

Console servers provide a vital function for network managers and support personnel, by enabling secure, out-of-band access to console port command functions on remote network elements without the need to travel to the installation site in person. Although this function is absolutely vital for remote network management applications, a console server can also provide other capabilities if the console server includes dual Ethernet ports.

In addition to out-of-band access applications, dual Ethernet console servers also lend themselves well to network failover applications, network redundancy applications and applications that require remote access via cellular broadband.

In network failover applications, a dual Ethernet console server can be connected to both the primary network and secondary network in order to ensure that both networks can be used to access console ports on remote network elements. If network problems arise and take down the primary or secondary network, network administrators can then connect to the dual Ethernet console server via the remaining network in order to communicate with the network element that caused the outage in the first place. This allows tech support personnel to quickly address the problems that caused the network outage and restore service quickly without the need for a service call.

Network redundancy applications are generally designed to provide two parallel corridors for network traffic: a production network for general users plus a maintenance network for use by support personnel. A well designed network redundancy solution reduces traffic on the production network and provides network administrators with a dedicated network path that can be used for network management, update and configuration tasks. In a Network Redundancy application, the dual Ethernet console server can be connected to both the production network and maintenance network in order to provide both support personnel and general users with access to console port command functions on remote network elements.

Network applications that include cellular broadband access capabilities are commonly found in situations where it is not economically feasible or practical to communicate with a remote network element via cable or dial-up. This is often the case in any application that includes extremely remote network installations, so far off the beaten path that a network cable or phone line is not available. In this case, the dual Ethernet console server allows connection to both the local network at the remote site and to a router and 3G/4G modem that provides remote access via cellular broadband. This allows access via cellular broadband to local network at the remote site without sacrificing a valuable serial port that might be needed for connection to a console port on a device at the remote site.

In addition to the examples cited here, a dual Ethernet console server can also provide the perfect fit for any other application that requires connection to two network cables or requires connection to both a network cable and a modem.
