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

In remote network management applications, console servers are used to provide administrators and support personnel with a secure, out-of-band avenue for communication with console ports on distant network elements. Most network engineers are fairly familiar with the basic out-of-band communication functions provided by a console server, but not all realize that a console server with dual Ethernet ports can provide additional communication capabilities beyond basic out-of-band management.

In addition to providing reliable out-of-band access to console port command functions on remote network devices, Dual Ethernet console servers can also be used in network failover applications, network redundancy applications and applications that rely on cellular broadband for out-of-band access to remote devices.

In the case of network failover applications, a dual Ethernet console server is often used to ensure that both the primary network and secondary network are able to access console ports on remote network devices. In network failover applications, a dual Ethernet console server is typically connected to both the primary network and secondary network. In the event that network problems arise and interfere with communication on the primary network, this provides administrators and support personnel with a means to communicate with critical network elements in order to resolve the problem that caused the network outage without the need for a service call.

Dual Ethernet console servers are also commonly employed in network redundancy applications that include two separate, parallel corridors for network communication: a production network for basic users, plus a maintenance network that provides access for support personnel. The primary goal of a network redundancy application is to both reduce user traffic on the production network, while providing a dedicated, exclusive maintenance network path for use in network management, firmware upgrade and configuration tasks. In this type of application, the dual Ethernet console server is connected to both the production network and maintenance network in order to allow both basic users and support personnel to access console ports on remote network elements.

In network applications that rely on communication via cellular broadband, a Dual Ethernet console server allows connection to both a standard network cable for communication with local devices, plus a 3G/4G modem for remote broadband communication. This type of application is typically found in situations where the remote nature of the network installation makes communication via secondary network or dial-up connection impractical. In this case, a dual Ethernet Console Server provides remote access to networked elements at a distant equipment sites via cellular broadband.
