In addition to serving as a vital element in network redundancy applications, a Dual Ethernet Console server can also help to provide wireless access to inaccessible network elements in lights out data centers and locked equipment cabinets. This type of implementation is particularly helpful in server rooms and other situations where tech support “crash carts” are used to provide quick access to vital network elements during emergencies and outages.

In large network installations, tech support personnel often find it useful to have an isolated maintenance network, reserved for use as an exclusive avenue to upgrade firmware, perform routine diagnostic functions and deal with network emergencies that may have disrupted access via the primary, user network. When a Dual Ethernet Console Server is included in the maintenance network, this provides both tech support personnel and rank-and-file users with a means to access console port command functions on various network elements.
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 Dual Ethernet Console Server can provide network administrators with a variety of different options for accessing console port command functions on remote or inaccessible network elements. This is especially true if the Dual Ethernet Console Server includes separate routing tables for each Ethernet port. In addition to serving as a vital element in network redundancy applications, a Dual Ethernet Console Server can also simplify remote console access in applications that feature an isolated maintenance network and can also provide additional communication options for server room crash carts.
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.
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.
