A DC Powered Remote Console Server Provides the Perfect Fit for Remote Network Site Administration

Due to their very nature, remote network equipment sites are often located far off the beaten path, well out of the reach of network cables and AC power lines. In cases like this, a remote console server (http://www.wti.com/c-47-remote-console-servers.aspx) that runs on DC power and supports secure communication via dial-up and satellite modem provides the only workable solution for out of band management.

In order to provide out of band communication capability to extremely remote network equipment site, network engineers are often faced with the choice of either setting up the installation for DC power and modem communication, or spending an inordinate amount of time and money to run DC power lines and network cables out to the middle of nowhere. Usually, the obvious choice is to equip the remote network installation with a DC powered remote console server that supports dial-up modem and/or satellite modem communication. This might seem like an easy solution, but it can sometimes be challenging to find remote console server products that support both DC power and modem communication.

When searching for a DC powered remote console server for extremely remote network sites, it’s important to make certain that the remote console server supports appropriate security features to prevent unauthorized access to console port command functions at the remote site. Obviously, the remote console server should include some sort of password protection, but it’s also helpful if the remote console server includes a dial-back or call-back feature to provide an additional layer of security for modem communication. Typically, a callback feature allows network administrators to define a contact number for each registered user account. When the callback feature is properly configured, users who attempt to gain access via modem are not granted immediate access to console port command functions. Instead, users are prompted to enter their password; if a valid password is entered, the callback feature will then disconnect and call the user back at the number that has been predefined for their account. In some cases, the callback feature can also be configured to prompt users to re-enter a valid password upon callback, providing further insurance that only authorized users are allowed to access command mode functions.

Typically, DC powered remote console servers are powered by -48 volt DC power, providing compatibility with remote network equipment sites that rely on battery power instead of AC. DC power usually provides a much more stable power source than could be achieved using an AC power generator, and also provides a good fit for applications where space is limited and environments such as power line monitoring stations where DC power is readily available.

When DC power compatibility and support for modem communication are combined, this provides the ideal solution for out of band access to remote network installations. In applications where the remote nature of a network equipment site mandates the use of DC power and modem communication, out of band management capability is an extremely vital element for maintaining and supporting important network devices at the remote site, without the need for a constant parade of expensive, time-consuming service calls to the remote site, every time a device hiccups or fails to respond. When one considers the power environment and communication requirements of remote site administration, it quickly becomes obvious that a DC powered remote console server that supports modem communication often provides the only workable solution for out of band access to vital equipment at extremely remote network equipment sites sites.
