Remote Out-of-Band Management via 3G/4G Modem

When network equipment is located in extremely remote locations, the task of implementing an effective out-of-band management solution can present a difficult challenge. At remote installations sites that are far off the beaten track, network cables and phone lines are often unavailable, forcing network engineers to rely on other means for out-of-band access to networked devices. One effective solution to this type of application is an out-of-band management solution based on communication via 3G/4G modem.

Often, the very nature of the application requires that network equipment must be installed at locations that are miles away from normal network cable and phone communication. This type of situation is extremely common in the petroleum industry, mining industry and transportation industry, and also often encountered in cell tower management, wind farm management and other applications that demand network communication with extremely remote sites.

Regardless of the remote nature of these applications, an effective out-of-band management solution is still required in order to ensure prompt access to diagnostic and troubleshooting functions when problems arise at remote network equipment sites. When communication via network cable or phone line is unavailable, and communication via satellite is deemed not sufficiently reliable due to weather conditions and other factors, that often leaves cellular broadband communication via 3G/4G modem as the only workable solution for out-of-band management.

When a network element at a remote site crashes or fails to respond, and 3G/4G modem based out-of-band management solution enables administrators to quickly access power reboot and switching functions as well as console port command functions at the remote site. These capabilities allow network managers to reboot unresponsive devices, switch off nonessential devices in order to conserve resources, or invoke console port commands in order to change configuration parameters or run diagnostic routines.

In addition to providing an effective out-of-band management solution for remote network equipment applications, there are also cases where communication via 3G/4G modem serves as the only means to contact remote network elements. That said though, regardless of whether an in-band or out-of-band solution is required, the key to implementing workable cellular broadband based network management is the presence of a switched PDU or console server that is compatible with a 3G/4G modem. WTI offers a comprehensive selection of switched PDU products and console server products that can easily be connected to a 3G/4G modem and used as a part of a variety of different cellular broadband based network communication applications. WTI Switched PDUs and console servers support communication via 3G/4G modem, and also provide robust security and authentication features, remote monitoring and alarm functions and other valuable features that help to streamline and simplify the task of managing network elements at extremely remote sites.
