Dual WAN Out-of-Band Management Solution for Juniper EX3300 Series Switches

A Dual WAN Console Server can provide tech support personnel with additional options for Out-of-Band Management that aren’t generally available on console server products that include only one Ethernet Port. In addition to allowing remote access to console ports on routers and switches via both a primary, production network and a secondary, maintenance network, a Dual WAN Console server also simplifies the challenge of adding 3G/4G LTE cellular broadband access and satellite broadband access to your out-of-band management solution.

An Out-of-Band Management solution provides IT personnel with an effective means to deal with problems at remote network equipment installations, even when normal network communication is down. By providing alternative channels for communication, an Out-of-Band Management solution allows NOC personnel to troubleshoot problems with remote devices in order to restore communication via the primary network without the costs and delays inevitably associated with a physical service call.

When the Out-of-Band Management solution includes a console server with two Ethernet Ports, (such as WTI’s DSM-E Series Dual WAN Console Servers,) a variety of different communication channels are available to access console port command functions on remote devices. For example, in addition to the dial-up access provided by conventional, single WAN console servers, a Dual WAN Console Server can also allow out-of-band communication via secondary network, 3G/4G/LTE cellular broadband or satellite broadband. This provides a perfect fit for oil and gas industry applications where dial-up, POTS communication is often unavailable.


Remote pipeline support facilities such as compressor stations and metering stations often include networked devices that collect data and monitor conditions at the site. When a Juniper Industrial Ethernet Switch or a router or peripheral network element at a remote pipeline support station becomes unresponsive and disrupts normal network communication with the site, your IT Team needs out-of-band access to console port command functions on critical devices at the site in order to restore network access. Due to the critical nature of these pipeline support facilities, support personnel need two different channels for out-of-band management.

3G/4G/LTE Cellular Broadband Based Out-of-Band Management for Compressor Stations and Metering Stations


Out-of-band access to console port command functions at remote pipeline facilities can be provided by a DSM-NM-E Series Dual WAN Console Server equipped with the 4G LTE Cellular option installed in the remote equipment rack. The presence of two 10/100/1000Base-T Ethernet Ports allows the DSM-NM-E to be connected to both a primary Ethernet cable and a secondary Ethernet cable. The 4G LTE Cellular Option provides an additional channel for out-of-band access via a 4G LTE Cellular WAN Gateway at the NOC. If a malfunctioning switch or router at a metering station or compressor station disrupts normal network communication with the site, NOC personnel can still access console ports at the remote site in order to address router or switch problems and restore network communication without a truck roll or service call.

In addition to allowing remote access to console ports on switches and routers, (such as Juniper’s EX3300 Series Industrial Ethernet Switch,) the DSM-NM-E Dual WAN Console Server can also be connected to other peripheral elements at the site such as leak detection systems and intrusion detection systems in order to provide out-of-band access to console port command functions on those devices too.


Support personnel at your centralized NOC facility can quickly deal with network issues at compression stations and monitoring stations either via normal in-band network access or, (in the event that the network is down,) via out-of-band dial-up wireless broadband or dial-up access. This provides two out-of-band management options for dealing with problems at the remote site and adds a layer of system redundancy, further reducing the likelihood of downtime.

In addition to providing both wireless and dial-up channels for out-of-band access, the DSM-NM-E Dual WAN Console Server with 4G LTE Cellular option also helps your IT team to track suspect conditions and events at remote pipeline facilities. The DSM-NM-E can monitor temperature levels, power supply interruptions, ping command failure and other potential signs of trouble and immediately notify support personnel when any of these factors exceeds user-defined trigger levels. All of these conditions and events can also be recorded to a time-stamped activity log which also tracks user access history and account activities.


WTI’s DSM-NM-E Series Dual WAN Console Servers provide the ideal out-of-band management solution for oil and gas industry applications and other network installations that demand high availability and minimal downtime. The presence of a second 10/100/1000Base-T Ethernet Port increases available out-of-band communication options by allowing the connection of a 3G/4G/LTE Wireless Gateway or Satellite Broadband Hub/Gateway in addition to a traditional network cable.

In addition to providing two 10/100/1000Base-T Ethernet Ports and support for 4G LTE Celluar, the DSM-NM-E Dual WAN Console Server with 4G LTE Cellular Option also includes state-of-the art security and authentication features to ensure that access to sensitive console port functions is well protected from unauthorized access. The DSM-NM-E’s monitoring, alarm and event logging functions enable support personnel to track potentially significant events and conditions at remote sites, allowing your IT team to take a more proactive approach to management and anticipate future troubles rather than simply reacting to problems after they occur.
