When an uncooperative network device in a remote equipment rack crashes and disrupts network communications, network administrators need a meals to deal with the problem immediately, without waiting for a service team to arrive on site and before users start to complain. In cases like this, a console access server can provide quick, reliable, out-of-band access to configuration and command functions on the remote device without the expenses and delays associated with a physical service call.

When adding an out of band management solution to a collection of existing remote network equipment sites, it’s often surprising to see how many old DB9 based devices are still being used at those sites. Obviously, most of your newer network equipment will feature RJ45 serial ports, but there will always be a smattering of reliable, old legacy devices that are still an important part of your network infrastructure, yet still include DB9 serial ports. In cases like this, sometimes the most immediate solution is to start wiring up adapters to connect those old DB9 devices to your new RJ45 format console access server … but there’s also an easier way that doesn’t involve a confusing web of adapters and cables.
A console access server provides network administrators with a convenient “back door” for out-of-band access to console port command functions on remote network elements. Although this function can prove extremely valuable when troubleshooting communication problems at remote sites, it’s also a good idea to keep in mind that without proper security and authentication features, a console access server can also present a potential weak spot in your network security.
A well-designed, full featured console access server can do a whole lot more than merely provide out of band access to console port command functions on remote network devices. If a console access server includes environmental alarms and event alarms, then it can also help network administrators to keep better tabs on conditions at remote network equipment sites.
In many out of band management applications, the console access server needs to provide different types of access rights to different types of users. For example, some users might need access to all devices that are connected to the console access sever, other users might only need access to one individual network element and others might be restricted to only being able to view the status of specific network elements that belong to their department or job function. In this type of application, where a variety of different users must share the console access server it’s important that the console access server includes a multi-level user directory that allows network administrators to grant different access rights to each user account.
Console Access Server units can perform a number of valuable tasks in a remote network equipment installation. In addition to providing secure, reliable out of band access to console port command functions when the main network is not available, console access servers can also be used to collect error messages and other data, generated by connected network devices.
A Console Access Server with Outbound SSH/Telnet Support Provides More Alternatives for CommunicationTuesday, April 26th, 2011
In out of band management applications that rely on a console access server (http://www.wti.com/c-51-console-access-servers.aspx) for communication with remote network devices, reverse/outbound SSH/Telnet can be an extremely useful feature. In addition to providing a means to communicate with other network devices, outbound SSH/Telnet is also extremely handy in cases where an equipment rack is not connected to your main network, and the only way to communicate with devices in the rack is via dial-up or satellite modem.
Abnormally high or low rack temperatures can often be an indication of potential problems at a network equipment site. If a network equipment rack is located down the hall from your office, then it’s relatively easy to keep track of rack temperatures. But if the equipment rack is located in a remote site, half a world away from your office, then tracking equipment temperatures can present a bit of a challenge. In cases like this, a console access server that includes a temperature alarm feature can often prove to be a valuable asset for network administrators who are responsible for equipment at remote installations.
A console access server provides network administrators with a single interface for management of remote network equipment sites. When a console access server is installed at a remote network site, administrators can use it to access console port command functions on remote devices, create outbound SSH/Telnet connections to other devices, collected error messages and other data from connected devices and monitor and record events and environmental conditions at the remote site. If the console access server also includes environmental alarms or event alarms, network administrators can also be automatically notified when critical conditions or events are detected at the remote network site.
An out of band management solution that includes a console access server allows network administrators to access console port command functions on remote network elements, monitor critical events and environmental conditions at remote sites, and establish outbound SSH connections to other devices at the remote site. If the console access server also supports SNMP control, monitoring and configuration, then this provides network administrators with even more vital tools to simplify the management of remote network equipment sites.
