The Console Server: A Vital Tool for Out-of-Band Management

Monday, October 28th, 2013

In applications that involve communication with remote network elements, reliable out-of-band console access can spell the difference between effective management and chaos. When normal network communication is disrupted by a crashed Ethernet switch or other device at a remote equipment installation, out-of-band access to console port command functions enables administrators to correct the problem without the expenses and delays associated with a physical service call. An intelligently deployed Console Server provides the most effective solution for out-of-band access to remote network elements when normal network communication is not available.

Secure Out-of-Band Management Using a Console Access Server

Tuesday, September 3rd, 2013

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.

A Replacement Console Server Solution for the Cisco 2509

Wednesday, July 31st, 2013

Ever since the Cisco 2509 router/hub was discontinued in 2004, many network engineers have had an increasingly difficult time finding a suitable remote console access solution. Although determined 2509 seekers can occasionally dig up a used 2509 here and there, it’s practically impossible to find enough 2509 units to fit the needs of constantly expanding remote network management applications. If you’ve been hunting for Cisco 2509 units without success, take heart; WTI’s TSM-DPE series console servers can provide the perfect drop-in replacement.

One Console Access Server for Both RJ45 and DB9 Devices

Wednesday, October 19th, 2011

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.

Why Are Security and Authentication So Important for Console Access Servers?

Wednesday, August 17th, 2011

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 Console Access Server with Alarm Features Cuts Expenses and Downtime

Tuesday, June 21st, 2011

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.

A Multi-Level User Directory Can Simplify Console Access Server Management

Tuesday, June 7th, 2011

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.

Using a Console Access Server to Collect Data from Network Devices

Tuesday, May 10th, 2011

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 Communication

Tuesday, 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.

Rack Temperature Alarms Help Console Access Server Units to Keep Tabs on Remote Equipment Sites

Tuesday, April 12th, 2011

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.
