Remote Reboot Units Help Busy Network Administrators to Conserve Valuable Time

Friday, July 29th, 2011

In most cases, network administrators generally have a fairly busy work schedule; their days are already filled with firmware updates, security concerns and responding to user complaints and questions. In a fast paced work environment like this, the last thing that a network administrator needs is a long field trip to deal with an unresponsive network element located at some off-site data center or remote network equipment rack. When a server or router at a remote site fails and disrupts network communication, often the problem can be solved by a simple power reboot, but unless the data center or equipment rack includes a remote reboot unit, that simple power reboot often means a long journey to the equipment site, just to flip a power switch off and back on again.

The Invalid Access Alarm – An Additional Layer of Console Server Security

Thursday, July 14th, 2011

Given the important role that a console server (http://www.wti.com/c-4-console-server.aspx) plays in out of band management, and the powerful command functions that can be accessed using a console server, it’s fairly obvious that security is an extremely important consideration for any console server application. Since a console server provides remote access to console port command functions on important network elements, it’s absolutely vital that the console server includes adequate security and authentication measures to protect sensitive command functions from unauthorized access.

A Terminal Switch Provides a Valuable Tool for Out of Band Management

Monday, June 6th, 2011

The out of band management capabilities provided by a terminal switch can be a real life saver for network administrators who are charged with the task of managing remote network equipment racks. Without a terminal switch, often the only way to deal with problems at remote equipment sites is a costly service call or truck roll to a remote equipment site that might take hours, or even days to reach. Obviously, the remote console port command access provided by a terminal switch can be a real life saver, but the remote monitoring and alarm notification capabilities provided by a full featured terminal switch can be equally helpful too.

Out of Band Management – A Secure, Reliable Way to Deal with Problems at Remote Network Equipment Sites

Monday, May 2nd, 2011

When a network element at a remote installations site malfunctions, the last thing you want to do is send your IT support team off on an expensive, time consuming trip to visit the site in person. Not only are truck rolls and service calls often a waste of time and money, but if your remote network equipment site includes an out of band management solution with adequate security and authentication measures, then a service call is often completely unnecessary.

Monitoring and Alarm Capabilities Increase the Power of an Out of Band Management Solution

Monday, April 18th, 2011

In most out of band management applications, a console server or similar device is used to provide access to command functions on remote network devices. Although this provides network administrators with a powerful tool for dealing with problems at remote sites after something has gone wrong, it sometimes doesn’t address the need to know about potential problems at remote sites before they get to a point where network communication is effected. In order to assist administrators in anticipating problems at remotes sites, it’s helpful if the console server unit at the heart of the out of band management solution includes appropriate alarm and notification features to keep administrators better informed regarding conditions at remote network equipment sites.

An Invalid Access Alarm Provides Console Terminal Server Units with an Additional Layer of Security

Thursday, April 14th, 2011

In any out of band management application, it’s extremely important to make certain that access to the console terminal server unit is adequately protected from unauthorized access. Since the console terminal server provides access to important command functions on remote network elements, it’s absolutely vital that access to the console terminal server is protected by multiple layers of security and authentication features. In addition to security and authentication protocols, it’s also helpful if the console terminal server includes an invalid access alarm, which can notify network administrators when an unauthorized user may be attempting to gain access.

An Invalid Access Alarm Provides an Additional Layer of Security for Console Server Applications

Friday, April 1st, 2011

Given the powerful remote access capabilities that are provided by a console server (http://www.wti.com/c-4-console-server.aspx), it’s absolutely vital that console server products include adequate security measures to protect sensitive command functions from unauthorized access. Typically, a console server product will support standard security features such as password protection and data encryption, as well as popular authentication/validation protocols. These more familiar security precautions provide a substantial level of protection from unauthorized access, but in many cases, it’s also helpful if the console server unit includes an invalid access alarm with automatic port locking capabilities.

An Invalid Access Alarm Provides Much Needed Security for Console Server Applications

Friday, March 18th, 2011

The purpose of a Console Server is to provide out of band access to console port command functions on remote network elements. This capability can be absolutely vital for any network administrator who’s responsible for keeping remote network equipment sites up and running 24/7, but it also prevents somewhat of a challenge, security-wise, due to the same remote command access capabilities that make it such an important tool for out of band management. That’s why it’s important that console server products include a robust assortment of security features, plus features such as an Invalid Access Alarm to keep administrators notified when unauthorized users may be attempting to gain access to sensitive command functions.

Serial Console Servers Simplify Management of Remote Network Equipment Sites

Wednesday, February 23rd, 2011

A serial console server provides network administrators with many valuable capabilities that can help simplify the process of managing remote network equipment and monitoring conditions at remote network installation sites. When paired with a secondary/maintenance network or modem, a serial console server also provides an out of band management solution that allows access to remote network elements when communication via your main network is not an option.

A Serial Console Switch with Alarm Notification via SNMP Trap

Thursday, October 21st, 2010

A serial console switch performs many different duties in a network application; it allows out of band access to network devices when your main network is down, it provides a backdoor to configuration and diagnosis functions without interfering with regular network communication, and it can also monitor network devices for potentially harmful environmental conditions and suspicious network events. Alarm and monitoring functions are an extremely useful capability, but only when the console switch includes a means to effectively notify network administrators when a problem is detected.
