Console Servers Make It Easier to Deal with Problems at Remote Network Equipment Racks

Friday, June 10th, 2011

When a minor problem with network element brings down your main network, often all it takes to correct the situation is a few diagnostic and troubleshooting commands issued via the console port on the device that caused the problem. If the troublesome network element is located nearby, then it’s no problem to simply walk over to the device, connect to a console port and start issuing commands, but if the device that brought the network down is located miles away, then even a minor problem can halt network communication for hours while a service team travels to the remote site to deal with the problem in person. The best way to avoid network shutdowns caused by minor flukes at remote network equipment sites, is to implement an out of band management solution that includes a console server unit at the remote site.

An Out of Band Management Solution Based on a Server Console Switch

Friday, May 6th, 2011

The task of keeping remote network equipment up and running at all times can sometimes prove to be quite a challenge. When a firewall or a server at a remote network equipment site decides to crash, right when you need it the most, network administrators need to have a back-up plan to get those troublesome devices back on line again, without waiting for a service team to travel to the remote site. In cases like this, a server console switch provides the quickest and most economical means for out of band management; allowing administrators to diagnose and troubleshoot remote network devices without the need for a long, expensive service call to a network equipment rack located two states away.

A Serial Console Server with Power Fallback Capabilities Improves Out of Band Management

Wednesday, April 20th, 2011

In an out of band management application, a serial console server (http://www.wti.com/c-48-serial-console-servers.aspx) performs an extremely critical function; serial console severs provide out of band access to console port command functions on remote network elements. Given the importance of this function, it’s mandatory that the serial console server is up, running and ready to use when you need it. With this in mind, it’s absolutely vital to choose a serial console server that provides dual power inlets and power fallback capabilities in order to ensure that a minor power outage will not deprive administrators of out of band access to crucial network elements in the event of a network outage.

A Console Server Management Unit with a Multi-Level User Directory Provides Unique Capabilities to Each User

Wednesday, April 13th, 2011

Sometimes, a console server management unit can almost be too useful for its own good. In many cases, once network administrators have installed a console server management unit as a part of an out of band management solution, other network professionals within the organization will discover that they could use out of band access to remote network elements too. A typical console server management unit can easily handle the extra user load, but then administrators are faced with the problem of restricting these additional users to appropriate devices and command capabilities. The most practical solution to this problem, is to choose a console server management unit that includes a multi-level user’s directory.

Power Fallback – A Vital Capability for Remote Console Servers in Mission Critical Applications

Tuesday, April 5th, 2011

Most network administrators who are responsible for the management remote network equipment sites are already familiar with the value and convenience of a remote console server. Considering the importance of the out of band management capabilities that are provided by a remote console server, it makes perfect sense to ensure that the remote console server is always ready to use when it’s needed the most. One way to improve the reliability of an out of band management solution, is to make certain to choose a remote console server unit that includes dual power inlets and power fallback capabilities.

Out of Band Management Units for Both DB9 and RJ45 Environments

Monday, April 4th, 2011

Adding an out of band management solution to an existing remote network equipment installation doesn’t necessarily mean that you need to re-cable an entire equipment rack in order to provide compatibility with a newer out of band management unit. In order to simplify the process of adding out of band management capabilities to an existing network application that uses older DB9 format cables, some modern out of band management products are available in both DB9 and RJ45 format.

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.

A Console Terminal Server with Event Logging Improves Remote Network Management

Thursday, March 31st, 2011

In many remote network management applications, a console terminal server does more than merely providing remote access to console port command functions. Often, the console terminal server also helps network administrators to keep better track of events and conditions at remote sites without the need to constantly send technicians out to check on the site in person. In addition to providing out of band access to remote network elements, a console terminal server can also monitor and log power interruptions, user activity, temperature trends, alarm events and other significant data concerning a remote network site that can help to give administrators a broader perspective of conditions and trends at a remote site in order to assist in planning for future needs and contingencies.

Why is a Ping Response Monitor an Important Element for Console Server Management Solutions?

Wednesday, March 30th, 2011

In most out of band management applications, a console server management unit is employed to provide remote access to console ports on critical network devices. This provides network administrators with a valuable tool for invoking diagnostic, troubleshooting and configuration commands at remote devices without actually traveling to the remote equipment site in person. Out of band access enables administrators to respond more quickly to network emergencies and reduces network downtime, but if the console server management product also includes a ping response monitor (or ping-no-answer alarm) then the console server unit can also automatically alert administrators whenever a target device fails to respond to ping commands.

Why a Multi-Layered Approach to Security is Vital for Terminal Switch Applications

Monday, March 28th, 2011

Given the powerful remote access capabilities that a terminal switch (http://www.wti.com/c-56-terminal-switch.aspx) provides in an out of band management application, it’s absolutely vital to ensure that a terminal switch includes adequate security features to protect critical console port command functions from unauthorized access. Almost all terminal switch units include basic security features such as password protection, but in many terminal switch applications, simple password security isn’t enough; that’s why it’s important to select a terminal server product that supports additional, advanced security functions functions such as authentication and encryption such as HTTPS and the ability to create SSL security certificates.
