Emergency Access to Command Functions via Dual Ethernet Console Server

Wednesday, July 30th, 2014

In many cases, the challenge of dealing with a network outage is a fairly simple proposition. Once one has determined which network element has caused the outage, it’s simply a matter of connecting to the console port on the afflicted device and changing a few configuration parameters or running a troubleshooting routine. Unfortunately, in the era of colocation the task of accessing a malfunctioning device can often prove to be a bit more of a challenge if that device is located in a remote data center or locked up safely inside of a distant equipment enclosure. In cases like this, a Dual Ethernet Console Server can provide network administrators with redundant access to remote devices, even when primary network communication is not available.

Dual Ethernet Console Server – Other Options for Remote Access to Vital Network Elements

Friday, July 25th, 2014

A Dual Ethernet Console Server can provide network administrators with a variety of different options for accessing console port command functions on remote or inaccessible network elements. This is especially true if the Dual Ethernet Console Server includes separate routing tables for each Ethernet port. In addition to serving as a vital element in network redundancy applications, a Dual Ethernet Console Server can also simplify remote console access in applications that feature an isolated maintenance network and can also provide additional communication options for server room crash carts.

A Dual Ethernet Console Server Provides More Options for Access to Remote Console Ports

Thursday, October 31st, 2013

In remote network management applications, console servers are used to provide administrators and support personnel with a secure, out-of-band avenue for communication with console ports on distant network elements. Most network engineers are fairly familiar with the basic out-of-band communication functions provided by a console server, but not all realize that a console server with dual Ethernet ports can provide additional communication capabilities beyond basic out-of-band management.

An AB Fallback Switch for Mirrored Network Applications

Thursday, August 22nd, 2013

A well-designed AB Fallback Switch can provide an effective, reliable means to switch back and forth between a primary network path and a secondary network path, without the need to constantly change configuration parameters or reroute IP addresses. Although this capability is very useful in a number of different network applications, it is particularly useful in the case of a mirrored network.

A Dual Ethernet Console Server Provides More Options for Remote Console Access

Wednesday, August 7th, 2013

Console servers provide a vital function for network managers and support personnel, by enabling secure, out-of-band access to console port command functions on remote network elements without the need to travel to the installation site in person. Although this function is absolutely vital for remote network management applications, a console server can also provide other capabilities if the console server includes dual Ethernet ports.

Maximize Up-Time with an A/B Fallback Switch

Monday, November 15th, 2010

It doesn’t matter if you’re talking about a large, multinational corporation or a small “Mom and Pop” business; these days, most businesses depend on a secure, reliable network in order to track sales, process orders and interact with customers. This means that when your network is down, your business is also “down,” because communication and the free flow of information immediately grind to a halt.

How Can an Out of Band Management Solution Minimize Network Downtime?

Monday, September 27th, 2010

These days, most large, corporate networks are actually comprised of two separate networks: one main network that allows users to access emails, inventory programs, servers and so forth, and a secondary “maintenance network” which provides out of band management capabilities, allowing IT personnel to access critical network elements when the main network is down or unavailable. This secondary maintenance network actually has several purposes; it enables IT personnel to upgrade or reconfigure network elements without effecting the ability of network users to access their files and emails, and it also provides the ability to diagnose and correct equipment problems if the main network ceases to function correctly.
