Using a Dual Ethernet Console Server to Provide Console Access for Maintenance Network Applications

Monday, August 4th, 2014

In large network installations, tech support personnel often find it useful to have an isolated maintenance network, reserved for use as an exclusive avenue to upgrade firmware, perform routine diagnostic functions and deal with network emergencies that may have disrupted access via the primary, user network. When a Dual Ethernet Console Server is included in the maintenance network, this provides both tech support personnel and rank-and-file users with a means to access console port command functions on various network elements.


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

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.


Out of Band Management – An Alternative Avenue for Communication with Remote Devices

Tuesday, July 12th, 2011

One of the most difficult aspects of managing remote network devices is the challenge of communicating with remote network elements when normal network communication is either down or unavailable. When a vital network element at a remote equipment rack crashes and takes network communication down with it, sometimes the only means to address the problem is an expensive service call to the remote site in order to deal with the problem in person. In cases like this, an out of band management unit can provide network administrators with a convenient, reliable means to communicate with remote network elements regardless of whether communication via the main network is viable or not.


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.


Console Terminal Servers are the Heart of an Effective Out of Band Management Solution

Not too many years ago, most networks didn’t include an out of band management solution. That meant that if a firewall crashed or a switch froze and brought the network down with it, then there was no way to use the network to access the stricken network device in order to diagnose and troubleshoot the problem. In this case, the only way to fix the problem was often to travel to a remote network equipment site, access a local console port and start invoking commands until the problem was understood and remedied.


Out of Band Management – An Essential Tool for Network Administrators

Wednesday, October 20th, 2010

To network administrators, the term “out of band management” can mean a number of different things, in some cases, it refers to a secondary, maintenance network that parallels the main network, and in other cases, it may refer to a dial-up/phone line connection to network devices. Generally speaking though, out of band management refers to a connection to a network device that comes from outside of the main user network.


How Out of Band Management Can Make a Network Administrator’s Job Easier

Most modern data centers actually include two separate networks; a main network and a secondary, maintenance network. Typically, the main network allows users to access files and communicate with other users, while the secondary maintenance network is used for out of band management, troubleshooting and testing.


Out of Band Management in a Remote Data Center

Monday, October 4th, 2010

In the past, most remote data centers depended on a single network for communication with the outside world. This worked quite well as long as the network was up and running, but if the network was down, then often there was no alternative means for network administrators to communicate with network elements in order to correct problems; the only way to communicate with a network device was to travel to the installation site and address the problem in person.


Why is Out of Band Management So Important to IT Personnel?

Friday, September 24th, 2010

These days, whenever the subject of remote network administration comes up, you’ll often hear the phrase “out of band” used. Most people have a vague idea that “out of band” refers to an alternative means to establish a remote connection with a piece of network equipment, outside of normal network communication. But just what exactly does the term “out of band” mean?
