The Console Server: An Important Element in an Effective Out-of-Band Management Solution

Friday, September 13th, 2013

When a vital network element located at a remote installation site crashes or becomes unresponsive, an out-of-band management solution can help administrators to correct the problem without the hassles, expense and delays of a service call. When an out-of-band management solution includes a console server, this enables administrators to access console port command functions on remote network elements in order to perform diagnostic routines, change configuration parameters and check conditions at the distant network site without the need to travel to the site in person.

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.

Managing Network Elements at Wind Farms via 3G-4G Modem

Thursday, August 29th, 2013

Most wind farms include a surprising assortment of network devices that are used to control turbine positioning, track wind speed and direction and ensure security at the remote site. When network problems at a wind farm make normal network communication impossible, an out-of-band management solution is required to enable administrators to restore communication without the delays, hassle and expense of a physical service call to the remote wind farm. Given the remote nature of most wind farms, access via 3G/4G modem is often the only viable option for out-of-band communication with network elements in wind farm applications.

Reboot Remote Network Elements with a Power Reboot Switch

Tuesday, August 27th, 2013

When a router or switch at a remote network equipment site crashes or becomes unresponsive, in many cases, all it takes to fix the problem is a simple power reboot. While this is a simple proposition if the network element is located in the office next door, it can be quite a dilemma if the unresponsive network element is located miles away from the office, and even more so if the problematic device makes normal network communication impossible. In cases like this a Power Reboot Switch provides a reliable, easy way to reboot network elements at remote equipment sites.

Out-of-band Management via Cellular Broadband

Tuesday, July 2nd, 2013

Implementing an out-of-band management solution is generally a fairly simple proposition … as long as a network cable or land line is available. But in applications where neither a direct network cable or phone line are present, it often takes a little bit of creativity to put together a workable out-of-band management solution. In cases like this, a 3G/4G modem based cellular broadband solution can often serve as a reliable means for out-of-band access to remote network devices.

Using SNMP to Manage and Control Remote Power Switching and Reboot Functions

Monday, May 21st, 2012

The task of managing network equipment located at remote branch offices presents an entirely different set of challenges than are normally encountered in general network management applications. For one thing, the ability to monitor conditions and events at the remote branch office is typically much more critical than it would be in an application where a local administrator is available to keep an eye on power supplies, phone lines and other factors in person. For another thing, branch office management often requires a degree of conformity between the various branch office sites on the corporate network; user access rights and passwords need to be the same at each site, and similar devices at each branch office must also be similarly configured.

A Console Switch with Outbound SSH and Outbound Telnet Capabilities

Wednesday, January 18th, 2012

When your primary means of communication with remote network equipment fails, it’s always good to have other options for contacting various devices in the remote network equipment rack. As long as you can communicate with the devices in the remote equipment rack, then you still have a chance of solving the communication problem without an expensive service call to the remote rack. Although a console switch provides the basis of an excellent out of band management solution, it can also be helpful if the console switch provides additional communication options that can be employed to communicate with other devices in the remote network equipment rack when your primary network is down or unavailable.

An Out of Band Management Solution for DC Powered Equipment Racks

Friday, January 13th, 2012

When a vital network device at a remote network equipment site malfunctions or refuses to communicate, an out of band management solution provides administrators with a handy way to diagnose and correct problems at the remote site without the expense and inconvenience of a time-consuming service call. As a general rule, the more distant, remote and out-of-the-way the network equipment cabinet is, the more important it is to have out of band access to console port command functions when problems arise at the remote site.

Additional Security for Dial-Up, Out-of-Band Access to Console Servers

Monday, January 9th, 2012

Although there are plenty of different security and authentication options available for IP communication with a console server, security and authentication options are much more limited for those who need to establish a dial-up out-of-band connection with a console server. Popular authentication protocols such as LDAP, Kerberos and TACACS+ work fine when communicating via IP, but at present, there are few alternatives for authenticating dial-up out-of-band communication.
