SNMP MIB Compatibility and Console Server Management

When choosing a console server management solution, it’s vital to ensure that your solution provides compatibility with third party software products such as Openview or Solaris. The reason for this is because these products provide network administrators with a centralized point of access from which they can manage many different network devices scattered across multiple [...]

Maximize Up-Time with an A/B Fallback Switch

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 [...]

How a Serial Switch with Buffered Ports Helps to Cut Network Downtime

In addition to providing out of band access to network devices, a well designed serial switch should also be able to collect data from connected devices, and then later allow you to retrieve that data in order to check device status and operation. When a serial switch includes buffered ports, data such as error messages, [...]

An SNMP Enabled Console Server – Centralized Management for Remote Network Sites

Large, modern, corporate networks often include dozens of remote network equipment sites. Sometimes, these remote sites are located several states away; other times, they might be located on the other side of the Earth. With this in mind, it quickly becomes obvious that in order to maintain such a network, it’s vital for the network [...]

Different Command Interfaces for Different Console Server Users

Once a console server has been installed and configured, in most cases you won’t need to communicate with it very often at all. But when you do need to communicate with a console server, it’s nice to know that you have several different options for accessing command functions and aren’t limited to just one command [...]

A Console Server with Outbound SSH and Telnet

Troubleshooting problems at remote network equipment sites can sometimes be frustrating, especially when the source of the problem is a malfunctioning firewall. When the firewall is down, that often means that you can’t contact any of the network devices behind the firewall in order to remedy the problem, but that doesn’t necessarily mean that you [...]

A DC Powered Console Server Can Go Places Where AC Power is Impractical

All remote network equipment applications can benefit from the secure console port access that’s provided by a console server. Unfortunately though, most console servers run on AC power, and if that network equipment is located at a remote site, or in other locations where only DC Power is available, then the only practical solution is [...]

A Console Server that Lets You Know When your Equipment Rack is too Hot or too Cold

In addition to allowing secure access to console port functions on remote network devices, a good console server should also be able to keep network administrators informed when environmental conditions inside of the rack could potentially impede the performance of network devices. For example, if rack temperature rises too high or falls too low, this [...]

A Simple Way to Manage Console Server Access Rights for Multiple Users

A console server can be an extremely handy tool for remote network administration; sometimes, it can be almost too handy. Access rights usually aren’t a problem when only your IT support staff have access to your console server, but often, once other departments discover what can be done with a console server, they’ll suddenly need [...]

Outbound SSH/Telnet – Another Alternative for Connecting to Remote Network Devices
