A Serial Console Server that Supports Data Buffering

Thursday, June 30th, 2011

In many remote network equipment rack applications, the serial console server is mainly used to provide out of band management access to console port command functions on vital network elements. Although out of band management capabilities are absolutely vital for the efficient management of remote network devices, a serial console server can also be called on to perform other tasks that can be equally helpful to network administrators. For example, a serial console server that includes buffer mode ports can also be used to collect error messages and other data from connected network elements.

In many applications, a console server management unit needs to be able to perform multiple functions at the same time. It’s pretty much a given that a console server management unit will need to provide out of band access to remote network devices, but in addition to that important function it might also need to be able to monitor rack temperature, check devices for ping response and capture error and status messages that connected devices send out via console port.

Different Serial Port Modes for Different Remote Console Server Port Applications

Tuesday, June 14th, 2011

In many applications, a remote console server needs to be able to perform other tasks besides providing out of band management access to console ports on remote network devices. In a remote network equipment rack, it’s pretty common to see a remote console server that’s not only being used for out of band access, but also to collect status and error messages from attached devices or to provide access to an external modem in the equipment rack. In situations like this, it’s extremely helpful to have a remote console server that includes the ability to redefine serial ports for specialized tasks.

Serial Port Modes Simplify the Task of Installing a Serial Console Server

Wednesday, May 18th, 2011

In out of band management applications, it’s not surprising to see a serial console server connected to a wide variety of different devices that are accessible to a wide variety of different users and functions. Some ports on the serial console server might be used for modem communication, other ports might be used for data collection, others might need to allow access to serial console server command mode functions and others might need to deny access to command mode functions. For this reason, a well-designed serial console server will often include the ability to assign each serial port to a specific port mode in order to simplify the process of configuring ports for different functions and needs.

In the early 2000s, when Console Server products first started to gain popularity, most console servers were used only by Network Administrators, who needed out of band management capabilities for remote network equipment sites. But as the capabilities of console servers grew, the need arose to dedicate specific console server ports to specific types of functions. One way to control the functions of console sever ports, was to assign specific “modes” to each available serial port.
