A Server Console Switch with Outbound SSH and Telnet Provides More Communication Alternatives

When implementing an out of band management solution for an offsite data center or remote network equipment rack, it’s best to include as many communication options as possible. The reason for this is simple; if problems with vital network elements at the remote site disrupt normal network communication, then you need an alternative channel of communication in order to be able to access the problematic network device and solve the problem without resorting to a service call. In cases like this, a server console switch with outbound SSH capabilities can provide network administrators with a versatile, alternative means of communication when normal network communication is not available.

When dealing with remote equipment racks and off-site data centers, a server console switch with outbound SSH and Telnet capabilities provides network administrators with a convenient alternative for communicating with remote devices during network outages. When normal network communication is down, administrators can still establish a dial-up connection with the server console switch, and then initiate an outbound SSH or Telnet session to contact vital network elements in order to gain access to command and diagnostic functions. Once a dial-up connection to the server console switch is established, outbound SSH/Telnet enables secure, reliable communication with any device on a LAN at the remote site. These capabilities can prove to be extremely useful in both cases where the main network has crashed, and also in cases where an offsite data center or remote network equipment cabinet is beyond the reach of cable communication with the outside world, yet the remote site still includes a LAN.

When a widespread network outage is caused by a malfunctioning or poorly configured network element at a remote site, a server console switch with outbound SSH/Telnet capabilities often provides the only means to communicate with the device that is the source of the problem without resorting to an expensive, time-consuming service call. Rather than driving out to the site to address the problem in person, administrators and tech support personnel can quickly establish a dial-up connection to a server console switch at the remote site, and then create an outbound SSH or Telnet connection to the device that is causing the problem, and then reinitialize the device or change configuration parameters to quickly restore network communication.

In other cases, where the physical location of remote network equipment makes a direct network cable connection impractical, outbound SSH and Telnet capabilities can serve as a practical means for routine communication with devices at the remote site. When the remote network equipment installation includes a server console switch that supports outbound SSH and Telnet, administrators can easily dial in to the server console switch, and then employ outbound SSH/Telnet to connect to any IP address on the LAN at the remote equipment site. This type of application provides an economical means to communicate with vital network elements at the remote site, without the expense of running a network cable all the way out to the middle of nowhere.

By design, an out of band management solution is supposed to provide administrators with a means to communicate with remote network devices when normal communication is not possible. Some times, this capability is used to deal with network emergencies that have made normal communication impossible, and other times the out of band management solution provides the only workable means for communication with devices that are so far off the beaten track that a normal network connection is not feasible. A server console switch with outbound SSH and Telnet capability provides valuable out of band communication tools that can come in extremely handy in either of these cases.
