A Console Switch with Outbound SSH and Outbound Telnet Capabilities

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.

One console switch capability that can come in particularly handy when dealing with communication problems at remote equipment racks, is the ability to establish an outbound Telnet or outbound SSH connection with other devices in the rack. When the console switch supports outbound SSH/Telnet connections this enables network administrators to establish a connection with the console switch via dial-up or secondary network, and then employ the outbound SSH/Telnet feature to create a connection to any other device on the local area network at the remote equipment rack; regardless of whether the target device is cable-connected to the console switch or not.

In addition to providing command access to other devices in the remote rack when normal communication crashes, a console switch with outbound SSH/Telnet capability can also provide an ideal out of band management solution for remote network equipment applications where a direct network connection to the remote network equipment rack is not practical or feasible. In cases where off-site data centers or remote equipment racks are located so far off the beaten track that running a network cable to the remote site would not be economical, network administrators and tech support personnel can still use the outbound SSH/Telnet feature to establish a network connection to devices at the remote site. In cases like this, rather than providing emergency communication with the remote site, a dial-up connection would be used to conduct all routine communication with the remote site, and the outbound SSH/Telnet feature would then be employed to communicate with various other devices at the remote network equipment site.

When managing vital network elements located in distant equipment racks, a console switch that provides outbound SSH/Telnet communication can be an extremely useful asset for both network administrators and tech support personnel. In emergency situations, a console switch with outbound SSH/Telnet capability enables administrators and support personnel to create a secure IP connection to any device on the local area network at the remote site; even when the device in connection is not directly cable-connected to the console switch. In normal, non-emergency situations, a console switch with outbound SSH/Telnet capability can provide a secure means to access console port command functions on any device on the local area network at the remote site, even when normal network communication is not an option.
