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.

When managing network devices located at off-site data centers or in remote equipment cabinets, it isn’t always easy to tell when power to the remote network equipment has been interrupted and restored. Sure, you could always wait for users to complain that a server or router at the remote site didn’t recover correctly, but in a busy corporate network environment a network administrator often needs to be more proactive when it comes to dealing with power interruptions and disrupted network service. It’s pretty easy to tell when power at the remote network equipment site is out completely, but how does one recognize a situation where power momentarily blinks off and then back on again?
Outbound SSH/Telnet Provides Another Alternative for Console Switch Communication with Remote Network DevicesWednesday, November 23rd, 2011
Most network administrators are already familiar with the concept of using a console switch to create an out of band connection to network elements at a remote equipment site, but it might come as a surprise to some that a console switch can also be used to provide out of band access to a local network at a remote equipment site. When network equipment cabinets are located so far off the beaten track that direct network communication with the cabinet is not possible, a console switch that supports outbound SSH/Telnet can be employed to allow users to access a local network at the remote site via dial-up connection, and then communicate with any device on the local network at the remote site.
