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 [...]
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 [...]
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 [...]
When managing remote network devices located in offsite equipment cabinets, it’s always best to have as many options for communication with those remote devices as possible; in fact, the more options the better. When normal network communication is either unavailable or impractical, a Linux powered console server should be able provide several different alternatives for [...]
Network administrators who are charged with the task of managing off-site data centers and network elements in remote equipment racks know the value of an effective out of band management solution. When problems at remote network equipment sites disrupt normal network communication, an out of band management solution often provides the only means to remedy [...]
When designing a remote network equipment site or off-site data center, it’s always important to ensure that IT support personnel in your central office have an avenue for out of band management of network elements at the remote equipment site. An out of band management solution ensures that even when your main network is down, [...]
Often, the remote nature of a network equipment site makes it impossible to connect a network cable directly to the remote site. Although the remote network equipment site might include a LAN which allows communication between the devices at the site, outside users such as network administrators back at company headquarters, aren’t able to directly [...]
In out of band management applications that rely on a console access server (http://www.wti.com/c-51-console-access-servers.aspx) for communication with remote network devices, reverse/outbound SSH/Telnet can be an extremely useful feature. In addition to providing a means to communicate with other network devices, outbound SSH/Telnet is also extremely handy in cases where an equipment rack is not connected [...]
A full featured terminal switch unit (http://www.wti.com/c-56-terminal-switch.aspx) can often do a lot more than simply provide access to remote network elements when your main network is down. For example, if a terminal switch unit includes outbound SSH/Telnet capability, this allows administrators to create a dial-up connection with a remote terminal switch unit, and establish an [...]
A server console switch that supports outbound SSH connections allows network administrators to establish secure out of band connections with remote network elements, and provides an ideal tool for communicating with remote devices in situations where normal network communication is not available. This can prove particularly helpful, both in cases where a secondary/maintenance network is [...]
