The new Cascaded Ports feature in Opengear’s IM4200 and CM4000 console servers enables administrators to cluster console servers.
They now can configure and access up to 1000 serial port devices using the one IP address and manage them through the one web UI.
One console server (the Master) controls all the other console servers as Slave units and all the serial ports on the Slave units appear as if they are connected to the Master.
Opengear’s clustering interconnects the Slaves to the Master with encrypted SSH. It then uses public key authentication, so the Master accesses each Slave using a public and private key pair rather than using passwords.
This ensures secure authenticated communications between Master and Slaves, enabling the Slave console server units to be distributed locally on a LAN or remotely around the world.
The new Cascaded Ports solution is being used by a local Telco to manage many hundreds of their serial console devices.
