Out-of-band management is especially suited to situations when no other server access is
available. It can be invaluable in emergency situations to return a server with a non-responding
operating system to service until it can be managed again with in-band tools. Out-of-band
management is less secure because it depends on the configurations of the other out-of-band
components in the mix.
Telnet or SSH are used to manage the devices. Network ports are not used for device
management. A separate network is maintained for management access and control data.
