Network Out-of-Band Management (OOBM)
Concepts

Example

In a typical data center installation, blade switches in a C-class enclosure
connect servers to the data network, while the management port of the OA
module in the C-class enclosure connects the switches to a physically and
logically separate management network. This allows network administrators
to manage the switches even if operation on the data network is disrupted.
In the illustration below, the switches face the hot aisle of the data center,
allowing easy connection to the network ports on the backs of the servers.

For even more control, the serial console ports of the switches could be
connected to the management network through a serial console server (essen­
tially, a networked serial switch), allowing the network administrators to view
the CLI activity of each switch at boot time and to control the switches through
the console ports (as well as through the management ports).
