Out-of-Band Management
OOB
Out-of-band management uses a management controller or management path separate from the main operating system's execution path.

In context
It may use a separate physical port or a shared port, so physical independence must be checked in the configuration. Dependencies on server power and the management network also remain.
Example
Even if a hypothetical BMC uses a separate port, remote access may be unavailable if that switch loses power.
Key distinction
Independence from the operating system does not mean independence from every infrastructure failure.
