A classic example of this limitation is when a sysadmin attempts to reconfigure the network on a remote machine only to find themselves locked out and unable to fix the problem without physically going to the machine. It does not allow management of remote network components independently of the current status of other network components.
#Lights out management software
It typically requires software that must be installed on the remote system being managed and only works after the operating system has been booted and networking is brought up. It allows a system administrator to monitor and manage servers and other network-attached equipment by remote control regardless of whether the machine is powered on or whether an OS is installed or functional.īy contrast, in-band management through VNC or SSH is based on in-band connectivity (the usual network channel). In computing, one form of out-of-band management is sometimes called lights-out management ( LOM) and involves the use of a dedicated management channel for device maintenance.
It also can be used to ensure management connectivity (including the ability to determine the status of any network component) independent of the status of other in-band network components. Out-of-band management allows the network operator to establish trust boundaries in accessing the management function to apply it to network resources. Out-of-band management is now considered an essential network component to ensure business continuity. Cellular 4G and 5G networks are used today for out-of-band management and many manufacturers have it as a product offering. Out-of-band ( OOB) management is a networking term which refers to accessing and managing network infrastructure at remote locations, and doing it through a separate management plane from the production network.

In systems management, out-of-band management involves the use of management interfaces (or serial ports) for managing networking equipment.
