A device may be deliberately placed offline in the LDAP database to indicate that it is unavailable and will remain unavailable for an extended period of time. This may be utilized during system installation so that pre-configured systems can be marked as offline until the system installation is complete. It can also be used for systems that are down for extended maintenance or upgrades. It may be useful for equipment that is on mobile vans and only present for certain days.

For this purpose a separate Installed Attribute has been given to devices, Network AEs, and Network Connections so that it can be manually managed.
