This enumerated value identifies who owns/controls the policy governing this PSU's equipment definition -- for example whether it is owned locally by this UCS domain or by a centralized policy source such as UCS Central. This distinction matters operationally because a PSU definition whose policy is owned by a central management system can't be edited locally without conflicting with that central policy the next time it syncs, which explains why a local change to this PSU's definition might get silently reverted. A typical value is local, meaning this UCS domain's own UCS Manager owns the policy, versus a domain enrolled in UCS Central.
