Check there is an IT area voltage control unit and that it is being utilized for all key IT assets. NOTES: This requirement should not be applied to a tactical environment, unless it is a fixed computer facility supporting missions in a Theater of Operations. The standards to be applied for applicability in a tactical environment are: 1) The facility containing the computer room has been in operation over one year. 2) The facility is "fixed facility" - a hard building made from normal construction materials - wood, steel, brick, stone, mortar, etc.
An Information Technology (IT) area voltage control unit must be installed and used for all key IT assets.
