Part of Environmental IA Controls - Emergency Power Shut-Off
Associated with IA controls: PEMS-1
A lack of an emergency shut-off switch or a master power switch for electricity to IT equipment
Check an emergency power cut-off (EPO) switch is located near the main IT area entrance. It must be clearly labeled and have a protective cover. This requirement is only for computer centers with large server rooms and/or supporting infrastructure rooms hosting large amounts of network equipment and/or equipment such as chillers, battery backup, transformers, etc. NOTES: In general such an area will be in raised floor space. The requirement should not be applied to purely administrative/office space. Also, this requirement should not be applied to a tactical environment, unless it is clearly an "established" fixed computer facility supporting missions in a Theater of Operations. The standards to be applied to determine applicability in a tactical environment are: 1) The facility containing the computer room has been in operation over 1-year. 2) The facility is "fixed facility" - a hard building made from normal construction materials - wood, steel, brick, stone, mortar, etc.
1. A master power switch or emergency cut-off switch for the IT equipment must be located near the main entrance of the IT area. 2. The emergency switch must be properly labeled. 3. The emergency switch must be protected by a cover to prevent accidental shut-off of the power.
