Check Content

Check an emergency power cut-off (EPO) switch is located inside the IT room or area near the main entrance/exit. 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, a server/computer room will have raised floor space and air conditioning and host multiple servers. 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 more than one year. 2. The facility is "fixed facility" - a hard building made from normal construction materials (wood, steel, brick, stone, mortar, etc.).

Fix Text

1. A master power switch or emergency cut-off switch for the IT equipment must be located inside the IT area near the main entrance. 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.
