Supplemental Guidance
Organizations determine the types of protection necessary for the power equipment and cabling employed at different locations that are both internal and external to organizational facilities and environments of operation. Types of power equipment and cabling include internal cabling and uninterruptable power sources in offices or data centers, generators and power cabling outside of buildings, and power sources for self-contained components such as satellites, vehicles, and other deployable systems.
Practitioner Notes
Your power equipment and cabling need protection from damage and destruction — whether from accidents, weather, or intentional tampering. Losing power to your systems means losing availability.
Example 1: Route power cabling through conduit or cable trays that protect against physical damage. Place power distribution units (PDUs) and UPS systems in locked areas accessible only to authorized facilities and IT staff. Label all circuits clearly so you know what each one powers.
Example 2: Protect your electrical panel and generator with locked enclosures or rooms. Restrict access to facilities and IT personnel. Include power equipment in your regular maintenance inspections — check for frayed cables, overloaded circuits, and proper grounding quarterly.
