Control Enhancements

PE-11 (1) EMERGENCY POWER | LONG-TERM ALTERNATE POWER SUPPLY - MINIMAL OPERATIONAL CAPABILITY
The organization provides a long-term alternate power supply for the information system that is capable of maintaining minimally required operational capability in the event of an extended loss of the primary power source.
Supplemental Guidance: This control enhancement can be satisfied, for example, by the use of a secondary commercial power supply or other external power supply. Long-term alternate power supplies for the information system can be either manually or automatically activated.
PE-11 (2) EMERGENCY POWER | LONG-TERM ALTERNATE POWER SUPPLY - SELF-CONTAINED
The organization provides a long-term alternate power supply for the information system that is:
PE-11 (2)(a)
Self-contained;
PE-11 (2)(b)
Not reliant on external power generation; and
PE-11 (2)(c)
Capable of maintaining [Selection: minimally required operational capability; full operational capability] in the event of an extended loss of the primary power source.
Supplemental Guidance: This control enhancement can be satisfied, for example, by the use of one or more generators with sufficient capacity to meet the needs of the organization. Long-term alternate power supplies for organizational information systems are either manually or automatically activated.
