Provide an alternate power supply for the system that is activated pe-11.02_odp.01 and that is:
(a) Self-contained;
(b) Not reliant on external power generation; and
(c) Capable of maintaining pe-11.02_odp.02 in the event of an extended loss of the primary power source.
The provision of a long-term, self-contained power supply can be satisfied by using one or more generators with sufficient capacity to meet the needs of the organization.
