Describes the router power management features, including NPU power optimization, dynamic power management, power redundancy protection, on-demand transfer of redundant power modules to the power reservation pool, and the configurable maximum power limit for the router.
This chapter describes the power management features on Cisco 8000 Series Routers and the procedures used to configure power optimization, redundancy, and power limits.
NPU power optimization
Describes the NPU power optimization feature, which lets an operator select a predefined power profile to reduce NPU power consumption based on network requirements.
Dynamic power management
Describes dynamic power management, which allocates router power based on the installed cards and operating modes, reduces the number of required power supply units, and improves overall PSU efficiency.
Power redundancy protection
Describes the power redundancy protection feature, which raises an alarm when the required output power exceeds the total feed redundancy capacity, and explains the single-fault and dual-fault protection modes.
On-demand transfer of redundant power modules to power reservation pool
Describes how Cisco 8800 Modular Routers transfer redundant power supply units to the power reservation pool on demand to meet component requirements.
Ability to set maximum power limit for the router
Describes the power-mgmt configured-power-capacity command.
