Describes the operational behavior of hardware modules on Cisco 8000 Series Routers, including Modular Port Adapter reload, online insertion and removal guidelines for optics on Cisco 8000 Series Routers, and compatibility behavior for line cards based on different NPU types.
This chapter describes the hardware modules supported on Cisco 8000 Series Routers and the compatibility behavior between line cards that use different Network Processing Unit (NPU) types.
Compatibility mode for various NPU types
Explains the compatibility mode that allows line cards based on different NPU types to coexist on the same Cisco 8000 series router, and details the resulting boot and operational behavior for each scenario.
MPA reload
Describes how the data path power-on timer manages Modular Port Adapter initialization on Cisco 8000 series routers and triggers an automatic reload when an MPA does not come up within 20 minutes.
Online insertion and removal on Cisco 8700 Series routers
Provides Online Insertion and Removal guidelines for optical modules on Cisco 8700 Series routers.
