Cisco ASR 9000 Series Router modular line cards (MLCs) and modular port adapters (MPAs) support online
insertion and removal (OIR). Modular port adapters (MPAs) can be inserted or removed independently from
the MLC. OIR of a MLC with installed modular port adapters (MPAs) is also supported.
Caution
Cisco IOS XR Software 6.6.1 and later releases support online insertion and removal (OIR) of Cisco NCS
5500 series modular port adapters (MPAs).

rack/slot/subslot shutdown, and no hw-module subslot rack/slot/subslot shutdown commands to
complete online insertion and removal. Refer to the Hardware Redundancy and Node Administration
