The online insertion and removal (OIR) operation lets you replace faulty data and voice modules without affecting system operations. The OIR is similar to hot-swapping. OIR commands are issued before removing and after installing a module. When performing OIR, use an identical module to replace an original one. The difference between hot-swapping and OIR is that OIR requires executing Cisco IOS commands before and after the OIR. Hot-swapping is strictly a hardware function and does not require the execution commands. Not all router components or modules use OIR, or can be hot swapped. The following components use OIR in the routers: • Service Modules (SMs) • Network Interface Modules (NIMs) • Small Form-Factor Pluggable (SFPs) • USB devices The following components can be hot swapped: • Fan tray • Power supply: only when the router is backed up with an optional PSU #Hot_Plugging #Hot_Swapping #online_insertion_and_removal #OIR #Hot_Plug_module #Switch #Router #Cisco @ciscoAcademy

Hot plug is the addition of a component to a running computer system without significant interruption to the operation of the system. Hot plugging a device does not require a restart of the system. Common examples of hot-pluggable devices include a hard disk drive (HDD) or a solid-state drive (SSD) that can be added to a storage system and a USB drive, mouse, keyboard or printer that can be added to a personal computer (PC) and a module that can be added to a switch or network devices. Hot plugging is not the same as hot swapping a component into a running computer system. Hot swapping involves the replacement of a component, whereas hot plugging is the addition of a component that serves to expand the system. #Hot_Plugging #Hot_Swapping #Hot_Plug_module #Switch #Router @ciscoAcademy
