What happens during an Online Insertion and Removal (OIR)?

A. When you insert the second-generation Versatile Interface Processor (VIP2), power is available on the VIP. The VIP initializes to get ready to download the VIP kernel code. In the meantime, the VIP has powered up the Port Adapter (PA), which goes through some initialization steps to prepare the hardware. The VIP kernel is downloaded, and the VIP discovers what PAs are present. The VIP then sizes the SRAM and DRAM memory, and communicates with the Route/Switch Processor (RSP) as to what has to be done to the PA hardware to make the PA hardware fully functional.
