Versatile Interface Processor (VIP2) in the Cisco 7505, Cisco 7507, Cisco 7507-MX, Cisco 7513, Cisco 7513-MX, and Cisco 7576 routers—and in Cisco 7000 series routers using the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI). The VIP2 supports online insertion and removal (OIR), which allows insertion and removal of a VIP2 without first shutting down the system. Online insertion and removal maximizes router availability by allowing the addition or removal of the VIP2 during system operation
The VIP2 supports LAN and WAN port adapters (PAs), including Fast Ethernet, T1/E1, High-Speed Serial Interface (HSSI), T3/E3, T3/E3 ATM, multichannel T1/E1, multichannel T3/E3, OC-3 ATM, Packet over SONET (POS), and OC-12 ATM. Because the VIP2 port adapters do not support OIR, when removing or inserting a port adapter, the system must be shut down first. The VIP2 must be removed from its interface processor slot before removing or installing a port adapter.
