The VIP4 supports online insertion and removal (OIR), which allows you to remove and replace a VIP4 without first shutting down the system. Online insertion and removal maximizes router availability by letting you add or remove VIP4s during system operation. See the "Guidelines for VIP4 Removal and Installation" section for more information on removing and installing the VIP4.
The VIP4 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. For a list of supported port adapters, refer to the "VIP4 and Port Adapter Compatibility" section.
The VIP4 port adapters do not support OIR, so when removing or inserting a port adapter, the system must be shut down first. The VIP42 must be removed from its interface processor slot before removing or installing a port adapter.
