Versatile Interface Processor Functions
Note The VIP-FE-TX/4E is a fixed configuration. The FE-TX and 4E port adapters are not available as individual spare parts. The entire VIP-FE-TX/4E assembly is a FRU. The FE-TX and 4E port adapters have a handle attached, but this handle is not shown to allow a full view of detail on each port adapter’s faceplate.
Caution To prevent system problems, do not remove port adapters from the VIP motherboard or attempt to install other port adapters on the VIP motherboard.
VIP Microcode Overview
The VIP microcode (firmware) is an image that provides card-specific software instructions. A Flash memory device in socket U17 of the VIP contains the default microcode boot image. The router supports downloadable microcode, which enables you to upgrade microcode versions by downloading new microcode images, storing them in system Flash memory, and instructing the system to load its image from Flash instead of the default VIP image. (The RP in the Cisco 7000 and 7010 loads software from ROM or Flash memory; the RSP loads software from Flash only.) You can store multiple images for an interface type and, with a configuration command, instruct the system to load any one of them or the default ROM image. All interfaces of the same type (VIP, and so on) will load the same microcode image, either from the default ROM image or from a single image stored in system Flash. Although multiple microcode versions for a specific interface type can be stored concurrently in Flash, only one image can load at startup. The show controllers cbus command displays the currently loaded and running microcode version for the SP or SSP (in the Cisco 7000 series routers), each interface processor, and VIP. The show startup-configEXEC command shows the current system instructions for loading microcode at startup.
Software and interface processor microcode images are carefully optimized and bundled to work together. Overriding the bundle can result in system incompatibilities. We recommend that you use the microcode included in the software bundle. For a complete description of microcode and downloading procedures, refer to the section “Upgrading VIP Microcode” on page 23.
VIP Installation Prerequisites
This section provides a list of parts and tools you will need to perform the installation, and it also includes safety and ESD-prevention guidelines to help you avoid injury and damage to the equipment. This section also provides a detailed description of the OIR function to help you perform online installation successfully and avoid error message and system restarts. If you are installing a new VIP, be sure to review the equipment descriptions and distance limitations in the section “FE-TX Port Adapter Receptacles, Cables, and Pinouts” on page 33 when preparing your site and planning network connections.
