VIP-FE-TX Installation and Configuration 11

Versatile Interface Processor Functions

Note VIP-FE-TX is a ﬁxed conﬁguration. The FE-TX port adapter is not available as a spare part.

The entire VIP-FE-TX assembly is a FRU. The FE-TX port adapter has a handle attached, but this

handle is not shown to allow a full view of the detail on the 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.

When only one port adapter is installed on a VIP, as with the VIP-FE-TX, a blank port adapter must

ﬁll the empty slot to allow the VIP and router chassis to conform to electromagnetic interference

(EMI) emissions requirements, and so that air ﬂows through the chassis properly. The blank port

adapter is shown in Figure 8.

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-conﬁg EXEC

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 24.
