CIP2 Microcode Guidelines

CIP2 Microcode Upgrade Overview

Following is an overview of what you need to do to upgrade unbundled CIP2 microcode (that

shipped on ﬂoppy diskettes and Flash memory cards) for the Cisco 7000 series and Cisco 7500 series

routers.

Caution To prevent system problems in the following procedure, a CIP2-compatible,

bootloader-capable Cisco IOS image must be booted before the CIP2 microcode image is copied to

Flash memory.

Upgrading from Floppy Diskettes

For CIP2 microcode images that shipped on ﬂoppy diskettes or were obtained from CCO, do the

following:

Step 1 Upload the CIP2 microcode image (and the Cisco IOS image if not on ROMs) on ﬂoppy

diskettes or from CCO to a TFTP server.

Step 2 Remove any conﬁguration commands that specify a CIP2 microcode image from the

running conﬁguration.

Step 3 Save your running conﬁguration to a TFTP server or Flash memory.

Note If you have a Cisco 7000 series router and plan to install new software ROMs with Cisco IOS

Release 11.1 or later, skip Steps 4 and 5 and turn off power to your router.

Install the new ROMs, then proceed to Step 6.

Step 4 Download the Cisco IOS image to Flash memory.

Step 5 Conﬁgure the router to boot from the Flash memory where the Cisco IOS image resides.

Step 6 Boot the Cisco IOS image.

Note The router must already be running a CIP2-compatible Cisco IOS image before performing

a copy of the CIP2 microcode image to Flash memory in the following step, because the CIP2

microcode image must be “exploded” from the single image ﬁle on the TFTP server to multiple ﬁles

in Flash memory. This capability is available in Cisco IOS Release 11.1 or later.

Step 7 Download the CIP2 microcode image to the Flash memory card in slot 0.

Step 8 Restore the running conﬁguration with the conﬁguration you saved to the TFTP server in

Step 3.

Step 9 Reconﬁgure the router, as required, to use the CIP2 microcode image stored in the Flash

memory card in slot 0.

Step 10 Perform a microcode reload.
