Introduction

This document describes Cisco's recommended process for successful MGX 8220 Edge Concentrator bootcode and firmware upgrades and downgrades. AXIS is the legacy product name for the Cisco MGX 8220 Edge Concentrator.

The following upgrade and downgrade techniques for the AXIS Shelf Controller (ASC) and Service Module (SM) are provided.

• Graceful Upgrades

• Ungraceful Upgrades

• Downgrades

Refer to Concepts and Definitions for additional information.

Prerequisites

Requirements

Use of the procedures discussed in this document assumes that you have a working knowledge of the MGX 8220 Edge Concentrator. We recommend that you read both documents completely before proceeding with a firmware upgrade.

Components Used

MGX 8220 upgrades to firmware version 5.0.x are supported only for versions:

• 4.0.x

• 4.1.x

• 5.0.x

For upgrades from version 2.x or 3.x, you must first upgrade devices to the latest generally available firmware version of 4.0.x or 4.1.x and then upgrade them to version 5.0.x. Special considerations apply when upgrading:

• From versions 2.x and 3.x

• Inverse Multiplexing for ATM Trunk Module (IMATM) and ATM UNI service modules (AUSM) 8-port service modules (SMs) from version 4.0.x and 4.1.x to version 5.0.x.

The information presented in this document was created from devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If you are working in a live network, ensure that you understand the potential impact of any command before using it.

This document is intended to be used as an aid for conducting successful firmware upgrades and is not a substitute for proper planning with your Cisco Sales Engineer, Systems Engineer, or Account Manager.

Note: For MGX 8220 upgrades from firmware version 2.1.16 or 2.1.18 to 4.0.03, refer to Customer Upgrade Procedure: MGX 8220 2.1.18/16 to 4.0.03.
