Field Notice: Wrong Version of Cisco IOS Software Bundled into MGX8250 1.1.24 Release

September 5, 2000

Products Affected

MGX Release 1.1.24

Problem Description

Through an error, Cisco IOS Software Release 12.1(1)T was incorrectly bundled with MGX 1.1.24. The MGX 1.1.24 release supports the MGX 8230, MGX 8250, and MGX 8850 products. The correct version to use with MGX 1.1.24 is Cisco IOS Software Release 12.1(3)T or later.


Since the introduction of the RPM series of modules into the MGX8850 and MGX8250 series, a compatible Cisco IOS Software Release has been bundled into the MGX release. Through an error, a version of Cisco IOS Software that is not compatible with the RPM in certain applications was bundled into MGX software release 1.1.24.

Problem Symptoms

The RPM will behave unpredictably if it is loaded with Cisco IOS Software Release 12.1.(1)T.


If you are a registered CCO user and you have logged in, download Cisco IOS Software Release 12.1.(3)T from the CCO Software Center. Make sure you download Cisco IOS Software Release 12.1.3T for the RPM. Load this version onto the MGX8250 or MGX8850. Download the boot image and the Cisco IOS image and follow the upgrade procedures described in the MGX8800 User Guide. Cisco IOS Software Release 12.1(3)T or later is the recommended release to use with 1.1.24 MGX software.
