Cisco MGX 8200 Series Edge Concentrators

Incorrect AXIS 4.x Firmware Versions May Cause Service Modules to Appear to Have Failed


March 7, 1998



Products Affected

All AXIS parts supported in Release 2.1, 3.0 and 4.0.

Problem Description

When 4.0 firmware first became available to the field, a sudden rise occurred in instances of AXIS Shelf Controllers (ASCs) and Service Modules (SMs) being returned through the Cisco return materials authorization (RMA) policy due to wrong firmware. Investigation revealed that the RMAs were caused by the following:

  • Spare cards were delivered with incorrect firmware versions.

  • Download procedures were incorrect or confusing.

  • Service Modules with 4.X fiirmware may appear D.O.A. (Failed) when installed in an AXIS shelf equipped with an ASC running either 2.X or 3.X firmware.

Problem Symptoms

Service Modules may appear as "Failed" or in "Mismatch," or may not appear at all in the dspcds and dspcd display.

Workaround/Solution

Short-Term Solutions

Returned cards will now indicate the firmware version that is installed by changing the Product Number of the card.

Note:?See Table 1 at the end of this Field Notice for new part numbers. These part numbers are internal part numbers only, as of the date of this field notice. They do not currently appear on the web-based Configuration Agent or Pricing Agent found on Cisco Connection Online (CCO) nor do these part numbers appear in the Product Catalog. These part numbers are primarily for use by Cisco TAC and Cisco Service Logistics.

  • Cards will be marked with a pull off label that indicates the firmware Version, because once it is in the shelf the firmware can be changed.

  • The card will be labeled with a warning label about firmware Versions.

  • The shipping box will be labeled with the product number.

  • The shipping box will contain a "Read Me First" notice about firmware Versions.

  • The depots will be purged and restocked with parts that have these changes.

  • The default firmware level in order entry system will be removed.

  • Firmware download procedures will no longer be part of the Release notes, instead they will be placed on CCO. See the technical tip ASC and Service Module Firmware and Backup Boot Code Upgrade and Downgrade Techniques.

  • An Automated Script to perform the upgrade/downgrade has been developed for those users who have UNIX facilities.

  • Firmware revision 4.0.04 and later has some changes to improve the upgrade/downgrade process.

Long-Term Solutions

"Smart" boot that is common to all versions of firmware which will prevent cards from showing "Mismatch" or "Failed" or from not showing up at all, regardless of the SM firmware version or the ASC firmware version. The "smart" boot will need to be downloaded via TFTP to existing cards to take advantage of this feature. The TFTP procedure can be found in MGX 8220 Upgrade and Downgrade Techniques.

Note:?Beginning in May, 1998, the StrataCom AXIS concentrator will be renamed to the Cisco MGX 8220 edge concentrator. See Guide to New Names and Colors for WAN Switching Products for details about this and other changes to the WAN switching product line. The new part numbers listed in the table below will become effective in this time frame.
