Cisco ONS 15500 Series

Field Notice: 15530-LCMB-0200 Requires Cisco Field-Programmable Gate Array (FPGA) Version 2.38 or Later

December 8, 2003

Products Affected

15530-LCMB-0200= If running Cisco field-programmable gate array (FPGA) version earlier than 2.38

Problem Description

When using the 15530-LCMB-0200= running FPGA 2.36 or earlier, ESCON clients may show link errors. These link errors are caused by cyclic redundancy check (CRC) errors originating from the ONS 15530 Chassis as it interfaces with the 15530-LCMB-0200=.


This issue was identified at a customer site and was corrected through an update to the FPGA image.

Problem Symptoms

When using the 15530-LCMB-0200= running FPGA version 2.36 or earlier, customers may see incrementing CRC errors and Code Violations. These incrementing CRC errors and Code Violations can be observed by using the CLI command show interface portgroup x/o/o (where x = slot number of ESCON card).


This issue has been resolved through an update to the Functional Image of the 15530-LCMB-0200=. Customers can download Functional Image Version 2.38, filename: fi-ons15530-escon.A.2-38.exo, from the Software Center.

To update a line card functional image from a flash memory device to a hardware controller, use the following command in privileged EXEC mode from a console session:

reprogram device:filename slot

The updated Functional Images can be downloaded from the Software Center on from the ONS 15530 FPGA Software.

The download process must be performed via local console access or local console access through a terminal server. The download process impacts traffic through the line card, so make certain to schedule a maintenance window to avoid unnecessary interruptions to customer traffic. Do not interrupt the download process. Wait for the process to complete before attempting any commands on the switch.
