Chapter 5 Field Diagnostics for the Cisco 12000 Series Router

FPGA Overview

The following sample Cisco IOS boot text shows an FPGA upgrade message in bold text.

*Aug 19 14:51:06 UTC: %MBUS-6-FABCONFIG: Switch Cards 0x1F (bitmask) Primary Clock is CSC_1

Fabric Clock is Redundant Bandwidth Mode : Full Bandwidth

When this message is received, the Cisco 12000 Series Router field diagnostics are used to update the Flash memory with the new image. When using field diagnostics to update the FPGA, no actual test is initiated, only an update to the FPGA code. See the “Upgrade the FPGA Image on a Line Card” section on page 5-7.

When field diagnostics run, the target line card stops passing traffic, but the rest of the router continues passing traffic normally. The line card is loaded with the field diagnostics program, the Flash memory update is run, and, if successful, the card reboots to Cisco IOS. The entire process takes approximately 2 minutes per line card and must be done one line card at a time. It is a good practice to wait about 30 seconds after Cisco IOS reloads on the line card before updating the next line card. This gives the router a chance to synchronize all its internal functions. The following sample output shows the process involved in updating the FPGA code on a line card in slot 0.
