It is possible for the value of an alphanumeric LED to be reversed. For example, IOS RUN may be
displayed as RUN IOS.
If the alphanumeric LEDs on the line card display anything other than IOS RUN, or the RP is neither the
active Master/Primary nor the Slave/Secondary, there is a problem and the line card has not fully loaded
correctly. Before replacing the line card, try fixing the problem by following these steps:
Reload the microcode using the global configuration microcode reload slot command.
Reload the line card using the hw-module slot reload command. This causes the line card to reset and
download the MBus and fabric downloader software modules before attempting to download the Cisco
Reset the line card manually. This may rule out any problems that are caused by a bad connection to the
MBus or switching fabric.
Fabric Ping Failure
Fabric ping failures occur when either a line card or the secondary RP fails to respond to a fabric ping
request from the primary RP over the switch fabric. Such failures are a problem symptom that should be
investigated. They are indicated by the following error messages:
%GRP-3-FABRIC_UNI: Unicast send timed out (1)
%GRP-3-COREDUMP: Core dump incident on slot 1, error: Fabric ping failure
%LCINFO-3-CRASH: Line card in slot 1 crashed

Timeouts and Failures on the Cisco 12000 Series Internet Router publication.
If you receive any error message related to a line card, you can use the Error Message Decoder Tool (on
Cisco.com) to find the meaning of this error message. Some errors point to a hardware issue, while others
indicate a Cisco IOS software caveat or a hardware issue on another part of the router. This publication
does not cover all these messages.
Some messages related to Cisco Express Forwarding (CEF) and Inter Process-Communication (IPC) are
