Cisco 12406 CSC revision A0 line cards may experience the following problems:
GSR6-CSC revision A0 cards generate invalid clock signal levels due to improperly placed termination resistors. This will affect both the operational and redundant CSC, resulting in CSC fail over not occuring or taking up to 13 seconds to complete.
GSR6-CSC cards fails to roll to the redundant CSC.
Cisco would like all customers with GSR6-CSC revision A cards to use the upgrade form below to request a CSC. "How to identify hardware revision" instructions are below.
Note: All 12406 CSC cards manufactured after April 2, 2002 do not have this problem.
This upgrade program will be available to customers through March 1, 2003.
