CAT 6506 IOS 12.1(11b)E

Hi all,

the SYSTEM Led on the Supervisory Board lights yellow.

The sh env responses with

%C6KENV-SP-4-CLOCKFAILED: clock 2 failed

What does it mean and how can I fix this Problem?

The Error Message Interpreter does not have any response to that Error Message.

The cat 6500 has two system clocks on the backplane. These are necessary to time the forwarding of packets. You must have one working clock for packets to be forwarded. You can see which has failed by using the show test command, this will show which clock is being used and the result of any tests.

I suggest you speak to your hardware maintenance company regarding replacement.
