Hi I am unboxing 2x cartons of C4510RE chassis and find this booting up fault consistently appearing in both chassis.

Has anyone encountered this before?

    Which chassis specifically? I know of a WS-C4510R-E and a WS-C4510R+E, but not a WS-C4510RE. Also, which supervisor(s) and in which slots are the supervisors installed? Are you trying to boot the image that came on the supervisors, or have you replaced it?

Looks like a bug. Get tech support.

In the meantime you can try and narrow down the problem by restarting your switches with the smallest possible hardware and software configuration and see what triggers the problem.

(1) Hardware: 4510RE is a dual-supervisor chassis with line cards. So, pull out all the line cards, pull out the redundant power supply, pull out the redundant supervisor, and start with just the one supervisor and see if the abnormal termination still happens. If it does, you really have no option other than to wait for support. If it boots fine, then you can try inserting all the removed components one-by-one.

(2) Software: Sometimes abnormal terminations can happen when there is something in the startup-configuration that the software does not "digest" properly. Cisco provides a way to boot the device by not reading the startup-configuration (this is actually a part of the password recovery process) - you can try this process and see if there is something in the startup-configuration that is causing the problem.

To reiterate: the above is just a stopgap arrangement until your tech support finds the problem. My personal opinion is that is is better to just wait for support.

  • Thank you @mere3ortal , i will try your recommended steps and update you on my findings

  • OK, but you've just worked around the problem. Once you configure your switch to do something useful (like, you know, switch packets :-)), it's possible the problem may come back - but at least now you'll know what line of configuration is causing the problem.

  • The issue reappear after I insert 6 line cards , I further isolate the issue by inserting the line cards 1 by 1 and booting up 1 increment at a time and discover faulty line card at slot 7 and replaced it with working 1. Now it’s fine.
