Cisco CTS Boot-up Process/Check Marks

What codec does for each check:

0. = UBoot init completed (Cisco logo lid)

1. = CTS image header verified.

2. = Loading CTS image from CF to RAM

3. = Image loading from CF continued..

4. = Image loading from CF continued..

5. = CTS image checksum verified. Load Ramdisk & Pass control to


6. = To Linux, establish network, Kernel in control (nv mounted)

When CTS boots up and doesn't pass all 6 green check, or stuck in one of them, it normally suggests HW failure or NV corruption.


In most of the cases, RMA of the codec is suggested as No further Trouleshooting is possible.
