A9K-8HG-FLEX-TR not booting with A9K-RSP880-LT-TR running IOS XR 7.9.3

[nesttech1]

We are trying to set-up A9K-8HG-FLEX-TR in the ASR-9906 chassis with redundant A9K-RSP880-LT-TR and running IOS XR 7.9.3, but after about 2 hours the module is still in the SW_INACTIVE state.  All the lights on the module are amber color, but it does not come up.  Does not show any error messages at all.

We have tried another A9K-8HG-FLEX-SE in the same chassis and with the same RSPs and it comes up OK.

Let me know if you have any recommendations.

i do not see any reason since you have enough power on the chasis to supply enough power to card to boot.

as you mentioned other card working fine., i suspect some hardware fault, what logs you see on the console other than SW_INACTIVE

also worth open a TAC case.

There are absolutely no error logs on the console.

Typically, the first time the module is booted it can take 20-40 minutes for it to become active, but we have waited over 2 hours and nothing happens at all.
