X9716D-GX stuck on inserted state

[engtor113]

We've bought 9508 with X9716D-GX cards on it. The factory OS image was 15.3.2a 

We've upgrade it to the current fabric OS which is 6.3.0(e)

Later we've bought new X9716D-GX cards. But they stuck on inserted state. We've change the module slot, we've also change the working one's slot with non working one. Reload the switch, cut the electricity also didn't solve the problem. 

We've open a tac case. They've initiated RMA: but the new card is also  not working (in inserted  mode)

5 16 16p 400G Ethernet Module N9K-X9716D-GX ok
6 - - - inserted

I'm planning the downgrade the spine 15.3.2d( which has direct downgrade path from 16.0.3(e))  than re insert the non working cards then apply upgrade again?

Does it make sense?

Best wishes,

Hey @engtor113 

Yes, your plan to downgrade the spine to 15.3.2d and then reinsert the non-working cards before upgrading again does make sense as a troubleshooting step. Here's why and how it could help:

Why it makes sense:

1. Compatibility Issues: The new X9716D-GX cards might have a compatibility issue with the current fabric OS version (6.3.0(e)). Downgrading to the factory OS version (or a version closer to it, like 15.3.2d) could help confirm whether the issue is related to software compatibility.

2. Resetting the State: Downgrading and then reinserting the cards essentially resets the software environment to a known working state for the hardware. This can help rule out any issues introduced by the upgrade process.

3. Testing the Cards: If the cards work after the downgrade, it confirms that the issue is software-related and not hardware-related. If they still don't work, it points to a potential hardware issue or a deeper compatibility problem.

4. Direct Downgrade Path: Since 15.3.2d has a direct downgrade path from 16.0.3(e), this is a safe and supported operation.

Hope This Helps!!!

Have you tried another slot in the chassis or is this slot the only free one? If existing X9716D-GX cards are working and only new X9716D-GX cards are not working I would suspect the slot first then card firmware like EPLD/Bios.

Yes we’ve tried swapping slots. The problem is the OS size bigger than 2GByte. There is a bug related with it. It cannot copy the file for upgrade. We’ll try downgrade the chasis to 6.0.2(h) which is below 2Gbyte
