Hi Marco,

Thanks for responding to this.

two different cases.

1. modules not came up on one of the s6100( LED's are blinking)

2. Modules came up on one of the s6100 (LED's not blinking)

Hi,

Was it working previously? What OS versions are they running? What errors are you getting? Did you try reloading again? Are they Dell optics?

Hi Mod,

Yes they were working before reboot.

They are running with 9.14.2.9

Tried the reboot couple of times but no luck, if we remove and install them back then they comes online.

Hi Chris,

I don't have extra modules to swap, and have already responded to john's queries.

Did any customer faced the similar issue?

Maybe some other customers can add their opinion but I wasn’t able to find anything that this is a known issue. When it is happening does show interfaces transceiver show stats for them? https://dell.to/3gTKbs3 Page 708

Hi John,

Switch modules are not coming up, so i am not able to see the interface stats.

What is the model number of the transceiver?

Hi John,

Following is the sfp module type.

QSFP type is 40GBASE-CR4

Actually the modules that are not coming up are 16 port switch modules which are installed in s6100.

S6100-MOD-16xETH40-F(Switch module)

Interesting they comes up, if we do hard reboot. but they are not coming up when we issue reload from switch.

is there anything to do with reload type?

Regards
