Flexstack catalyst cisco 2960XR problem

[max15]

Good afternoon, colleagues!
I have a problem with association of a stack cisco WS-C2960RX-48FPS-L . 6 switches integrated, 2 more did not integrate.
I changed stack module, cable stack, priority, provision, renumber, fully cleared all configs to make switches as from factory, changed firmware. However the problem did not disappear.

Tried on ios 15.2.4.e3, 15.2.4.e7, 15.2.6.e2.
If it's necessary I will send a config. Help me!!!  Thank you!

Hi,
All firmwares of one version, wire all are connected correctly, a photo in attachment.

Hello

Seams to suggest you have problem either with one of the flex modules  in sw1 or 6 or a flex cable.
sh switch stack-ports summary

it does not work, and everything works with these wires and modules. I tried to interchange the position of them.

Switch#show switch stack-ports ?

Switch#show switch stack-ports
  Switch #    Port 1       Port 2
  --------    ------       ------
    1          Down          Ok
    2           Ok           Ok
    3           Ok           Ok
    4           Ok           Ok
    5           Ok           Ok
    6           Ok          Down

Not so sure i understand -  you say if you change the modules around into the other switches then those same modules work but just not in switch 1 and 6?

all modules work in switches and in the first stack and in the second if you change them, for some reason they are not friends with each other ,both stacks are not connected to one. But the modules and the wire stack work properly.

When you say stacks you mean switches not stacks correct - you are not trying to connect two separate stacks together are you?

Good afternoon everyone, help, I really need a solution to the problems. Maybe there are more examples in the solution?

We have suggested this option may be you have not tried in the post i have not seen it that tried.

Remove all the config of all switches, make it factory default.

1. Power them off all the switches. ( we expect no config on the switches here)

2. start master switch first let boot all the way until command promopt, connect the console cable to master switch. - keep capture all the logs, this is very important to understand the issue.

3.  Power ON Switch2 - once it booted

4.  Power ON Switch3 - once it booted

5.  Power ON Switch4 - once it booted

6.  Power ON Switch5 - once it booted

7.  Power ON Switch6 - once it booted

8.  Power ON Switch7 - once it booted

9.  Power ON Switch8 - once it booted

By now all the switches booted, check all part of stack now ? and post the complete logs you capture before

along with show switch, show stack information.
