Thanks for helping

Do you use a DAC (direct attached copper cable) for it? Because for this 10port-models the stacking speed is 5G only this direct cable are working.

[tchup]

no just connectors + RJ45 !
there is no specific cable on the datasheet

[tchup]

I found this :
https://www.al-enterprise.com/-/media/a ... eet-en.pdf

OS6450S-CBL-60 = 60 cm long SFP+ direct stacking cable for OS6450 24- and 48-port models
but not for 10 ports models...

I will test

[silvio]

this cable works too for 10port-models. You have to use the stacking ports 11 and 12 (SFP).

Hi,

i don't understand

You have to use the stacking ports 11 and 12 (SFP).

the stack now works with OS6450S-CBL-60 and command line "stack set slot 1 mode stackable"

thanks

[silvio]

with the command "stack set slot 1 mode stackable" you change the function of the ports 11 and 12 from normal uplink to stack (stk A and stk B). Only this ports are possible for stacking. Because it works now you have done this correctly.
