I'm tring to stack 2 of these switches - both are H/W 1.0 and have F/W 1.0.2 Build 20160108 Release 59984(s)

 

I've powered up the units, hit reset on both and then powered them off connected them with a 0.5m passive SFP+ cable and powerd them back on.

 

Plugged a laptop into a 1GBe port, set it to 192.168.0.5/24, browsed to 192.168.0.1 

Enabled the two Stack Port Group 0 SFP+ ports

after a short wait, logged back in and verified that 1/0/25 and 1/0/16 say Status Down, Neighbor none

Saved the config

 

Plugged a laptop into the second switch's 1GBe port browsed to 192.168.0.1 

 

and connected them with an SFP+ 0.5m cable port 26 on one and 25 the other.

Enabled the two Stack Port Group 0 SFP+ ports

after a short wait, logged back in and verified that 1/0/25 and 1/0/16 say Status Down, Neighbor none

Saved the config

 

The powered them both off

unplugged the laptop from the switch

 

Power up one unit (with SFP+ in 1/0/25)

waited a minute until all the ports briedfly flash together

Power up the other unit (with SFP+ in 1/0/26)

 

The first one finishes booting with SYS flashing and the Master light on displaying "1" 

then the second switch finishes booting also with SYS flashing and the Master light on displaying "1" 

 

I can plug th elaptop into either switch, and browse around - the first switch reports AuthFail on 1/0/25, the other switch reports down for it's 1/0/26

 

I can configure either switch to work on our network, use NTP with a static link - just not get the stack working.

 

I tried anothe rsfp+ cable that I know works - same result.

I tried the other Port Group 1 .. same result

 

Is there a step missing ?

 

Thanks in advance

 

 

The system info shows the ports as green but Stack Info reports AuthFail
