Proper way to link switches X440

[Peter_Donovan]

I am new to Extreme switches and I have a lab setup. I am using X440-24ps. How do I connect

Switch 1 SFP1 to Switch 2 SFP 1
Switch 1 SFP2 to Switch 3 SFP 1
Switch 1 SFP3 to Switch 4 SFP 1
Switch 1 SFP4 to Switch 4 SFP 1

Switch 1 SFP 1 thru 4 are ports 21-24 respectively
Switch 2 SFP 1 are port 24

Physically connecting seems to create issues of lost connectivity so I think I am missing something in the configuration portion.

No specific configuration required.

1. Could you please let me know what type of SFP's are used on all these switches?
2. What is the switch model and EXOS version running?
3. Collect the output for "debug hal show optic-info"?
4. What is the port and LED status on all switches?

For e.g: On Switch-1 use the command "show ports 21-24 no-refresh" and "show ports 21-24 configuration no-refresh" to check the status of port, etc..
