I set up stacking between two 3750G switches and yesterday, installed a 2nd stack cable among them. I noticed the "stack" light is not on either one. Is this normal? Shouldn't it be on? How can I absolutely confirm via CLI that the stacking cables are indeed in effect? I'm 99% the 1st is. It was installed 2 weeks ago and via CLI, show run shows 48 ports (24 per switch) so that's all go but I also want to confirm the 2nd as well.

Google search, found a link that explained looping
Original output
Code:
Cisco3750#sh switch stack-ports
Switch # Port 1 Port 2
-------- ------ ------
1 Ok Down
2 Ok Down
So I tried this. Powered off, looped stacking cables as suggested by others, powered on. Shows the loop (port 1 to port 2, vice versa) but 2nd cable still not registering. That's my issue here. I'm trying to get the full ring config and 32GB ring speed (full capacity).Each 3750 switch’s back has two stack ports 1 and 2.
Suppose you want to connect two switches with two stack cables:
1st switch port 1 connects to 2nd switch port 2.
1st switch port 2 connects to 1st switch port 1.
The stack cables will be crossed.
Code:
Cisco3750#sh switch stack-ports
Switch # Port 1 Port 2
-------- ------ ------
1 Ok Down
2 Down Ok
Cisco3750#show switch stack-ring speed
Stack Ring Speed : 16G
Stack Ring Configuration: Half
Stack Ring Protocol : StackWise
