I stacked two 3750G Cisco switches a few weeks ago, all go. But, yesterday I installed a 2nd stacking cable as well for full optimization. However, it is not registering it seems.
Cisco3750#sh switch stack-ports
Switch # Port 1 Port 2
-------- ------ ------
1 Ok Down
2 Ok Down
I did a little Googling, found these two. Is this the correct way to enable the 2nd stacking cable?
switch 1 stack port 2 enable
switch 2 stack port 2 enable
EDIT 4PM: Another search says to cross the cables (crisscross). Not sure what's up here, but the above commands to enable did not cut it.
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.
UPDATE #2 10:30PM
Powered off, looped stacking cables as suggested, powered on. Shows the loop (port 1 to port 2, vice versa) but 2nd cable still not registering.

Enabling/disabling a stack port may cause undesired stack changes. Continue?[confirm]
Cisco3750#switch 2 stack port 2 enable
