Do i need to order network module (C3KX-NM-1G) to stack two 3750X Switch other than stacking cable?
No. The network module, in the -X series, it to allow differ uplink ports.
What you might need to order it a stacking cable of a longer length. From Cisco, stacking cables come in three lengths. Don't know if still true, but it used to be, I believe, that a 3750 would come standard with the shortest stacking cable which is long enough to go between nearby units when physically stacked vertically together. In larger physically stacks, you would often need to order the longer cable to go between top and bottom stack units.
A bit off topic, but is anyone aware of issues running IOS 15 with the 3 meter cables?
I upgraded several 3750X stacks from 12.2(55)SE8 to 15.0(2)SE5, and one of the stacks failed to talk to each other following the upgrade. It detected cables, but could not detect the other member. Downgraded IOS and everything worked fine again. The only difference between that stack and the others was 3M cables rather than the standard 50cm ones.
