When I connect the 7937 to the data port on the floor, will not turn on at all.
If I connected to my 3750 port it comes on instantly.
What can it be wrong?
You would need this Part# only if you are using the Power Cube 3;
Optional Power Splitter for Cisco Unified IP Conference Station 7937G when using the Cisco Power Cube 3.
Hope this helps!
