Applying Power to the Hub
OL-29936-01 41
Note: Shunts are available with both red and black tops. Use red to indicate
that power is applied to that port. Use black to indicate that input power is not
applied, but passed. Remove shunts to block AC power at the individual ports.
3 The next step depends on how many power supplies are installed and whether
or not you want power to pass through the hub. Use the following table to
determine the proper shunt installation.
