Connecting Power

Step 7 Tighten the receptacle screws and nuts for the +48V and –48 VDC input leads.

Step 8 Run the +48V and –48V leads through the strain-relief on the top of the power supply faceplate and connect the leads to the DC power supply (+48V and –48V).

Step 9 Adjust the voltage on the DC power supply to approximately –48 VDC.

Note Wait until the system has been cabled before turning on the power supply. See the “Powering On the RF Switch” section on page 5-26.
