Voltage Check Procedure
Always check both AC and DC voltages during initial setup of the Model GS7000
Optical Hub.
Follow these steps to check AC and DC voltages.
1 Use a true-rms DVM to check for 45 to 90 VAC input voltage at the AC test point
on the power supply module.
2 Check for the various DC output voltages (+24.5, +8.5, -6.0, and +5.5) of the
power supply at the DC test points on the power supply module.
3 Verify that the Power ON LED on the receiver module is on.
4 Carefully close the housing lid. See Opening and Closing the Housing (on page
94).
