Verifying Power and Grounding Connections

To verify power and grounding connections:
1. Using a DVM, measure the voltage between pins 1 and 2 on the rear access
(NEBS) connector or between pins 2 and 3 of the front access (ETSI) connector.
2. Verify that voltage is –36 to –72 V DC. The inputs are protected against reverse
polarity.
