Powering Up The Dsu; Power-Up Routine - Paradyne COMSPHERE 3610 Quick Reference Manual

Powering Up the DSU

CAUTION:
The power cord contains a 3-wire grounding-type plug which has a
grounding pin. This is a safety feature. Grounding of the unit is vital to ensure
safe operation. Do not defeat the purpose of the grounding plug by modifying
it or by using an adapter. Prior to installation, use an outlet tester or voltmeter
to check the ac receptacle for earth ground. If the power source does not
provide a ground connection, consult an electrician to determine another
method of grounding the unit before proceeding with the installation.
