Connecting Ac Power To The Ptx10003 - Juniper PTX10003-80C Hardware Manual

Connecting AC Power to the PTX10003

The power supplies automatically detect whether there is AC or HVDC input voltage and manage the
power accordingly. Each 3000 W AC/HVDC power supply module has a single AC or HVDC input and
provides 12 V power to the system. The power supply in a PTX10003 is a hot-removable and hot-insertable
field-replaceable unit (FRU). After removing the power cord from an individual power supply, you can
remove and replace it without powering off the router or disrupting router functions.
Ensure that you have a power cord appropriate for your geographical location available to connect AC
power to the router.
