Connecting The Ptx10003 To Ground - Juniper PTX10003-80C Hardware Manual

Connecting the PTX10003 to Ground

To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you
must connect the chassis to earth ground before you connect it to power. For installations that require a
separate grounding conductor to the chassis, use the protective earthing terminal on the PTX10003 chassis
to connect to the earth ground.
NOTE: An AC-powered PTX10003 gains additional grounding when you plug the power supply
into a grounded AC power outlet by using an AC power cord appropriate for your geographical
location. See "PTX10003 Power System" on page
CAUTION:
attach a cable lug to the grounding cables and power cables that you supply. A cable with
an incorrectly attached lug can damage the PTX10003 (for example, by causing a short
circuit).
NOTE: Mount the PTX10003 in the rack before attaching the grounding lug to the PTX10003.
