Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage
(see “Prevention of Electrostatic Discharge Damage” on page 205 ).
CAUTION: Before you connect DC power to the PTX10003, a licensed electrician
must attach a cable lug to the grounding and power cables that you supply. A cable
with an incorrectly attached lug can damage the router (for example, by causing a short
circuit).
NOTE: 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 (see “Connecting the PTX10003
to Ground” on page 110 ).
NOTE: For Junos OS Evolved software release 19.1, the PTX10003 does not support a 60 A
power source.
•
Install the DC power supply in the chassis. See “Maintaining the PTX10003 Power Supplies” on page 134 .
The battery returns of the DC power supply must be connected as an isolated DC return (DC-I).
•
Ensure that you have the following parts and tools available:
•
ESD grounding strap (provided)
•
Phillips (+) screwdriver, 1/4-in., with a torque range between 6 lb-in. (0.68 Nm) and 7 lb-in. (0.79 Nm)
(not provided)
CAUTION: You must use an appropriate torque-controlled tool to tighten the
hex-nuts on the DC power cable connector. Do not overtighten the hex-nuts. Applying
excessive torque damages the terminal block and the wiring tray.
