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 PTX1000 chassis to connect to the earth ground (see
“Connecting the PTX1000 to Ground” on page 81).
•
Install the power supply in the chassis following the instructions in “Installing a Power Supply in a
PTX1000” on page 103.
•
Ensure that you have the following parts and tools available:
•
ESD grounding strap
•
Slotted (–) screwdriver, 1/4-in., with a torque range between 6 lb-in (0.68 Nm) and 7 lb-in (0.79 Nm)
CAUTION: You must use an appropriate torque-controlled tool to tighten the
screws on the DC power cable connector. Do not overtighten the screws. Applying
excessive torque damages the terminal block and the wiring tray. The absolute
maximum torque that may be applied to this screw is 10 lb-in (1.13 Nm).
•
Power cable or cables appropriate for your geographical location available to connect DC power to
the PTX1000. There are two types of DC power cables—a straight DC power cable
(CBL-JNP-PWR-DSUB) and a right-angle DC power cable (CBL-JNP-PWR-DSUB2 or
CBL-JNP-PWR-DSUB3). See “PTX1000 DC Power Cable Specifications” on page 47 for more
information.
CAUTION: Do not mix AC and DC power supplies in the same chassis.
NOTE: Each power supply must be connected to a dedicated power source outlet.
To connect DC power to a PTX1000:
1. To prevent damage to the equipment caused by static discharge, attach an ESD grounding strap to
your bare wrist, and connect the strap to an approved site ESD grounding point.
2. Ensure that the power supplies are fully inserted in the chassis and the latches are secure.
