Connecting the PTX1000 to Power
Connecting the PTX1000 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 PTX1000 chassis to connect to the earth ground.
An AC-powered PTX1000 gains additional grounding when you plug the power supply in the device into a grounded AC power outlet by using an AC power cord appropriate for your geographical location. See PTX1000 AC Power Cord Specifications.
Before you connect power to the PTX1000, 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 PTX1000 (for example, by causing a short circuit).
Mount the PTX1000 in the rack before attaching the grounding lug to the PTX1000. See Mounting the PTX1000 in a Rack.
You must install the PTX1000 in a restricted-access location and ensure that the chassis is always properly grounded. The PTX1000 has a two-hole protective grounding terminal provided on the chassis. See Figure 1. We recommend that you use this protective grounding terminal as the preferred method for grounding the chassis regardless of the power supply configuration. However, if additional grounding methods are available, you can also use those methods. For example, you can use the grounding wire in the AC power cord or use the grounding terminal or lug on a DC power supply. This tested system meets or exceeds all applicable EMC regulatory requirements with the two-hole protective grounding terminal.
Ensure that you have the following parts and tools available:
-
Grounding cable—The grounding cable must be 8 AWG (8.4 mm²), minimum 90° C wire, or as permitted by the local code (not provided).
-
Grounding lug for your grounding cable—The grounding lug required is a Panduit LCC8-14A-L or equivalent (provided).
-
Two #10-32 UNF screws and washers (not provided).
-
Screwdriver appropriate for the #10-32 UNF screws (not provided).

Connecting AC Power to the PTX1000
Before you begin connecting AC power to the PTX1000:
Read AC Power Electrical Safety Guidelines and AC Power Disconnection Warning.
Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage (see Prevention of Electrostatic Discharge Damage).
Ensure that you have connected the PTX1000 chassis to earth ground.
CAUTION:Before you connect power to the PTX1000, 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 PTX1000 chassis to connect to the earth ground (see Connecting the PTX1000 to Ground).
Note:An AC-powered PTX1000 gains additional grounding when you plug the router’s power supply into a grounded AC power outlet by using an AC power cord appropriate for your geographical location. See PTX1000 AC Power Cord Specifications.
Install the power supply in the chassis following the instructions in Installing a Power Supply in a PTX1000.
Ensure that you have the following parts and tools available:
ESD grounding strap
Power cord or cords appropriate for your geographical location available to connect AC power to the PTX1000 (see PTX1000 AC Power Cord Specifications).
Do not mix AC and DC power supplies in the same chassis.
Each power supply must be connected to a dedicated power source outlet.

Connecting DC Power to the PTX1000
Before you begin connecting DC power to the PTX1000:
Read PTX1000 DC Power Electrical Safety Guidelines, and the following warnings:
Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage (see Prevention of Electrostatic Discharge Damage).
Ensure that you have connected the PTX1000 chassis to earth ground.
CAUTION:Before you connect power to the PTX1000, 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).

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).
Install the power supply in the chassis following the instructions in Installing a Power Supply in a PTX1000.
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 for more information.
DC-powered PTX1000 models are intended for installation only in a restricted-access location.
Do not mix AC and DC power supplies in the same chassis.
Each power supply must be connected to a dedicated power source outlet.
