  6. Remove the nuts from each DC power input terminal, using the 13/32 in. (10 mm) nut driver or socket wrench to loosen the nuts.
  7. Ensure that the power source circuit breaker is open so that the voltage across the DC power source cable leads is 0 V and that the cable leads do not become active while you are connecting DC power.
  8. Verify that the DC power cables are correctly labeled before making connections to the power supply. In a typical power distribution scheme where the return is connected to chassis ground at the battery plant, you can use a multimeter to verify the resistance of the –48V and RTN DC cables to chassis ground:
    • The cable with very high resistance (indicating an open circuit) to chassis ground is negative (–) and will be installed on the –48V (input) DC power input terminal.

    • The cable with very low resistance (indicating a closed circuit) to chassis ground is positive (+) and will be installed on the RTN (return) DC power input terminal.

    Caution

    You must ensure that power connections maintain the proper polarity. The power source cables might be labeled (+) and (–) to indicate their polarity. There is no standard color coding for DC power cables.

  9. Install each power cable lug on the DC power input terminal, securing it with the nut (see Figure 29). Apply between 24 in.-lb (2.7 Nm) and 25 in.-lb (2.8 Nm) of torque to each nut. (Use the 13/32 in. [10 mm] nut driver or socket wrench.)
    1. Secure each positive (+) DC source power cable lug to the RTN (return) DC power input terminal.

    2. Secure each negative (–) DC source power cable lug to the –48V (input) DC power input terminal.

    Each power supply has two independent sets of DC power input terminals (INPUT 1: RTN –48V/–60V: and INPUT 2: : RTN –48V/–60V). For feed redundancy, each power supply must be powered by dedicated power feeds derived from feed INPUT 1 and feed INPUT 2. This configuration provides the commonly deployed INPUT 1 / INPUT 2 feed redundancy for the router. There is basic insulation between the inputs and the chassis ground. Also, there is basic insulation between RTN input feeds.

  10. Install the plastic cable cover over each set of power cables by using the Phillips (+) screwdriver, number 2, to tighten the screw.
  11. If the power supply slot on the chassis has a cover panel on it, insert your thumb and forefinger into the finger holes, squeeze, and pull the cover out of the slot. Save the cover panel for later use (see Figure 30 for PTX10008 installations and Figure 31 for PTX10016 installations).

How to Remove a JNP10K-PWR-DC2 Power Supply

The JNP10K-PWR-DC2 power supply in a PTX10000 chassis is a hot-removable and hot-insertable field-replaceable unit (FRU). You remove power supplies from the rear of the chassis.

Caution

A working JNP10K-PWR-DC2 power supply can reach temperatures of 158°F (70°C); In order to avoid injury, do not touch a running power supply with your bare hands.

Caution

Before you remove a power supply, ensure that you have power supplies sufficient to power the router left in the chassis. See PTX10008 Power Planning and Power Requirements for PTX10000 Components.

Before you remove a DC power supply from the router:

Ensure that you have the following parts and tools available to remove a DC power supply:

  • Heat protective gloves able to withstand temperatures of 158°F (70°C)

  • Electrostatic discharge (ESD) grounding strap

  • Phillips (+) screwdriver, numbers 1 and 2

  • 13/32 in. (10 mm) nut driver or socket wrench

  • Replacement power supply or a cover panel for the power supply slot

Caution

Do not leave the power supply slot empty for a long time while the router is operational. Either replace the power supply promptly or install a cover panel over the empty slot.

To remove a JNP10K-PWR-DC2 power supply from a PTX10000 router:

  1. Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis. There is an ESD point located next to the protective earthing terminal and below PSU 5 on the PTX10008 rear panel (see Figure 35 and below PSU_9 on the PTX10016 (see Figure 36).

  8. If you are not replacing the power supply, install the cover panel over the slot.
    1. Insert your thumb and forefinger into the finger holes of the cover panel.
    2. Squeeze and place the cover in the slot.
    3. Release your fingers and the cover remains in the slot.
  9. Unscrew the screw on the plastic cable cover that shield the input terminal studs counterclockwise by using the Phillips (+) screwdriver, number 2.
  10. Unscrew the nuts counterclockwise using the 13/32 in. (10 mm) nut driver or socket wrench from the input terminal studs.
  11. Remove the cable lugs from the input terminal studs.

How to Install a JNP10K-PWR-DC2 Power Supply

The JNP10K-PWR-DC2 power supply in a PTX10000 chassis is a hot-removable and hot-insertable field-replaceable unit (FRU). You can install up to 6 power supplies in a PTX10008 router chassis. All HVDC power supplies install in the rear of the chassis in the slots along the left side of the chassis.

Before you install an HVDC power supply in the chassis, ensure that you have followed all safety warnings and cautions:

Warning

Before performing DC power procedures, ensure that power is removed from the DC circuit. To ensure that all power is off, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.

Warning

Protect yourself from severe burns by wearing heat-protective gloves when removing a working HVDC power supply from the chassis. HVDC power supplies can reach 158°F(70°C).

Caution

Before you connect power to the router, 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).

Caution

Do not mix AC, DC, or HVDC power supplies in the same running chassis. You can mix DC and HVDC power supplies while swapping out one type for another during installation.

Caution

To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must connect PTX10008 routers to earth ground before you connect them to power. For installations that require a separate grounding conductor to the chassis, use the protective earthing terminal on the router chassis to connect to earth ground. For instructions on connecting a PTX10000 router to ground using a separate grounding conductor, see Connecting Earth Ground to a PTX10000.

Note

The battery returns of the JNP10K-PWR-DC2 power supply must be connected as an isolated DC return (DC-I).

  • Ensure you understand how to prevent ESD damage. See Prevention of Electrostatic Discharge Damage.

  • Ensure that you have the following parts and tools available to install a DC power supply:

    • Electrostatic discharge (ESD) grounding strap

    • Use high current cable assembly, CBL-PWR2-BARE (not provided) with the cable lugs (provided) attached

      The provided terminal lugs for the JNP10K-PWR-DC2 are Panduit LCD4-14A-L, or equivalent, and sized for 4 AWG (21.1 mm2) power source cables. We recommend that you install heat-shrink tubing insulation around the crimped section of the power cables and lugs.

    • 13/32 in. (10 mm) nut driver or socket wrench

    • Phillips (+) screwdrivers, numbers 1 and 2

    • Multimeter

To install a JNP10K-PWR-DC2 power supply in a PTX10008 or PTX10016 :

  1. Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis. There is an ESD point located next to the protective earthing terminal and below PSU 5 on the PTX10008 rear panel (see Figure 39) and below PSU_9 on the PTX10016 (see Figure 40).

  2. Taking care not to touch power supply components, pins, leads, or solder connections, remove the power supply from its bag.
  3. Peel back and remove the protective plastic wrap that covers all four sides of the power supply.
  4. Ensure the power switch is set to the standby (O) position. This switch turns off the output voltage; it does not interrupt DC.
  5. Remove the plastic cable cover from the power input terminals by using the Phillips (+) screwdriver, number 2, to loosen the screws (see Figure 41).
    Figure 41: Removing the Plastic Cable Cover on a JNP10K-PWR-DC2 Power Supply
    Removing the Plastic Cable Cover on a JNP10K-PWR-DC2 Power Supply
  6. Remove the nuts from each DC power input terminal, using the 13/32 in. (10 mm) nut driver or socket wrench to loosen the nuts.
  7. Ensure that the power source circuit breaker is open so that the voltage across the DC power source cable leads is 0 V and that the cable leads do not become active while you are connecting DC power.
  8. Verify that the DC power cables are correctly labeled before making connections to the power supply. In a typical power distribution scheme where the return is connected to chassis ground at the battery plant, you can use a multimeter to verify the resistance of the –48V and RTN DC cables to chassis ground:
    • The cable with very high resistance (indicating an open circuit) to chassis ground is negative (–) and will be installed on the –48V (input) DC power input terminal.

    • The cable with very low resistance (indicating a closed circuit) to chassis ground is positive (+) and will be installed on the RTN (return) DC power input terminal.

    Caution

    You must ensure that power connections maintain the proper polarity. The power source cables might be labeled (+) and (–) to indicate their polarity. There is no standard color coding for DC power cables.

  9. Install each power cable lug on the DC power input terminal, securing it with the nut (see Figure 42). Apply between 24 in.-lb (2.7 N-m) and 25 in.-lb (2.8 N-m) of torque to each nut. (Use the 13/32 in. [10 mm] nut driver or socket wrench.)
    1. Secure each positive (+) DC source power cable lug to the RTN (return) DC power input terminal.

    2. Secure each negative (–) DC source power cable lug to the –48V (input) DC power input terminal.

    Each power supply has two independent sets of DC power input terminals (INPUT 1: RTN –48V/–60V: and INPUT 2: : RTN –48V/–60V). For feed redundancy, each power supply must be powered by dedicated power feeds derived from feed INPUT 1 and feed INPUT 2. This configuration provides the commonly deployed INPUT 1 / INPUT 2 feed redundancy for the router. There is basic insulation between the inputs and the chassis ground.
