How to Install a JNP10K-PWR-DC Power Supply

Before you install a JNP10K-PWR-DC 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 secure the handle of the circuit breaker in the OFF position using tape.

CAUTION:

Before you connect power to the router, a licensed electrician must attach a cable lug to the grounding cable 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 and DC power supplies in the same chassis.

CAUTION:

To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must connect MX10016 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 an MX10016 router to ground using a separate grounding conductor, see Connect an MX10016 to Earth Ground.

Note:

Each battery return of the JNP10K-PWR-DC 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 JNP10K-PWR-DC power supply:

    • Electrostatic discharge (ESD) grounding strap

    • DC power source cables (not provided) with the cable lugs (provided) attached

      The provided terminal lugs in an MX10016 are sized for 4 AWG (21.1 mm2) power source cables. The DC power source cables that you provide must be 4 AWG (21.1 mm2), minimum 70° C wire. We recommend that you install heat-shrink tubing insulation around the crimped section of the power cables and lugs.

      Note:

      See the heat symbol . Wear heat-resistant gloves while accessing the fan tray and power supply.

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

    • Phillips (+) screwdrivers, numbers 1 and 2

    • Multimeter

You can install a power supply in any slot labeled PSU 0 through PSU 9 on an MX10016.

The JNP10K-PWR-DC power supply in an MX10016 chassis is a hot-removable and hot-insertable field-replaceable unit (FRU). You can install up to 10 JNP10K-PWR-DC power supplies in an MX10016 router chassis. All DC power supplies install in the rear of the chassis in the slots along the left side of the chassis.

To install a JNP10K-PWR-DC power supply in an MX10016 (see Figure 19):

  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 9 on the MX10016 rear panel (see Figure 15).

  2. Taking care not to touch the power supply components, pins, leads, or solder connections, remove the power supply from its bag.
    CAUTION:

    See the heat symbol . The power supply surfaces are hot. Allow a few minutes for the power supply to cool by pulling the power supply halfway out of the chassis, or wear heat-resistant gloves while removing the power supply.

  3. Peel back and remove the protective plastic wrap that covers all four sides of the power supply.
  4. Ensure the power switch of the power supply is set to the standby (O) position. This switch turns off the output voltage; it does not interrupt DC power supply.
  5. Remove the plastic cable cover from the DC power input terminals by using the number 2 Phillips (+) screwdriver, to loosen the screws (see Figure 16).
    Figure 16: Removing the Plastic Cable CoverRemoving the Plastic Cable Cover
  6. Remove the nuts from each DC power supply 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 supply.
  8. Verify that the DC power cables are correctly labeled before connecting them 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 must be connected to the –48V (input) DC power input terminal.

    • The cable with very low resistance (indicating a closed circuit) to chassis ground is positive (+) and must be connected to 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 the lug with a nut (see Figure 17). 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.

    Figure 17: Connecting DC Power Supply Cables to an MX10016Connecting DC Power Supply Cables to an MX10016

    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, and also, there is basic insulation between the RTN input feeds.

  10. Install the plastic cable cover over each set of power cables by using the number 2 Phillips (+) screwdriver, 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 then pull the cover panel out of the slot. Save the cover panel for later use (see Figure 18).
    Figure 18: Removing the Cover Panel of a Power Supply on an MX10016Removing the Cover Panel of a Power Supply on an MX10016
  12. Unscrew the captive screw by turning it counterclockwise by using the number 1 Phillips (+) screwdriver.

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. SeeMX10016 Power Planning and Power Requirements for MX10016 Components.

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 an MX10016 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_9 on the MX10016 (see Figure 21).

  6. Put on the heat resistant gloves to protect your hands from the hot power supply.
  7. Taking care not to touch power supply components, pins, leads, or solder connections, place one gloved hand under the power supply to support it. Grasp the power supply handle with your other hand and pull the power supply completely out of the chassis.
  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

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, router the circuit breaker to the OFF position, and tape the router 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 MX10016 router 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 an MX10016 router to ground using a separate grounding conductor, see Connect an MX10016 to Earth Ground.

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

The JNP10K-PWR-DC2 power supply in an MX10016 chassis is a hot-removable and hot-insertable field-replaceable unit (FRU). You can install up to 10 power supplies in an MX10016 router chassis. All HVDC power supplies install in the rear of the chassis in the slots along the left side of the chassis.

To install a JNP10K-PWR-DC2 power supply in an MX10016 :

  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_9 on the MX10016 (see Figure 23).

  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 24).
    Figure 24: Removing the Plastic Cable Cover on a JNP10K-PWR-DC2 Power SupplyRemoving 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 25). 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. 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 26).

  12. Unscrew the captive screw in the counterclockwise direction by using the Phillips (+) screwdriver, number 1.
  13. Rotate the captive screw away from the faceplate of the power supply to release the latch.
  14. Using both hands, place the power supply in the power supply slot on the rear of the router. Slide the power supply straight into the chassis until the power supply is fully seated in the slot. The power supply will protrude from the chassis about 2 in. (5 cm) (see Figure 27).
  15. Push the captive screw into the power supply faceplate. Ensure that the screw is seated inside the corresponding hole on the faceplate.
  16. Tighten the captive screw by turning it clockwise by using the Phillips (+) screwdriver, number 1. When the screw is completely tight, the latch locks into the router chassis.

    Warning:

    Ensure that the power cords do not block access to router components or drape where people can trip on them.

  17. Route INP1 cables to a power source and INP2 to another power source. The JNP10K-PWR-DC shares power, so if power dips on one input, the power supply is able to load balance internally. See Figure 28.

    Warning:

    Ensure that the power cords do not block access to router components or drape where people can trip on them.

  18. Set the three dip switches to select the inputs and confirm whether the power supply is running with 60 A or 80 A input feeds. Set switch 1 (IP0) to the on position to enable A0 and B0 inputs. Set switch 2 (IP1) to the on position to enable A1 and B1 inputs. The A and B inputs are redundant feeds to each input (0 and 1). Set switch 3 (H/L) to the on position for 80 A input feed (2750 W in single input mode and 5500 W in dual input mode) and set it to the off position for 60 A feed (2200 W in single input mode and 4400 W in dual input mode). See Figure 29.

    Set both enable switches (switch 1 and 2) to the on position when using both source inputs (0 and 1). When using single DC input feed, set the unused source switch to the off position. The Fault LED turns red and indicates an error if a source input is not in use and the enable switch is turned on.
