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 MX10000 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 MX10000 router to ground using a separate grounding conductor, see Connect the MX10008 to Earth Ground.

Note:

Each battery return of the 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 MX10000 are sized for either4 AWG (21.1 mm2) or 6 AWG (13.3 mm2) power source cables. When running all JNP10K-PWR-DC power supply modules in the chassis, the DC power source cables that you provide must be 6 AWG (13.3 2) mm²) stranded wire We recommend that you install heat-shrink tubing insulation around the crimped section of the power cables and lugs.

      Note:

      If you upgrade the JNP10K-PWR-DC to a JNP10K-PWR-DC2 and set the input mode to high (80-A), you must use 4 AWG (21.1 mm²) stranded wire.

      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

The JNP10K-PWR-DC power supply in an MX10008 and MX10016 chassis is a hot-removable and hot-insertable field-replaceable unit (FRU). You can install up to 6 JNP10K-PWR-DC power supplies in an MX10008 router chassis and 10 in an MX10016 router chassis. All 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 MX10000:

  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 MX10008 rear panel (see Figure 40) and below PSU_9 on the MX10016 rear panel (see Figure 41).

  2. Taking care not to touch 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 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 DC power input terminals by using the Phillips (+) screwdriver, number 2, to loosen the screws (see Figure 42).
    Figure 42: Removing the Plastic Cable Cover on an MX10008 DC Power SupplyRemoving the Plastic Cable Cover on an MX10008 DC 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. Install a power lug on each DC power cable. Ensure the lug meets the double hole standard lug terminal for 4 AWG wire. The lugs should be dual, 1/4 in. spaced 5/8 in. apart. The terminal must accommodate double hole standard lug terminal for 4 AWG or larger wire.
  9. 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.

  10. Install heat-shrink tubing insulation around the power cables.

    To install heat-shrink tubing:

    1. Slide the tubing over the portion of the cable where it is attached to the lug barrel. Ensure that tubing covers the end of the wire and the barrel of the lug attached to it.

    2. Shrink the tubing with a heat gun. Ensure that you heat all sides of the tubing evenly so that it shrinks around the cable tightly.

    Figure 43 shows the steps to install heat-shrink tubing.

    Note:

    Do not overheat the tubing.
    Figure 43: How to Install Heat-Shrink Tubing How to Install Heat-Shrink Tubing
  11. Install each power cable lug on the DC power input terminal, securing it with the nut (see Figure 44). 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 44: Connecting the DC Power Supply Cables to an JNP10K-PWR-DC Connecting the DC Power Supply Cables to an JNP10K-PWR-DC

    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.

  12. Install the plastic cable cover over each set of power cables by using the Phillips (+) screwdriver, number 2, to tighten the screw.
  13. 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 45 for MX10008 installations and Figure 46 for MX10016 installations).
    Figure 45: Removing the PSU Cover Panel on an MX10008Removing the PSU Cover Panel on an MX10008
    Figure 46: Removing the Power Supply Cover Panel on an MX10016Removing the Power Supply Cover Panel on an MX10016
  14. Unscrew the captive screw in the counterclockwise direction by using the Phillips (+) screwdriver, number 1.
  15. Pull the captive screw away from the faceplate of the power supply to release the latch. You can install the power supplies in any slot labeled PSU 0 through PSU 5 (top to bottom) on an MX10008 and PSU 0 through PSU 9 on an MX10016.
  16. Using both hands, place the power supply in the power supply slot on the rear of the router.
  17. Slide the power supply straight into the chassis until the power supply is fully seated in the slot. Ensure the power supply faceplate is flush with any adjacent power supply faceplates or power supply cover panels (see Figure 47 and Figure 48).
  18. Push the captive screw into the power supply faceplate. Ensure that the screw is seated inside the corresponding hole on the faceplate.
  19. 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.

The JNP10K-PWR-DC2 power supply in an MX10000 chassis is a hot-removable and hot-insertable field-replaceable unit (FRU). You can install up to 6 power supplies in an MX10008 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 MX10008 or PMTX10016 :

  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 MX10008 rear panel (see Figure 56) and below PSU_9 on the MX10016 (see Figure 57).

  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 58).
    Figure 58: 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 heat-shrink tubing insulation around the power cables.

    To install heat-shrink tubing:

    1. Slide the tubing over the portion of the cable where it is attached to the lug barrel. Ensure that tubing covers the end of the wire and the barrel of the lug attached to it.

    2. Shrink the tubing with a heat gun. Ensure that you heat all sides of the tubing evenly so that it shrinks around the cable tightly.

    Figure 59 shows the steps to install heat-shrink tubing.

    Note:

    Do not overheat the tubing.
    Figure 59: How to Install Heat-Shrink Tubing How to Install Heat-Shrink Tubing
  10. Install each power cable lug on the DC power input terminal, securing it with the nut (see Figure 60). 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.

  11. Install the plastic cable cover over each set of power cables by using the Phillips (+) screwdriver, number 2, to tighten the screw.
  12. 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 61 and Figure 62).

  13. Unscrew the captive screw in the counterclockwise direction by using the Phillips (+) screwdriver, number 1.
  14. Rotate the captive screw away from the faceplate of the power supply to release the latch.
  15. 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 63 and Figure 64).
  16. Push the captive screw into the power supply faceplate. Ensure that the screw is seated inside the corresponding hole on the faceplate.
  17. 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.

  18. 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 65 and Figure 66.

    Warning:

    Ensure that the power cords do not block access to router components or drape where people can trip on them.
  19. Set the three dip switches to select the inputs and confirm whether the power supply is running at 2200 W, 2750 W, 4400 W, or 5500 W. See Table 3 and Figure 67.

    Set both enable routers to the on position when using both source inputs. When not using source redundancy, set the unused source to the O (off) position. The LED turns red and indicates an error if a source input is not in use and the enable router is | (on).
