Maintain the PTX10016 Power System Components

PTX10016 routers support AC, DC, high voltage alternating current (HVAC), and high voltage direct current (HVDC) power supplies. To install and remove the power supplies in the PTX10016 router, read the following sections. All power supply models are hot-removable and hot-insertable field-replaceable units (FRUs). You can install up to 10 power supplies in the rear of the chassis in the slots provided along the left side.

CAUTION:

Use the same type of power supply in all slots. Do not mix power supply models in the same chassis. The only time you are allowed to have two models concurrently running in a system is when you are in the process of swapping out all JNP10K-PWR-AC power supplies with all JNP10K-PWR-AC2 power supplies.

Note:

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

Install a JNP10K-PWR-AC Power Supply in the PTX10016 Router

Before you install a JNP10K-PWR-AC power supply in the PTX10016 router:

  • Ensure that you have followed all safety warnings and cautions.

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

    CAUTION:

    Before you remove a power supply, ensure that you have power supplies sufficient to power the router left in the chassis. See Power Requirements for PTX10016 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 over the empty slot.

  • If the AC power source outlets have a power switch, set them to the off (O) position.

  • Ensure that you have the following parts and tools available:

    • Electrostatic discharge (ESD) grounding strap (provided in the accessory kit)

    • Phillips (+) screwdriver, number 1

    • Power cords appropriate for your geographical location (See PTX10016 Power Cables Specifications.)

    • Power cord retainer clips

To install a JNP10K-PWR-AC power supply in the PTX10016 router:

  1. Wrap and fasten one end of the ESD grounding strap around your bare wrist and connect the other end of the strap to an ESD point on the chassis. There is an ESD point located next to the protective earthing terminal and below PSU 9 on the rear of the PTX10016 chassis (see Figure 1).
    Figure 1: ESD Point on the Rear of the PTX10016 Chassis ESD Point on the Rear of the PTX10016 Chassis

  2. If the power supply slot has a cover on it, insert your thumb and forefinger into the finger holes, squeeze, and pull the cover out of the slot. Save the cover for later use. See Figure 2.
    Figure 2: Remove the Power Supply Cover from the PTX10016 ChassisRemove the Power Supply Cover from the PTX10016 Chassis
  3. Taking care not to touch power supply connections, remove the power supply from its bag.
  4. Peel back and remove the protective plastic wrap that covers all four sides of the power supply.
  5. Ensure the power switch is set to the standby (O) position. This switch turns off the output voltage; it does not interrupt AC supply.
  6. Unscrew the captive screw in the counterclockwise direction by using your fingers or by using the Phillips (+) screwdriver, number 1.
  7. Rotate the captive screw away from the faceplate of the power supply to release the latch.
    Note:

    You can install the power supplies in any slot labeled PSU 0 through PSU 9 (top to bottom) on the PTX10016 router.

  8. Using both hands, place the power supply in the power supply slot on the rear of the system.
  9. 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 covers (see Figure 3).
  10. Push the captive screw into the power supply faceplate. Ensure that the screw is seated inside the corresponding hole on the faceplate.
  11. Tighten the captive screw by turning it clockwise by using your fingers or by using the Phillips (+) screwdriver, number 1. Do not overtighten—do not apply more than 7.3 lb-in (0.82 Nm) of torque to the screws. When the screw is completely tight, the latch locks into the router chassis.
    Note:

    Ensure that the ejector is fully open to avoid scratching the chassis.

    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.

    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:

    To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must connect PTX10016 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 the PTX10016 router to ground using a separate grounding conductor, see Connect the PTX10016 Router to Earth Ground.

    Note:

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

  • Ensure that you have followed all safety warnings and cautions.

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

  • Ensure that you have the following parts and tools available:

    • Electrostatic discharge (ESD) grounding strap (provided in the accessory kit)

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

      The provided Panduit LCD4-14A-L, or equivalent, terminal lugs in the PTX10016 are sized for either 4 AWG (21.1 mm2) or 6 AWG (13.3 mm2) power source cables. When using all JNP10K-PWR-DC power supplies in the chassis, the DC power source cables that you provide must be 6 AWG (13.3 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. The 4 AWG (21.1 mm²) stranded wire should be rated 75° C, or per local electrical code.

      Note:

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

  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, using the Phillips (+) screwdriver, number 2, to loosen the screws (see Figure 15).
    Figure 15: Remove the Plastic Cable Cover on a JNP10K-PWR-DC Power SupplyRemove the Plastic Cable Cover on a JNP10K-PWR-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 each power cable lug on the DC power input terminal, securing it with the nut (see Figure 16). Apply between 23 lb-in. (2.6 Nm) and 25 lb-in. (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 16: Connect the DC Power Source Cables to a JNP10K-PWR-DC Power SupplyConnect the DC Power Source Cables to a JNP10K-PWR-DC Power Supply

    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 on it, insert your thumb and forefinger into the finger holes, squeeze, and pull the cover out of the slot. Save the cover for later use (see Figure 17).

Install a JNP10K-PWR-DC2 Power Supply in the PTX10016 Router

Before you install a JNP10K-PWR-DC2 power supply in the PTX10016 router:

  • 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 (O) 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 temperatures between 158° F and 176° F (70° C to 80° C) under running conditions.

    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:

    To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must connect PTX10016 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 the PTX10016 router to ground using a separate grounding conductor, see Connect the PTX10016 Router 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:

    • Heat-protective gloves, such as welder's gloves, that can withstand temperatures up to 176° F (80° C)

    • Electrostatic discharge (ESD) grounding strap (provided in the accessory kit)

    • 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. The 4 AWG (21.1 mm²) stranded wire should be rated 75° C, or per local electrical code. 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 the PTX10016 router:

  1. Wrap and fasten one end of the ESD grounding strap around your bare wrist and connect the other end of the strap to an ESD point on the chassis. There is an ESD point located next to the protective earthing terminal and below PSU 9 on the rear of the PTX10016 chassis (see Figure 23).
    Figure 23: ESD Point on the Rear of the PTX10016 Chassis ESD Point on the Rear of the PTX10016 Chassis

    ESD point
     
  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: Remove the Plastic Cable Cover on a JNP10K-PWR-DC2 Power SupplyRemove 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.

    The JNP10K-PWR-DC2 power supply is the equivalent of two power supplies in a single housing. Each JNP10K-PWR-DC2 has four independent sets of DC power input terminals:

    • A0: INPUT A0 RTN –48V/–60V

    • B0: INPUT B0 RTN –48V/–60V

    • A1: INPUT A1 RTN –48V/–60V

    • B1: INPUT B1 RTN –48V/–60V

    We recommend source redundancy (source A and source B) to all inputs to ensure reliability of the system. If you do not have two power sources available, then having two feeds from the same source provides power distribution reliability because there are two independent power distribution from the source to the system.

    Figure 25: JNP10K-PWR-DC2 Input Terminal Marking
    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.

    We recommend source redundancy (source A and source B) to all inputs to ensure reliability of the system. If you do not have two power sources available, then having two feeds from the same source provides power distribution reliability because there are two independent power distribution from the source to the system.

  9. Install each power cable lug on the DC power input terminal, securing it with the nut (see Figure 26). Apply between 23 lb-in. (2.6 Nm) and 25 lb-in. (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.

    Figure 26: Connect the DC Power Source Cables to a JNP10K-PWR-DC2 Power SupplyConnect the DC Power Source Cables to a JNP10K-PWR-DC2 Power Supply
  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 on it, insert your thumb and forefinger into the finger holes, squeeze, and pull the cover out of the slot. Save the cover for later use (see Figure 27).
    Figure 27: Remove the Power Supply Cover from the PTX10016 ChassisRemove the Power Supply Cover from the PTX10016 Chassis
  12. Unscrew the captive screw in the counterclockwise direction by using your fingers or 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 28).
  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 your fingers or by using the Phillips (+) screwdriver, number 1. Do not overtighten—do not apply more than 7.3 lb-in (0.82 Nm) of torque to the screws. When the screw is completely tight, the latch locks into the router chassis.

  17. Route input A0 and A1 cables to a power source and input B0 and B1 cables to another power source. You must connect each input to a dedicated power distribution and protection. The JNP10K-PWR-DC shares power, so if power dips on one input, the power supply is able to load-balance internally. See Figure 29.

    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 indicate the number of input sources and to indicate high or low power. See Table 2 and Figure 30.

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