Install and Remove PTX10004 Power System Components

The PTX10004 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 a PTX10004, read the following sections. All power supply models are hot-insertable and hot-removeable field-replaceable units (FRUs). You can install up to three 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.

Note:

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

Install a JNP10K-PWR-AC2 Power Supply

CAUTION:

Use the same type of power supply in all slots. Do not mix power supply models in a production 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.

Warning:

Protect yourself from severe burns by wearing heat-protective gloves when removing a running JNP10K-PWR-AC2 power supply from the chassis. The power supply can reach temperatures between 158°F to 176°F (70°C to 80°C) under running conditions.

Before you install a JNP10K-PWR-AC2 power supply in the chassis:

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

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

  • If the AC or DC power source outlets have a power switch, set them to the off (O) position. Ensure that you have the following parts and tools available to install the JNP10K-PWR-AC2 power supply:

    • Electrostatic discharge (ESD) grounding strap

    • Phillips (+) screwdriver, number 1

    • Power cables appropriate for your geographical location (for low-voltage installations) or input amperage (for high-voltage installations). See PTX10004 Power Cable Specifications. HVAC and HVDC connectors and lugs must be installed by a qualified electrician before installation.

To install a JNP10K-PWR-AC2 power supply in a PTX10004:

  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 PSU2 on the rear of the PTX10004 (see Figure 1).
    Figure 1: ESD Point on the Rear of the PTX10004ESD Point on the Rear of the PTX10004
      1
    ESD point
     
  2. Taking care not to touch power supply 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 that the power switch is set to the standby (O) position. This switch turns off the output voltage; it doesn’t interrupt input power.
  5. Unscrew the captive screw in the counterclockwise direction by using the Phillips (+) screwdriver, number 1.
  6. 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 5 (top to bottom) on a PTX10004.

  7. Using both hands, place the power supply in the power supply slot on the rear of the system. Slide the power supply straight into the chassis until the power supply is fully seated in the slot. Ensure that the power supply faceplate is flush with any adjacent power supply faceplates or power supply covers (see Figure 2).
    Figure 2: Install a JNP10K-PWR-AC2Install a JNP10K-PWR-AC2
  8. Push the captive screw into the power supply faceplate. Ensure that the screw is seated inside the corresponding hole on the faceplate.
  9. 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.
  10. Attach each power cable to a dedicated power source (A and B). The JNP10K-PWR-AC2 only requires that each power supply be connected to a separate source.
  11. For each power cable, insert the end of the cable with the Anderson connector into the JNP10K-PWR-AC2 power supply. The connector snaps and locks the cable into position.
    Warning:

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

  12. If the AC or DC power source outlets have a power switch, set them to the on (|) position.
  13. Set the three DIP switches to set the inputs and whether the power supply is running at 3000 W, 5000 W, or 5500 W. See Table 1.

    Set both switch 1 and switch 2 to the on position when using both power source inputs; power is shared. When not using source redundancy, set the unused source to the off (O) position. The LED turns red and indicates an error if a source input is not in use and the DIP switch is on (|).

    CAUTION:

    Do not bump the output connections. If the connection hits a solid object, it could damage the power supply.

  9. Place the JNP10K-PWR-AC2 power supply on an antistatic surface to completely cool before placing the power supply in an antistatic bag for storage.
  10. Install the replacement JNP10K-PWR-AC2 power supply.
    CAUTION:

    Use the same type of power supply in all slots. Do not mix power supply models in a production chassis.

Install a JNP10K-PWR-DC2 Power Supply

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

  • Ensure that you follow 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 JNP10K-PWR-DC2 power supply from the chassis. JNP10K-PWR-DC2 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:

    Use the same type of power supply in all slots. Do not mix power supply models in a production chassis.

    CAUTION:

    To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must connect the PTX10004 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 PTX10004 router to ground using a separate grounding conductor, see Connect the PTX10004 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 that 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. 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 a PTX10004:

  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 5 on the rear of the PTX10004 (see Figure 5).

  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 that the power switch is set to the standby (O) position. This switch turns off the output voltage; it doesn’t 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 6).
    Figure 6: 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. Also ensure that the cable leads don’t become active while you connect 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:

    • INPUT A0: : RTN –48V/–60V

    • INPUT B0: : RTN –48V/–60V

    • INPUT A1: : RTN –48V/–60V

    • 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 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. See Figure 7.

    Figure 7: JNP10K-PWR-DC2 Input Terminal MarkingJNP10K-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.

  9. Install each power cable lug on the DC power input terminal, securing it with the nut (see Figure 8). Apply between 24 lb-in. (2.7 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 8: 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. Unscrew the captive screw in the counterclockwise direction by using the Phillips (+) screwdriver, number 1.
  12. Rotate the captive screw away from the faceplate of the power supply to release the latch.
  13. 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. (See Figure 9).
  14. Push the captive screw into the power supply faceplate. Ensure that the screw is seated inside the corresponding hole on the faceplate.
  15. 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.
    Figure 9: Install a JNP10K-PWR-DC2 in a PTX10004Install a JNP10K-PWR-DC2 in a PTX10004
  16. Route INP1 cables to a power source and INP2 to another power source. The JNP10K-PWR-DC2 shares power, so if power dips on one input, the power supply is able to load-balance internally.
    Warning:

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

  17. Set the three DIP switches to indicate the number of input sources and to indicate high or low power. See Table 2 and Figure 10.

    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.
