Maintaining the PTX10002-60C Power Supplies

 

Removing a Power Supply from the PTX10002-60C

The power supplies in a PTX10002-60C are hot-removable and hot-insertable field-replaceable units (FRUs)—you can remove and replace them without powering off the PTX10002-60C or disrupting routing functions.

Caution

Replace the power supply within 1 minute of removal to prevent chassis overheating. Before removing the power supply, ensure you have a replacement power supply available.

Before you remove a power supply from a PTX10002-60C, ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage (see Prevention of Electrostatic Discharge Damage).

Ensure that you have the following parts and tools available:

  • ESD grounding strap

  • Antistatic bag or an antistatic mat

  • Phillips (+) screwdriver, number 2 (DC power supply)

If you are removing a redundant power supply and do not plan to replace it with another immediately, have a power supply cover for the opening.

Caution

Do not mix AC and DC power supplies in the same chassis.

To remove a power supply from a PTX10002-60C (see Figure 1):

  1. Place the antistatic bag or the antistatic mat on a flat, stable surface.
  2. To prevent damage to the equipment caused by static discharge, attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  3. Disconnect power to the PTX10002-60C:

    • AC power supply—If the AC power source outlet has a power switch, set it to the off (O) position. If the AC power source outlet does not have a power switch, gently pull out the plug end of the power cord connected to the power source outlet.

    • DC power supply—Switch the circuit breaker on the panel board that services the DC circuit to the off position.

    Note

    If you need to remove all the power supplies installed in your PTX10002-60C, you must power off the PTX10002-60C before removing the power supplies. See Powering Off the PTX10002-60C.

  4. Remove the power source cable from the power supply faceplate:

    • AC power supply—Remove the power cord from the power supply faceplate by detaching the power cord retainer and gently pulling out the socket end of the power plug connected to the power supply faceplate.

    • DC power supply—Loosen the thumb screws for the power cable. Gently pull out the socket end of the power plug connected to the power supply faceplate.

  5. Slide the locking lever toward the handle until it stops.
  6. Grasp the power supply handle and pull firmly to slide the power supply halfway out of the chassis. See Figure 1.
  7. Place one hand under the power supply to support it and slide it completely out of the chassis. Take care not to touch power supply components, pins, leads, or solder connections.

  8. Place the power supply in the antistatic bag or on the antistatic mat placed on a flat, stable surface.
  9. Either replace with another power supply or insert a PSU blank cover (PTX10002-PWR-BLNK). Refer to Figure 2

Installing a Power Supply in a PTX10002-60C

The power supplies in a PTX10002-60C are hot-removable and hot-insertable field-replaceable units (FRUs)—you can remove and replace them without powering off the PTX10002-60C or disrupting routing functions.

Caution

Replace the power supply within one minute of removal to prevent chassis overheating. Before removing the power supply, ensure you have a replacement power supply available.

  • Before you install a power supply in a PTX10002-60C, ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage (see Prevention of Electrostatic Discharge Damage).

  • Ensure that the airflow direction of the power supply is the same as the chassis. Labels on the power supply handle indicate the direction of airflow. See PTX10002-60C Cooling System Description and Airflow.

  • Ensure that you have an ESD grounding strap.

  • If the power supply has protective plastic wrap, peel and remove the plastic wrap from all four sides of the power supply.

Caution

Do not mix AC and DC power supplies in the same chassis.

To install a power supply in a PTX10002-60C (see Figure 4):

  1. To prevent damage to the equipment caused by static discharge, attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  2. If the power supply is being installed in an empty slot, remove the blank cover by squeezing the finger holds and pulling the cover straight out.

  3. Taking care not to touch power supply components, pins, leads, or solder connections, remove the power supply from its bag.
  4. Using both hands, place the power supply in the power supply slot on the FRU panel of the PTX10002-60C and slide it in until it is fully seated and the locking lever slides into place.

Note

Each power supply must be connected to a dedicated power source outlet.

Note

If you have a Juniper Care service contract, register any addition, change, or upgrade of hardware components at https://www.juniper.net/customers/support/tools/updateinstallbase/ . Failure to do so can result in significant delays if you need replacement parts. This note does not apply if you replace existing components with the same type of component.
