Maintaining the PTX10001 Power Supplies

 

Removing a Power Supply from the PTX10001

The power supplies in a PTX10001 are hot-removable and hot-insertable field-replaceable units (FRUs) when the second power supply is installed and running. You can install replacement power supplies in the two slots next to the fan modules without powering off the device or disrupting the routing functions.

Before you remove a power supply from a PTX10001, 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)

Caution

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

To remove a power supply from a PTX10001 (see Figure 1):

  1. Place the antistatic bag or the antistatic mat on a flat, stable surface.
  2. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.Note

    If you need to remove all the power supplies installed in your PTX10001, you must power off the PTX10001 before removing the power supplies. See Powering Off the PTX10001.

  3. Disconnect power to the PTX10001:

    • 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 male 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.

  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 female end of the power cord connected to the power supply faceplate.

    • DC power supply—Remove the screws securing the ring lugs attached to the power source cables to the power supply using the screwdriver, and remove the power source cables from the power supply. Replace the screws on the terminals and tighten them.

  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.
  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.

  2. Taking care not to touch power supply components, pins, leads, or solder connections, remove the power supply from its bag.
  3. Using both hands, place the power supply in the power supply slot on the FRU panel of the PTX10001 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.
