Maintaining the PTX10003 Power Supplies

 

The power supplies in a PTX10003 are hot-removable and hot-insertable field-replaceable units; You can remove and replace them without powering off the PTX10003 or disrupting routing functions.

Caution

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

Replacing an AC/HVDC Power Supply in the PTX10003

Warning

Turn off the power source before disconnecting the power cord to prevent damage to the power connector contact.

Warning

If you need to replace all the power supplies installed in your PTX10003, you must power off the PTX10003 before removing the power supplies. See Powering Off the PTX10003.

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.

Caution

The AC/HVDC power supply you are installing must use the same airflow direction as the fan trays installed in the router. Labels on the power supply handle indicate the direction of airflow. See PTX10003 Cooling System Description and Airflow.

Caution

Before you replace a power supply in a PTX10003, ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage (see Prevention of Electrostatic Discharge Damage).

Here’s the parts and tools you’ll need to replace a power supply:

  • ESD grounding strap (provided)

  • Antistatic bag or an antistatic mat (not provided)

  • (For a DC power supply) Phillips (+) screwdriver, number 2 (not provided)

  1. Remove the AC/HVDC Power Supply from the PTX10003

  2. Install the AC/HVDC Power Supply in the PTX10003

Remove the AC/HVDC Power Supply from the PTX10003

  1. Place the antistatic bag or the antistatic mat on a flat, stable surface.
  2. Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end of the strap to the ESD point on the device.
  3. Disconnect power to the PTX10003 power supply you are going to replace. If the AC input power source outlet has a power switch, set it to the off (O) position. If the AC input 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.
  4. Remove the power cord from the power supply by pressing in the locking button on the side of the power connector and gently pulling the connector out of the power supply faceplate. Refer to Figure 1.

  5. Slide the ejector lever on the power supply toward the orange handle until it stops.
  6. 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. See Figure 2 and Figure 3.

  7. Place the power supply in the antistatic bag or on the antistatic mat placed on a flat, stable surface.
  8. Install a new power supply within one minute of removing the old one.

Caution

Install 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.

  1. Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end of the strap to the ESD point on the device.
  2. If the power supply has protective plastic wrap, peel and remove the plastic wrap from all four sides of the power supply.
  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 field replaceable units (FRU) panel of the PTX10003 and slide it in until it is fully seated and the ejector lever slides into place. See Figure 4 and Figure 5.

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.

Replacing an DC Power Supply in the PTX10003

Warning

Turn off the circuit breaker for the DC power source before disconnecting the power cord from the power supply. Unplugging an DC connection while the power supply is powered up may damage the electrical connectors.

Warning

If you need to replace all the power supplies installed in your PTX10003, you must power off the PTX10003 before removing the power supplies. See Powering Off the PTX10003.

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.

Caution

  2. Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end of the strap to the ESD point on the device.
  3. Turn off the circuit breaker for the power feed to the power supply that you are replacing. Be sure the LEDs turn off on the power supply that you are removing.
  4. Loosen the thumb screws for the power cable. Gently pull out the female end of the power plug connected to the power supply faceplate.
  5. Disconnect a connector for the power cables or release each of three cables from the power supply (requires a standard screw driver).
  6. Grasp the power supply handle while pressing the release latch towards the power supply handle.
  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. See Figure 6and Figure 7.
