Maintaining the PTX1000 Power Supplies
Removing a Power Supply from the PTX1000
Before you remove a power supply from a PTX1000, 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
The power supplies in a PTX1000 are hot-removable and hot-insertable field-replaceable units (FRUs)—you can remove and replace them without powering off the PTX1000 or disrupting routing functions.
Replace the power supply within 30 seconds of removal to prevent chassis overheating. Before removing the power supply, ensure you have a replacement power supply available.
Do not mix AC and DC power supplies in the same chassis.

Before you install a power supply in a PTX1000, ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage (see Prevention of Electrostatic Discharge Damage).
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.

To install a power supply in a PTX1000 (see Figure 2):
- Taking care not to touch power supply components, pins, leads, or solder connections, remove the power supply from its bag.
- Using both hands, place the power supply in the power supply slot on the FRU panel of the PTX1000 and slide it in until it is fully seated and the locking lever slides into place.

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