Powering Off the PTX10003

 
  • Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage. See Prevention of Electrostatic Discharge Damage.

  • Ensure you do not need to route traffic through the PTX10003.

  • Ensure you have the following parts and tools available to power off the PTX10003:

    • An ESD grounding strap

    • An external management device such as a PC

    • An RJ-45 to DB-9 rollover cable to connect the external management device to the console port

Powering Off the AC-Powered PTX10003

  1. Connect to the router by using one of the following methods:
  2. Shut down Junos OS Evolved from the external management device by issuing the request system shutdown halt operational mode CLI command. This command shuts down Junos OS Evolved gracefully and preserves system state information. A message appears on the console, confirming that the operating system has halted.
    user@host> request system shutdown halt
    Halt the system ? [yes,no] (no) yes

    You see the following output (or something similar) after entering the command:

    Caution

    The final output of any version of the request system shutdown halt command is the "The operating system has halted." Although traffic and the operating system have stopped, the PTX10003 power supply LEDs remain lit and a fan module continues to run. Wait at least 60 seconds after first seeing this message before continuing with this procedure.

  3. 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.
  4. Disconnect power to the PTX10003. 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.
  5. Remove the power source cable from the power supply by pushing in the latch on the side of the power connector and gently pulling out the power plug from the power supply.
  6. Uncable the device before removing it from the rack.

Powering Off the DC-Powered PTX10003

  1. Connect to the router by using one of the following methods:
  2. Shut down Junos OS from the external management device by issuing the request system shutdown halt operational mode CLI command. This command shuts down Junos OS gracefully and preserves system state information. A message appears on the console, confirming that the operating system has halted.
    user@host> request system shutdown halt
    Halt the system ? [yes,no] (no) yes

    You see the following output (or something similar) after entering the command:

    Caution

    The final output of any version of the request system shutdown halt command is the “The operating system has halted.” Although traffic and the operating system have stopped, the PTX10003 power supply LEDs remain lit and a fan module continues to run. Wait at least 60 seconds after first seeing this message before following continuing with this procedure.

  3. 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.
  4. Turn off the circuit breaker for the DC power source.Caution

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

  5. Loosen the thumb screws for the power cable.
  6. Disconnect a connector for the power cables or release each of three cables from the power supply (requires a standard screw driver).
  7. Gently pull out the female end of the power cable connected to the power supply.
  8. Uncable the device before removing it from the rack.
