Maintaining the PTX3000 Host Subsystem

Maintaining the PTX3000 Routing Engines

Purpose

For optimum performance, verify the condition of the Routing Engines.

Action

On a regular basis:

  • Check the LEDs on the Routing Engine. During normal operation, the ONLINE LED on each Routing Engine is lit green, indicating that the Routing Engine is functional.

  • Issue the show chassis routing-engine command to verify that the Routing Engines are operating properly.

Replacing a PTX3000 C2600 Routing Engine

Taking the PTX3000 Host Subsystem Offline

Before you replace a Control Board or a Routing Engine, you must take the host subsystem offline. The host subsystem is taken offline and brought online as a unit. Before you take a host subsystem offline, but be sure that you are aware of how this will affect the PTX3000.

To take a host subsystem offline:

  1. Determine whether the host subsystem is functioning as the primary or as the backup, by issuing the show chassis routing-engine command. The primary Routing Engine is designated Master in the Current state field.
  2. If the host subsystem is functioning as the primary, switch it to be the backup by using the following CLI command:

    If the Routing Engines are running the same Junos OS Release and are configured for graceful switchover, the standby Routing Engine immediately assumes Routing Engine functions and there is no interruption to packet forwarding. Otherwise, packet forwarding halts while the standby Routing Engine becomes the primary and the Packet Forwarding Engine components reset and connect to the new primary Routing Engine. For information about configuring graceful switchover, see the High Availability User Guide.

    Note:

    PTX3000 performance might change if the standby Routing Engine's configuration differs from the former primary's configuration. For the most predictable performance, configure the two Routing Engines identically, except for parameters unique to a Routing Engine, such as the hostname defined at the [edit system] hierarchy level and the management interface (em0 or equivalent) defined at the [edit interfaces] hierarchy level.

    To configure Routing Engine-specific parameters and still use the same configuration on both Routing Engines, include the appropriate configuration statements under the re0 and re1 statements at the [edit groups] hierarchy level and use the apply-groups statement. For instructions, see Applying a Junos OS Configuration Group.

  3. To halt the PTX3000:
    Note:

    The request system halt command halts all Routing Engines on the control plane from which it was issued. To reboot a Routing Engine that has been halted, you must connect through the console.

    The command shuts down the Routing Engine cleanly, so its state information is preserved. For more information about the command, see request system halt.

    Note:

    The SIBs might continue forwarding traffic for approximately 5 minutes after the request system halt command has been issued.

Removing a PTX3000 Routing Engine

The PTX3000 can have one or two Routing Engines. They are located in a slot to the left of the Control Board. Each Routing Engine weighs 2.8 lb (1.3 kg).

To remove a Routing Engine (see Figure 1):

  1. If the Routing Engine to be replaced is currently functioning as the primary Routing engine, switch it to be the backup before removing it.
  2. Take the host subsystem offline. If there is only one host subsystem, taking the host subsystem offline shuts down the PTX3000.
  3. Place an electrostatic bag or antistatic mat on a flat, stable surface.
  4. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
  5. Take the host subsystem offline.
  6. Press the red tabs on the ejector handles on both sides of the Routing Engine faceplate.
  7. Flip the ejector handles outward to unseat the Routing Engine.
  8. Grasp the Routing Engine by the ejector handles and slide it about halfway out of the chassis.
  9. Place one of your hands underneath the Routing Engine to support it and slide it completely out of the chassis.
  10. Place the Routing Engine on the antistatic mat.

  3. Place one hand underneath the Routing Engine to support it. With the other hand, grasp one of the ejector handles on the faceplate.
  4. Carefully align the sides of the Routing Engine with the guides inside the opening on the Control Board.
  5. Slide the Routing Engine into the chassis until you feel resistance.
  6. Press the Routing Engine's faceplate until it engages the connectors.
  7. Press both the ejector handles inward to seat the Routing Engine.

    The Routing Engine might require several minutes to boot. If the PTX3000 is powered on and the Routing Engine's corresponding Control Board is functioning normally, the Routing Engine comes online automatically.

  8. Verify that the Routing Engine is installed correctly and functioning properly:

    • Verify that the green Online LED is lit steadily.

    • Verify the status of the Routing Engine by using the show chassis routing-engine command.

    For more information about the commands, see the Junos OS manuals.

Maintaining the PTX3000 Control Boards

Purpose

For optimum performance, verify the condition of the Control Boards.

Action

On a regular basis:

  • Look at the LEDs on the Control Board faceplates to see information about the Control Boards.

    During normal operations:

    • The green OK LED on the Control Board faceplate is lit.

    • The yellow FAIL LED on the Control Board faceplate is not lit.

  • Issue the show chassis environment cb command to verify that the Control Boards are operating properly.

    For more information about this command, see the Junos OS manuals.

Replacing a PTX3000 Control Board

The PTX3000 has two Control Boards. One Control Board is located to the right of each Routing Engine. Each Control Board weighs 3.1 lb (1.4 kg).

Taking the PTX3000 Host Subsystem Offline

Before you replace a Control Board or a Routing Engine, you must take the host subsystem offline. The host subsystem is taken offline and brought online as a unit. Be aware of how taking the host subsystem offline will affect the PTX3000.

If there is only one host subsystem, taking the host subsystem offline shuts down the PTX3000. If the Control Board to be replaced is associated with the Routing Engine currently functioning as the primary Routing Engine, switch to the backup before removing the Control Board.

CAUTION:

Before you replace a Control Board, you must take the host subsystem offline.

To take a host subsystem offline:

  1. Determine whether the host subsystem is functioning as the primary or as the backup by issuing the show chassis routing-engine command. The primary Routing Engine is designated Master in the Current state field.
  2. If the host subsystem is functioning as the primary, switch it to backup by using the following CLI command:

    If the Routing Engines are running the same Junos OS release and are configured for graceful switchover, the standby Routing Engine immediately assumes Routing Engine functions and there is no interruption to packet forwarding. Otherwise, packet forwarding halts while the standby Routing Engine becomes the primary and the Packet Forwarding Engine components reset and connect to the new primary Routing Engine. For information about configuring graceful switchover, see the High Availability User Guide.

    Note:

    PTX3000 performance might change if the standby Routing Engine's configuration differs from the former primary's configuration. For the most predictable performance, configure the two Routing Engines identically, except for parameters unique to a Routing Engine, such as the hostname defined at the [edit system] hierarchy level and the management interface (em0 or equivalent) defined at the [edit interfaces] hierarchy level.

    To configure Routing Engine-specific parameters and still use the same configuration on both Routing Engines, include the appropriate configuration statements under the re0 and re1 statements at the [edit groups] hierarchy level and use the apply-groups statement. For instructions, see Applying a Junos OS Configuration Group.

  3. To halt the PTX3000:
    Note:

    The request system halt command halts all Routing Engines on the control plane from which it was issued. To reboot a Routing Engine that has been halted, you must connect through the console.

    The command shuts down the Routing Engine cleanly, so its state information is preserved. For more information about the command, see request system halt.

    Note:

    The SIBs might continue forwarding traffic for approximately 5 minutes after the request system halt command has been issued.
