Upgrading to 3D SIBs in an Offline Switch-Fabric Chassis

 

This procedure is required to upgrade a TX Matrix Plus Router running Junos OS Release 13.1 or later. To upgrade to 3D SIBs with Junos OS Release 13.2 or later, see Upgrading an Operational TX Matrix Plus Routing Matrix to 3D SIBs.

  1. Upgrading the Junos OS Release

  2. Powering Off the TX Matrix Plus Router and Line-Card Chassis

  3. Upgrading the Switch-Fabric Chassis Components

  4. Setting the Switch-Fabric Chassis Configuration Size and Chassis ID

  5. Powering On the TX Matrix Plus Router

  6. Verifying That the 3D SIBs Are Operating Properly

  7. Connecting the Switching Plane Cables to the TX Matrix Plus Router

Upgrading the Junos OS Release

Offline upgrade to a TX Matrix Plus with 3D SIBs requires the following:

  • Junos OS Release 13.1 or later. 64-bit Junos is required.

  • The TX Matrix Plus router and line-card chassis must each contain two host subsystems. All host subsystems must be running the same Junos OS Release. This is a requirement for graceful switchover.

    Note

    The Junos OS Release 13.1 does not support In-service software upgrade (ISSU) for the TX Matrix Plus router or line-card chassis (LCC).

To upgrade the software, you use CLI commands to copy a set of software images over the network to memory storage on the Routing Engine. The Junos OS set consists of several images provided in individual packages or as a bundle. You normally upgrade all packages simultaneously.

To upgrade the software:

  1. Upgrade the Junos OS on the TX Matrix Plus router and attached line-card chassis to 64-bit Junos OS Release 13.1 or later.
  2. After you are satisfied that the new packages are successfully installed and running, issue the request system snapshot all-chassis command to back up the new software.

    For more information, see request system snapshot.

Powering Off the TX Matrix Plus Router and Line-Card Chassis

To power off the TX Matrix Plus router and connected line-card chassis (LCC):

  1. On an external management device connected to the Routing Engine, issue the request system halt all-chassis both-routing-engines operational mode command. The command shuts down the Routing Engines cleanly, so their state information is preserved. (If the TX Matrix Plus router contains only one Routing Engine, issue the request system halt command.) For more information about the command, see request system halt..
    user@host> request system halt all-chassis both-routing-engines

    Wait until a message appears on the console confirming that the operating system has halted.

  2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  3. Switch the circuit breakers on each power supply faceplate to the off position (O).

Upgrading the Switch-Fabric Chassis Components

To upgrade the switch-fabric chassis components:

  1. Upgrade the TX Matrix Plus left front air filter cover.

    See Upgrading the TX Matrix Plus Left Front Air Filter Cover.

  2. Upgrade the TX Matrix Plus F2-S SIBs.

    See Upgrading to TX Matrix Plus TXP-F2S-3D SIBs.

  3. Upgrade the TX Matrix Plus F13 SIBs.

    See Upgrading to TX Matrix Plus TXP-F13-3D SIBs.

Setting the Switch-Fabric Chassis Configuration Size and Chassis ID

Before powering on the TX Matrix Plus router again , change the CONFIG SIZE from 1 to 3. To set the CONFIG SIZE to 3:

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  2. Using a Phillips (+) screwdriver, number 2 loosen the screw for the cover over the SFC CHASSIS NUMBER and CONFIG SIZE switches.
  3. Verify that the SFC CHASSIS NUMBER switch is 00.
  4. Set the CONFIG SIZE switch to 3 for the for the TXP-T1600-3D configuration, TXP-T4000-3D configuration, and TXP-Mixed-LCC-3D configuration..
  5. Close the cover over the SFC CHASSIS NUMBER and CONFIG SIZE switches.
  6. Using a Phillips (+) screwdriver, number 2, tighten the screw for the cover over the SFC CHASSIS NUMBER and CONFIG SIZE switches.

Powering On the TX Matrix Plus Router

To power on the router:

  1. Verify that the power supplies are fully inserted in the chassis and that the captive screws and ejector handles on the faceplates are tightened.
  2. Verify that the source power cables are connected to the appropriate terminal: the positive (+) source cable to the return terminal (labeled RTN) and the negative (–) source cable to the input terminal (labeled –48V).
  3. Verify that an external management device is connected to one of the Routing Engine ports on the TXP-CB (AUX or CONSOLE). Note

    The management Ethernet port labeled ETHERNET on the TX-CB is not available until after the initial TX Matrix Plus router software configuration. You can monitor the startup process during the initial installation using devices connected to the AUX or CONSOLE ports.

  4. Verify that the SFC CHASSIS NUMBER and CONFIG SIZE switches are set correctly. See Verifying the Configuration Size and Switch-Fabric Chassis Number Settings.
  5. Turn on the power to the external management device.
  6. Switch on the customer site circuit breakers to provide voltage to the DC power source cables.
  7. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  8. Verify that the INPUT PRESENT LEDs on the power supply faceplate are lit steadily green, indicating that the inputs are receiving power. Warning

    If any of the INPUT PRESENT LEDs are red, indicating that the power is reversed, switch off the customer site circuit breakers immediately. Correct the cabling and verify that all INPUT PRESENT LEDs are green before proceeding with the procedure.

  9. Switch the circuit breakers on one of the power supplies to the on position (|).
  10. Verify that the PWR ON LEDs on the power supply faceplate are lit steadily. The PWR ON LEDs blink momentarily, then light steadily to indicate that the circuit breakers are on.Note

    After a power supply is powered on, it can take up to 60 seconds for status indicators—such as the LEDs on the power supply, the command output displays, and messages on the LCD on the craft interface—to indicate that the power supply is functioning normally. Ignore error indicators that appear during the first 60 seconds.

  11. Verify that the PEM OK LED on the power supply faceplate is lit steadily and that the FAULT LED is off, indicating that the power supply is correctly installed and is functioning properly.Note

    If the PEM OK LED does not light steadily or the FAULT LED is lit, see Troubleshooting the TX Matrix Plus Power System.

  12. On the external management device connected to the Routing Engine, monitor the startup process to verify that the system has booted properly.Note

    After powering on a power supply, wait at least 60 seconds before turning it off.

Verifying That the 3D SIBs Are Operating Properly

  1. Verify that the 3D SIBs are displayed in the output of the show chassis hardware models sfc 0 command.
    user@host> show chassis hardware models sfc 0
  2. Verify that the green OK LED on the faceplate of the SIBs are lit steadily.
  3. Issue the show chassis sibs command to verify that the TXP-F2S-3D SIBs and TXP-F13-3D SIBs are online and functioning normally:
    user@host>show chassis sibs

Connecting the Switching Plane Cables to the TX Matrix Plus Router

Note

Do not connect the switching plane cables to the line-card chassis at this time.
