Preparing to Replace a CompactFlash Card in a T1600 C1800 Routing Engine

To prepare to replace a CompactFlash card in a T1600 RE-C1800:

  1. Determine whether the host subsystem is functioning as the master or as the backup, using one of these methods:
    • For standalone T1600 routers:

      • Check the Host Subsystem LEDs on the craft interface. If the green MASTER LED is lit, the corresponding host subsystem is functioning as the master.

      • Check the MASTER LED on the control board. If the blue MASTER LED is lit, the host subsystem is functioning as the master.

      • Issue the following command:

        user@host> show chassis routing-engine

        In this example, the Routing Engine in slot 0 is designated Master in the Current state field

    • For T1600 routers in a routing matrix, verify that the master Routing Engine for all routers in the routing matrix are in the same slot.

      To determine whether the host subsystems are functioning as the master or as the backup:

      • Issue the show chassis routing-engine CLI command from the TX Matrix Plus router.

        The master Routing Engine is designated Master in the Current state field. In this example, the Master Routing Engine is in Slot 0 for both sfc0-re0 and lcc0-re0.

        user@host> show chassis routing-engine

        In this example, the Master Routing Engine is in Slot 0 for sfc0-re0 but Slot 1 for lcc0-re0.

        user@host> show chassis routing-engine

      If the master host subsystem for any T1600 router lcc in a routing matrix is in a different slot from the master host subsystem for the TX Matrix Plus router sfc, use the request chassis routing-engine master switch lcc command to correct the problem.

      Note

      This command switches the master routing engine in the T1600 router.

      user@host> request chassis routing-engine master switch lcc 0
  2. If the host subsystem is functioning as the master, switch it to backup.
    • For a standalone T1600 router, issue the request chassis routing-engine master switch command.

    • For a T1600 router in a routing matrix, issue the request chassis routing-engine master switch all-chassis command from the TX Matrix Plus router.

  3. From the master Routing Engine, power down the backup Routing Engine.
    • For a standalone T1600 router, issue the request system power-off other-routing-engine command.

    • For a T1600 router in a routing matrix, issue the request system power-off lcc number other-routing-engine command from the TX Matrix Plus router.

      Replace number with a value from 0 through 3 for the line-card chassis (lcc).

Removing a CompactFlash Card in a T1600 C1800 Routing Engine

The CompactFlash card is located in the slot labeled CF on the Routing Engine faceplate. To remove the CompactFlash card:

  1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
  2. Verify that the Online, DISK1, and CF LEDs on the backup Routing Engine faceplate are off.
  3. 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. Using a Phillips (+) screwdriver, number 2, loosen the captive screws on the corners of the cover over the Routing Engine slots.
  5. Remove the cover from the Routing Engine slots.Caution

    Do not remove the cover if any of the LEDs are lit.

  6. Press the eject button on the right side of the CompactFlash card slot to release the CompactFlash card.
  7. The CompactFlash card pops partially out of the slot. Grasp the card and pull it completely out of the slot.
  8. Place the CompactFlash card on the antistatic mat.

Installing a CompactFlash Card in a T1600 C1800 Routing Engine

To install a CompactFlash card:

  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. Remove the cover from the Routing Engine slots by loosening the captive screws on the corners of the cover (using a Phillips (+) screwdriver, number 2).
  3. Insert the CompactFlash card into the CompactFlash card slot on the Routing Engine, with the logo facing up.Caution

    Be sure to insert the CompactFlash card with the label facing up. Inserting the CompactFlash card incorrectly might damage the Routing Engine.

  4. Press the card firmly all the way into the slot.
  5. Reinstall the Routing Engine cover. Using a Phillips (+) screwdriver, number 2, tighten the screws on the corners of the cover to secure it to the Routing Engine.
  6. From the master Routing Engine, power on the Routing Engine.
    • For a standalone T1600 router, issue the request system power-on other-routing-engine command.

    • For a T1600 router in a routing matrix, issue the request system power-on lcc number other-routing-engine command from the TX Matrix Plus router.

      Replace number with a value from 0 through 3 for the line-card chassis (lcc).

    Note

    After you replace a CompactFlash card, the Routing Engine boots from the solid-state disk (SSD). You may get an error message and be prompted for a keystroke. After you press the keystroke, it might take up to 10 minutes for the Routing Engine to reset and for the router to boot from the SSD.

Copying Junos OS to the CompactFlash Card in a T1600 C1800 Routing Engine

After installing the CompactFlash card for the first time, you must copy the software from the Routing Engine's solid-state disk (SSD) to the CompactFlash card.

To copy software to the CompactFlash card:

  1. On the console or other management device connected to the Routing Engine, enter CLI operational mode and copy the currently running and active file system partitions on the router to standby partitions on the CompactFlash card.
    • On standalone T1600 routers, issue the request system snapshot partition command.

    • On T1600 routers in a routing matrix, issue the request system snapshot partition lcc number command.

      Replace number with a value from 0 through 3 for the line-card chassis (lcc).

  2. Wait until a message appears on the console confirming that the snapshot partition procedure is complete.
  3. Issue the request system reboot command to reboot the router's software.
  4. Issue the show system boot-messages command to verify that the CompactFlash card is listed as the primary boot device. The output lists the devices mounted. The CompactFlash card is located at ad0.
