Preparing to Replace a CompactFlash Card in a T640 RE-C180 Routing Engine

To prepare to replace a CompactFlash card in a T60 RE-C1800 Routing Engine:

  1. Determine whether the host subsystem is functioning as the master or as the backup, using one of these methods:
    • 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 show chassis routing-engine command:

      user@host> show chassis routing-engine

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

  2. If the host subsystem is functioning as the master, switch it to backup. Issue the request chassis routing-engine master switch command.
  3. From the master Routing Engine, power down the backup Routing Engine. Issue the request system power-off other-routing-engine command.

Removing a CompactFlash Card in a T640 RE-C1800 Routing Engine

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

To remove the CompactFlash card (see Figure 1):

  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 T640 RE-C1800 Routing Engine

To install a CompactFlash card (see Figure 2):

  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 router, issue the request system power-on other-routing-engine command.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 the Junos OS to the CompactFlash Card in a T640 RE-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.

Note

For more information about the commands for this procedure, see request system snapshot, request system reboot, and show system boot-messages.

To copy software to the CompactFlash card:

  1. On the console or other management device connected to the Routing Engine, enter CLI operational mode.
  2. Copy the currently running and active file system partitions on the router to standby partitions on the CompactFlash card. Issue the request system snapshot partition command.
  3. Wait until a message appears on the console confirming that the snapshot partition procedure is complete.
  4. Issue the request system reboot command to reboot the router's software.
  5. 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.
