Preparing to Replace a CompactFlash Card in a TX Matrix C1800 Routing Engine

To prepare to replace a CompactFlash card in a TX Matrix C1800 Routing Engine:

  1. Issue the show chassis routing-engine CLI command to determine the master Routing Engine for all routers in the routing matrix. The master Routing Engine is designated Master in the Current state field. Note

    The master Routing Engine for all routers in the routing matrix must be in the same slot.

    In this example, the Master Routing Engine is in Slot 0 for both scc0-re0 and lcc0-re0.

    user@host> show chassis routing-engine

    In this example, the Master Routing Engine is in Slot 0 for scc0-re0 but Slot 1 for lcc0-re0.

    user@host> show chassis routing-engine
  2. If the host subsystem is functioning as the master, switch it to backup using the request chassis routing-engine master switch all-chassis command.
  3. From the master Routing Engine, issue the request system power-off scc 0 other-routing-engine to power down the backup Routing Engine in the TX.

Removing a CompactFlash Card in a TX Matrix C1800 Routing Engine

The CompactFlash card is located in the slot labeled CF on the Routing Engine faceplate. To remove the CompactFlash card from a C1800 Routing Engine in a TX Matrix router (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 TX Matrix 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 right.Caution

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

  4. Press the card firmly all the way into the CF 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, issue the request system power-on sfc 0 other-routing-engine command to power on the Routing Engine.Note

    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 solid-state disk.

Copying the Junos OS to the CompactFlash Card in a TX Matrix Routing Engine

After installing the CompactFlash card for the first time, you must copy the software from the Routing Engine's solid-state disk 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 issue the request system snapshot partition scc 0 command to copy the currently running and active file system partitions on the router to standby partitions on the CompactFlash card. For more information, see request system snapshot.
  2. Wait until a message appears on the console confirming that the snapshot partition procedure is complete.
  3. Issue the request system reboot scc 0 command to reboot the router's software. For more information, see request system reboot.
  4. Issue the show system boot-messages scc 0 command to verify that the CompactFlash card is the primary boot device. The output lists the devices mounted. The CompactFlash card is located at ad0. For more information, see show system boot-messages.
