Removing a CompactFlash Card in a T1600 C1800 Routing Engine

1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
2. Determine whether the host subsystem is functioning as the master or as the backup, using one of these methods:
   • Check the Routing Engine 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 CLI command. The master Routing Engine is designated Master in the Current state field:
     user@host> show chassis routing-engine

     Routing Engine status:   
       Slot 0:
         Current state                 Master
     ...
      

3. If the host subsystem is functioning as the master, switch it to backup using the request chassis routing-engine master switch command.
4. From the master Routing Engine, issue the request system power-off other-routing-engine to power down the backup Routing Engine.
5. Verify that the Online, DISK1, and CF LEDs on the backup Routing Engine faceplate are off.
6. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
7. 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).

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

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

Installing a CompactFlash Card in a T1600 C1800 Routing Engine

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 and tighten the screws on the corners of the cover to secure it to the Routing Engine (using a Phillips (+) screwdriver, number 2).
6. From the master Routing Engine, issue the request system power-on 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 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 to the CompactFlash card.

Note: For more information about the commands for this procedure, see the Junos OS System Basics and Services Command Reference

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 command to copy the currently running and active file system partitions on the router to standby partitions on the CompactFlash card.
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. The CompactFlash card will now be the primary boot device.
4. Issue the show system boot-messages command to verify that boot order is correct. The output lists the devices mounted. The CompactFlash card is located at ad0.
