Packing the M320 Router for Shipment

To pack the router for shipment:

1. Retrieve the shipping crate and packing materials in which the router was originally shipped. If you do not have these materials, contact your Juniper Networks representative about approved packaging materials.
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. On the console or other management device connected to the master Routing Engine, enter CLI operational mode and issue the following command to shut down the router software. (If two Routing Engines are installed, also issue the command on the backup Routing Engine.)
   user@host> request system halt

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

   For more information about the command, see the Junos OS System Basics and Services Command Reference.

   Note: The SIB might continue forwarding traffic for approximately 5 minutes after the request system halt command has been issued.

4. Shut down power to the router by pressing the power switch for all power supplies to the off (O) position. On both AC and DC power supplies, the switch is located on the power supply faceplate.
5. Disconnect power from the router. For instructions, see Replacing an M320 AC Power Supply Cord or Replacing an M320 DC Power Supply Cable.
6. Remove the cables that connect to all external devices. For instructions, see Removing an M320 PIC Cable, Removing an M320 Console or Auxiliary Cable, Replacing the M320 Alarm Relay Wires, and Replacing an M320 Management Ethernet Cable.
7. Remove all Field Replaceable Units (FRUs) from the router.

   See Removing M320 Components from the Chassis.

8. Remove the router from the rack:
   • If you are using a mechanical lift, place the lift platform under the router, unscrew and remove the mounting screws from the rack, and move the router to the shipping crate.
   • If you are not using a mechanical lift and the router weight is fully supported by a shelf or another router, unscrew and remove the mounting screws from the rack. Three people can then lift the router and move it to the shipping crate.
   • If you are not using a mechanical lift and the router weight is not fully supported by a shelf or another router, three people should grasp the router while a fourth person unscrews and removes the mounting screws from the rack. The three lifters can then move the router to the shipping crate.
9. Place the router in the shipping crate or onto the pallet. If on a pallet, bolt the router to the pallet.
10. Cover the router with an ESD bag and place the packing foam on top of and around the router.
11. Replace the accessory box on top of the packing foam.
12. Securely tape the box closed or place the crate cover over the router.
13. Write the RMA number on the exterior of the box to ensure proper tracking.
