Guidelines for Packing Hardware Components for Shipment
To pack and ship individual components:
When you return components, make sure they are adequately protected with packing materials and packed so that the pieces are prevented from moving around inside the carton.
Use the original shipping materials if they are available.
Place individual components in antistatic bags.
Write the RMA number on the exterior of the box to ensure proper tracking.
Do not stack any of the hardware components.
Packing the ACX Series Router for Shipment
To pack the router for shipment:
- Retrieve the shipping box 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.
- On the console or other management device connected to
the Routing Engine, enter CLI operational mode and issue the following
command to shut down the router software.
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 CLI Explorer.
- Attach an ESD grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
- Shut down power to the router by pressing the AC input
switch or DC circuit breaker for all power supplies to the off (
O
) position. - Disconnect power from the router.
- Remove the cables that connect to all external devices.
- Remove all field replaceable units (FRUs) from the router.
