1-8 System Packaging
The original Chenbro packaging, where the server system is delivered, is designed to provide protection to a fully configured system
and tested to meet ISTA (International Safe Transit Association) Test Procedure 1A. The packaging is also designed to be re-used for
shipment after system integration has been completed.
The original packaging includes –the shipping box, and various protective inner packaging components, which are designed to
function together as a protective packaging system. When reused, all of the original packaging material must be used, including box
and each inner packaging component. In addition, all inner packaging components MUST be re-installed in the proper location to
ensure adequate protection of the system for subsequent shipment.

NOTE: The design of the inner packaging components does not prevent improper placement within the packaging assembly.
There is only one correct packaging assembly that will allow the package to meet the ISTA (International Safe Transit Association)
Test Procedure 1A (2008). Failure to follow the specified packaging assembly instructions may result in damage to the system
during shipment.
