1-6 Available Rack Mounting Kit Options (Refer to “ Installation”)
Advisory Note – Available rack and cabinet mounting kits are not designed to support shipment of the server system while installed
in a rack. If you chose to do so, Chenbro advises you to verify your shipping configuration with appropriate shock and vibration
testing, before shipment. Chenbro does not perform shipping tests which cover the complex combination of unique rack offerings
and custom packaging options.
Caution: Exceeding the specified maximum weight limit of a given rail kit or misalignment of the server in the rack may result in
failure of the rack rails, causing damage to the system or personal injury. Two persons to operate or the use of a mechanical assist
tool to install and align the server into the rack is highly recommended.
Available rack mounting kits:

1-8 System Packaging
The original Chenbro packaging, where the server system is delivered, is designed to provide protection for L5 configuration and
tested to meet ISTA (International Safe Transit Association) Test Procedure 1A (2008). The packaging is also designed to be reused
for shipment after the 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 reinstalled in the proper location to
ensure adequate protection of the system for subsequent shipment.
Table 5 Syst em packaging information
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.
Table 6 Product weight information
NOTE: A L5 system does not include M/B, processors, memory, drives, or add-in cards. It is the system configuration as
shipped from Chenbro. Weights of integrated system (system configurations that include the items above) will vary
depending on the final system configuration. For the 1U product, a fully integrated un-packaged system can weigh up to 40
Lbs. (18+ Kg).
