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 choose to do so, Chenbro advises you 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. More than one person to operate with mechanical assist
tools 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 L3 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 system integration has been completed.
The original packaging includes the shipping box and various protective inner packaging components, which are designed to as a
protective packaging system. When reused, all the original packaging materialsmust be included such as boxes 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.
