17 1-7 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.

19 1-9 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 to the system for subsequent shipment. Table 5 System packaging information Part Number Single/ Bulk Form factor (mm) Support level A0 Single 830 x 590 x 190 L5 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.

54 3-5 2 x 2.5 Drive Bay Accessory Kit Chenbro Accessory Kit Product Code: 83H for SATA/SAS module and A0 for NVMe module. The 2U product family provides the option to support 2 x 6 Gbps SATA SSDs or 2 x PCIe NVMe SSDs installed to a drive module mounted in the back of the system. Figure '' 2-bay drive module Table 18 Solution and operating condition for bay drive module Drive type Application Drive thickness Drive quantity Air duct System ambient temperature SATA SSD OS/Cache 7mm 2 X mm 2 X 35 3 NVMe SSD Cache 7mm 2 V mm 1 V 35 4 System fan required NOTE : 1. 2-port drive module is designed for OS and cache applications in which 7mm/9.5mm SATA SSD or 7mm/15mm NVMe are suggested. 2. For these configurations, stressed program is set as 100% random write which generates the most heat as the worst scenario. Solutions above are suggested for better thermal performance under this stressed condition. 3. Disk/flash drive behavior in OS/cache application is similar to mix random read/write which may allow users to adopt 2x 15mm NVMe. Physical test is suggested to evaluate the operating condition. The backplane includes several connectors and a jumper block, as defined in the following illustrations. / Backplane 54
