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.

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 387-23812-3300A0 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.

3. Backplane Each drive tray includes separate LED indicators for drive activity and drive status. Light pipes integrated into the drive tray direct light emitted from LEDs mounted next to each drive connector on the backplane to the drive tray faceplate, making them visible from the front of the system Figure 64 Drive tray LED identification Table 7 Drive power LED/activity LED behavior LED ICON LED Color Behavior Condition A,C Power LED N/A Stay off Fault Blue Solid on Present B,D Activity LED Green Solid on Access Red Solid on Failure 1Hz blink Rebuild 4Hz blink Locate NOTE: The drive activity LED is driven by signals coming from the drive itself. Drive vendors may choose to operate the activity LED different from what is described in the table above. Should the activity LED on a given drive type behave differently than what is described, customers should take the drive vendor specifications as a reference for the specific drive model to determine what the expected drive activity LED operation should be. / Backplane 43

3-5 2 x 2.5 Drive Bay Accessory Kit Chenbro Accessory Kit Product Code: 83H553237-006 for SATA/SAS module and 383-23780-3028A0 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.

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
