How to use
Install the DAC cable by inserting each QSFP28 connector firmly into the corresponding QSFP28 port until the latch engages. Ensure both network devices are powered down or support hot-plugging according to their documentation before connecting. After physical installation, verify link status through the devices’ management interfaces and configure interfaces for 100G operation if required. For optimal signal integrity, avoid tight bends and maintain recommended bend radius for the cable.
Usage recommendations
Use this DAC cable for short-distance, high-throughput connections within racks or between adjacent racks. Confirm compatibility with your switches and servers’ QSFP28 ports and, when possible, check vendor documentation for any required firmware or compatibility lists. Route the cable to minimize stress on connectors and avoid sources of excessive heat or mechanical strain.
