How to use
Ensure both endpoints have compatible QSFP28 ports and that devices are powered down or support hot-plugging per vendor guidance. Insert each QSFP28 connector into the corresponding port until it seats firmly and the latch (if present) engages. Verify the link status on connected devices and configure port settings as required by your network or storage equipment. For best signal performance, avoid tight bends and keep the cable clear of sources of electromagnetic interference.
Usage recommendations
Use this QSFP28 DAC cable for direct short-distance connections inside racks and between adjacent racks. Confirm firmware and port compatibility on switches, NICs and HBAs for InfiniBand or 100GbE operation. Store the cable coiled loosely and avoid sharp bends to preserve cable integrity and performance.
