Solution
GPU cluster fabrics, leaf-spine links and high-density 400G/800G optical paths.
Review This TopologySwitch and NIC models, cage cooling form, lane mode, port map, rack route and fiber count.
Thermal headroom, FEC mode, MPO polarity and the difference between 800G links and two 400G branches.
Per-port link-up, DOM/DDM, FEC counters, thermal soak and labeled fiber-route records.
Plan the leaf-spine link from the switch cage and GPU fabric lane map, then verify cooling form, fiber count and breakout behavior before selecting optics.
