    If your query’s “hot” refers to ambient temperature, follow these guidelines:

    | Temperature Range | Action Required | |------------------|------------------| | 25–30°C (77–86°F) | Standard operation, ensure front-to-back airflow unobstructed. | | 30–35°C (86–95°F) | Reduce adjacent equipment density. Check fan speed via CLI: show system environment | | >35°C (>95°F) | Do not install – The 3B will throttle performance and may shut down. |

  • If the fans stay at 100% for >2 minutes, you have a "hot" thermal misconfiguration. Power down and check: Call Knox Tech Support (USA): +1 800-552-5669 –
