Questions & Answers

  • What initial steps should I take if the 48HX ports remain at 1G?

    Ensure connected devices support higher speeds, use Cat6A or better cabling, and check port settings for forced speed or duplex.

  • What up to 10G cabling connectors are included with the 48HX?

    Accessory kit provides dust covers, cable ties, and mounting hardware for all ports.

  • How is the 48HX multigig UPOE+ card different from the 48HN?

    The 48HX offers 10G/5G/2.5G/1G copper with UPOE+, while the 48HN is optimized for up to 5G speeds and high PoE budget.

  • Is there a cheaper multigig copper only card than the 48HX?

    Yes, the 48HN provides multigig functionality at a lower maximum speed and is more cost-effective for certain deployments.

  • Which high-density floor-switch designs suit the 48HX?

    Best for large campus, education, or healthcare sites where high-speed access and maximum PoE+ are needed.

  • Which LEDs show multigig link negotiation status on the 48HX?

    Solid green indicates healthy link at negotiated speed; amber or off means problem or no connection.

  • How to hot-swap a 48HX card mid-shift without service impact?

    If dual supervisors are present, pull the old card, insert the new, and verify via 'show module'.

  • Which cable categories (Cat6a/Cat7) are certified for 10G on 48HX?

    Cat6A for 10G, Cat7 for optimal EMI resistance; lower categories limit speed.

  • What steps verify UPOE+ at full 90 W on the 48HX?

    Use 'show power inline' and verify 'Power Allocated' column; test with a 90W PD to confirm full allocation.

  • Can I test the 48HX with third-party PoE-PD devices?

    Yes, most IEEE-compliant PoE-PD devices are compatible, but verify device specs for power class.

  • What accessory kit ships with the 48HX only?

    Dust caps, mounting hardware, cable managers, and quick start card.

  • How do I clear 48HX PoE event logs?

    Use 'clear logging' and check per-port logs with 'show power inline' for event history.

  • What preventive measures reduce 48HX fan-noise issues?

    Keep vents clear, avoid overloading PoE budget, and ensure proper rack airflow.

  • Does the 48HX support AES-256 MACsec on all ports?

    MACsec is supported on all ports with correct software and licensing.

  • Which CLI commands report 48HX port statistics?

    'show interfaces counters' and 'show power inline' provide traffic and power metrics.
