    Plug and play in our C9400 chassis. Performance is stable and reliable, zero downtime since install.

Questions & Answers

  • What are the first checks if the 48HN ports refuse power negotiation?

    Verify the chassis has sufficient PoE budget, check cabling quality (Cat5e or better), and use 'show power inline' to view port errors.

  • Which mounting clips come with the 48HN module?

    The accessory kit includes mounting ears, screws, dust caps, and cable management brackets.

  • How does the 48HN 5G multigig card differ from the 48H UPOE+?

    The 48HN supports up to 5G speeds with 90W UPOE+, while the 48H targets slightly lower speeds and different power profiles.

  • Is there a fiber-optic alternative to the 48HN multigig card?

    Yes, the C9400-LC-24XS or 48XS offer SFP+ and QSFP+ fiber interfaces for high-speed uplinks.

  • Which campus-edge deployments benefit most from 48HN?

    Ideal for education, healthcare, or enterprise edge switches needing high PoE power and moderate multigig speeds.

  • Which LEDs show 48HN emergency shutdown states?

    Amber or red port LEDs indicate shutdown from power or temperature errors; check 'show logging' for the root cause.

  • How to hot-swap a 48HN card without dropping PoE devices?

    Ensure redundant supervisor, pull the module gently, insert replacement, and confirm port and power status via CLI.

  • Which copper cable specs work reliably for 5G on the 48HN?

    Use Cat5e for up to 2.5G, Cat6 or Cat6A for 5G operation.

  • How can I confirm 90 W per-port on the 48HN?

    Connect a 90W device and use 'show power inline' to confirm full allocation and negotiation.

  • Can I mix 48HN ports with other PoE cards in the same chassis?

    Yes, mixed PoE and multigig cards are supported as long as total power budget is managed.

  • Which spare parts are included with the 48HN?

    Dust covers, mounting screws, cable managers, and a quick guide.

  • How do I reset per-port PoE priority on the 48HN?

    Use 'power inline priority' CLI command to adjust per-port power allocation.

  • What daily checks ensure stable 48HN operation?

    Monitor power draw, clear vents, check logs for errors, and periodically reboot if needed.

  • Does the 48HN support reach-extend for long runs?

    Yes, with the correct cable quality and supported PDs, extended Ethernet can be achieved.

  • Which CLI commands show 48HN temperature?

    'show environment' and 'show platform' display real-time temperature metrics.
