Questions & Answers

  • What are the first steps if the 48U card’s PoE isn’t delivering power?

    Check the power supply capacity, verify PoE is enabled for the port, inspect cabling, and use 'show power inline' to see error details.

  • Which RJ-45 dust covers ship with the 48U module?

    The kit contains dust covers for all ports, cable ties, and mounting hardware.

  • How does the 48U UPOE card differ from the non-PoE 48T?

    The 48U provides Universal PoE (up to 60W/port), while the 48T is data-only with no power delivery.

  • Are there metal-chassis alternatives to the 48U line card?

    Only Cisco Catalyst 9400 line cards are compatible with the chassis; no direct third-party alternatives.

  • In which floor-switch scenarios is the 48U typically deployed?

    It’s popular in high-density office or campus floors where many phones, APs, or IoT devices need UPOE.

  • Which LEDs show per-port power status on the 48U?

    Green is normal, amber indicates power negotiation failure or denied power; off means disabled port.

  • How do I hot-swap a 48U line card in a live rack?

    With redundant supervisors, unscrew the card, pull it out, insert a replacement, and verify with 'show module'.

  • What cable lengths guarantee full UPOE on the 48U?

    For full 60W UPOE, use Cat5e/Cat6 cabling up to 100 meters (328 ft).

  • Which PDs are incompatible with Cisco UPOE on the 48U?

    Most standards-based PDs are compatible, but always verify device specs—some legacy equipment may not negotiate properly.

  • How can I downgrade before removing the 48U card?

    Back up config, install supported IOS XE, set boot variable, and reload the chassis.

  • Which small parts bag ships with the 48U only?

    Dust caps, mounting screws, and cable managers are standard.

  • How do I clear PoE allocation on the 48U?

    Use 'clear power inline' or reset the interface to clear and re-allocate PoE.

  • What scheduled tasks keep the 48U running cool?

    Inspect and clean fans/vents, avoid over-populating high-power devices, and monitor temp via CLI.

  • Does the 48U support per-port power sensing?

    Yes, real-time per-port power usage and negotiation are supported.

  • Which CLI “show power” commands report 48U usage?

    'show power inline' and 'show environment power' display port and system-level usage.
