Questions & Answers

  • What should I check if the UX module’s mGig ports aren’t negotiating?

    Verify cabling (Cat5e/Cat6/Cat6A), check both switch and end device port settings, and use 'show interface' to see negotiation status.

  • Which fiber/copper adapters come with the 48UX?

    The kit typically includes dust covers, mounting hardware, and may include test patch cables for copper/fiber ports.

  • How is the 48UX mGig card different from the 48U copper only?

    The 48UX supports 100M/1G/2.5G/5G/10G multigig speeds per port, while the 48U is 1G only.

  • What standard single-vendor alternatives exist for the 48UX?

    Other Catalyst line cards offer similar density, but 48UX is unique for its full mGig and PoE+ support.

  • What smart-building use cases leverage the 48UX card?

    The 48UX excels in modern smart buildings requiring high-density multigig, Wi-Fi 6/6E APs, and IoT device connectivity.

  • Which status LEDs help identify 48UX PoE issues?

    Amber or off port LEDs mean PoE negotiation has failed or power is denied; check system log for specific causes.

  • How do I hot-swap a 48UX line card without downtime?

    With redundant supervisor and OIR support, remove the card, insert the new one, and confirm via 'show module'.

  • Which cable types (Cat5e/Cat6) work best with the 48UX?

    Cat6A or higher is best for 10G; Cat5e/Cat6 for up to 2.5/5G operation.

  • How can I verify per-port power drawn on the 48UX?

    Use 'show power inline' to monitor each port’s PoE/PoE+ draw.

  • Can I downgrade IOS before removing the 48UX?

    Yes, but always ensure hardware compatibility and back up configuration before downgrading IOS.

  • Which faceplate clips ship with the 48UX card?

    Faceplate screws, cable management clips, and dust covers are typically included.

  • How do I flush VLANs on the 48UX module?

    Use 'no vlan [ID]' in config mode or 'clear vlan' for full table flush.

  • What cleaning procedures avoid dust buildup on the 48UX?

    Use compressed air, fiber-safe wipes, and keep unused ports covered with dust caps.

  • Does the 48UX support EnergyWise for power savings?

    Yes, EnergyWise is supported for granular per-port energy management.

  • Which “show mGig” commands monitor link speed on 48UX?

    Use 'show controllers ethernet-controller' and 'show interfaces capabilities' for current link negotiation.
