Questions & Answers

  • What initial steps should I take if the 48XS module ports aren’t linking?

    Check for proper SFP+ module insertion, compatible fiber cables, and verify the module is seated. Review LEDs and use 'show interface' for errors.

  • Which cables and ejector clips are included with the 48XS card?

    You’ll receive SFP+ port dust covers, ejector levers, and sometimes short fiber patch cables for testing.

  • How does the 48-port fiber card differ from the 24XS model?

    The 48XS offers double the port density compared to 24XS, making it ideal for large-scale aggregation and backbone uplinks.

  • Is there a copper alternative that matches the 48XS in density?

    No, currently only multigig copper cards (like 48UX) approach that port count, but 48XS remains the primary high-density SFP+ card.

  • In which backbone designs is the 48XS fiber card typically used?

    The 48XS is deployed in campus or datacenter core/aggregation, supporting high-speed fiber connectivity and redundancy.

  • Which front-panel LEDs signal port errors on the 48XS?

    A solid or blinking amber LED signals a port or link fault; green means link is up and healthy.

  • How do I hot-swap a 48XS line card in a running chassis?

    If the chassis supports OIR, loosen the screws, pull out the card, insert a new 48XS, and let the chassis recognize it automatically.

  • What SFP/SFP+ transceivers are validated for the 48XS?

    Cisco official SFP/SFP+ transceivers (SR, LR, ER, ZX, etc.) are validated for best performance.

  • What fiber types (OM4/SMF) work with the 48XS ports?

    Both multi-mode (OM3/OM4) and single-mode (SMF) fibers are supported, depending on the SFP+ installed.

  • How do I load firmware patches onto the 48XS card?

    Firmware is updated via the main switch—copy the image to flash, update boot variable, and reload as needed.

  • Can I replace a 48XS with a 48S card in the same slot?

    Yes, as long as both are supported by your chassis and running compatible IOS XE versions.

  • Which accessory kit ships with the 48XS line card?

    Mounting screws, SFP+ port dust covers, and a quick install guide are included.

  • How do I clear MAC address entries on the 48XS?

    Use 'clear mac address-table dynamic interface [id]' in privileged EXEC mode.

  • What routine inspections prevent 48XS port degradation?

    Inspect for dust, clean connectors, review logs for errors, and check cable seating regularly.

  • Does the 48XS support MACsec on all ports?

    Yes, line-rate MACsec encryption is available with the right IOS XE and license.

  • Which CLI commands show 48XS traffic counters?

    'show interfaces counters' and 'show controllers' provide detailed port statistics.
