Questions & Answers

  • What initial diagnostics help if the 24S SFP links are all down?

    Check SFP modules are installed properly, use 'show interface' to ensure ports are enabled, and inspect cabling for physical damage.

  • Which SFP dust caps are bundled with the 24S card?

    Accessory kit contains dust caps for each port, mounting brackets, and screws.

  • How does the 24S 1 G fiber module differ from the 24-port RJ45?

    The 24S offers SFP slots for fiber modules, while RJ45 cards (like 24T) support copper cabling.

  • Is there a gigabit copper card alternative to the 24S?

    Yes, use the C9400-LC-24T for 24-port RJ45 gigabit copper connectivity.

  • Which small-branch designs fit the 24S wall-mount?

    24S is suited for small branch offices or sites needing secure fiber uplinks and compact form factor.

  • Which front-panel LEDs indicate fiber port alarms on the 24S?

    Amber or off means fault or no link; green is healthy connection.

  • How do I hot-swap a 24S without rebooting the chassis?

    With OIR, pull the card, insert the new, and check recognition in 'show module'.

  • Which SFP models (SX/LX) are validated on the 24S?

    Cisco SFP SX (short range), LX (long range), and some third-party modules are compatible.

  • How can I loopback test each 24S port?

    Insert loopback plugs and use 'test cable-diagnostics tdr' or 'show interface' for results.

  • Can I replace a 24S with a 24-port copper card in-place?

    Yes, as long as the chassis and software support both cards.

  • Which accessory kit ships with the 24S only?

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

  • How do I clear 24S MAC-address tables?

    'clear mac address-table dynamic' in EXEC mode.

  • What periodic cleaning prevents dust in the 24S cage?

    Use fiber-safe compressed air and keep unused ports capped.

  • Does the 24S support BiDi SFP modules?

    Yes, bidirectional SFPs are supported with compatible firmware.

  • Which CLI commands display 24S port errors?

    'show interfaces counters errors' gives detailed stats.
