C9404R Description

C9404R
The Cisco Catalyst C9404R chassis delivers enterprise-grade, modular access switching in a 4-slot form factor. Built on the Catalyst 9000 family, the C9404R supports mission-critical security, IoT, mobility, and cloud services through up to 9 Tbps of fabric bandwidth, high-density IEEE 802.3bt PoE (60 W/90 W), redundant supervisors, and serviceable fan trays. Ideal for aggregation or access layers, it scales to 384 access ports (1–10 Gbps copper/fiber) and offers advanced resilience with dual supervisors (1+1), Cisco StackWise® Virtual, ISSU, NSF/SSO, and uplink redundancy.

Questions & Answers

  • What should I do if my C9404R chassis doesn’t recognize a new line card?

    Verify the card is fully seated, the chassis and card are compatible, and the correct IOS XE version is running. Check slot LEDs and console logs for hardware recognition errors.

  • Which spare parts are bundled with the C9404R model?

    Expect rack-mount ears, screws, grounding hardware, power cords, console cable, and often a cable management kit.

  • How many more ports does the C9404R have compared to a fixed switch?

    The C9404R supports up to four modular line cards, greatly exceeding fixed-switch models for port and uplink expansion.

  • Is there a compact alternative to the four-slot C9404R for small closets?

    Yes, Catalyst 9300 and some fixed 9400 series provide smaller footprints with many similar features.

  • What typical campus use cases fit the C9404R chassis?

    The C9404R is suitable for small campus cores, edge aggregation, or as a modular distribution switch in a multi-tier architecture.

  • How do I interpret the “status” LED patterns on the C9404R?

    Solid green means normal, amber indicates minor fault, red signals critical error. Refer to the hardware guide for detailed codes.

  • What’s the procedure to replace a failed fan tray in a running C9404R?

    Unscrew the tray, slide it out, insert the new fan tray firmly, and verify fan LEDs turn green. No power-down is needed.

  • Which DC power modules are supported on the 9404R?

    The 9404R accepts Cisco 2100W and 3200W DC power modules; check datasheet for exact part numbers.

  • What altitude ranges are valid for operating a C9404R?

    Up to 6,000 feet (1,800 m) at full specifications; derate maximum temperature above that altitude.

  • How do I roll back IOS XE on a C9404R after a bad update?

    Copy the previous stable image to flash, change the boot variable, and reload the chassis. Always backup configuration first.

  • Can other vendor devices emulate the C9404R in lab tests?

    While similar hardware exists, exact feature set and IOS XE behavior are unique to Cisco Catalyst 9400 series.

  • What faceplate tools are needed for installing the C9404R?

    Typically just a Phillips screwdriver and provided rack-mount screws are needed.

  • How can I erase the configuration on a Catalyst 9404 switch?

    Connect to console, enter 'write erase' in privileged EXEC mode, then reload the switch.

  • What daily health checks should be done on the 9404R?

    Monitor CPU/memory, check port status, verify power/fan health, and back up the current config.

  • Does the C9404R work with Cisco StackWise Virtual?

    Yes, C9404R supports StackWise Virtual for chassis stacking, if running compatible supervisor and IOS version.

  • What are the best commands to trace packet drops on the C9404R?

    Use 'show interface', 'show platform hardware qfp active', and 'show logging' for tracing errors and drops.
