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 is Cisco C9404R used for?

    Cisco C9404R is a 4-slot Catalyst 9400 chassis for builds that need modular line-card selection in a smaller frame. It provides 2 line-card slots, 2 supervisor slots, and up to 96 front-panel ports with 48-port line cards.
  • Does C9404R come with supervisors or line cards?

    No. C9404R is the chassis SKU, so supervisors, line cards, power supplies, licenses, and optics must be specified separately unless a seller quotes a configured system.
  • How many line cards does C9404R support?

    C9404R supports 2 line cards in slots 1 and 4. This makes it the smallest Catalyst 9400 chassis option when modular hardware is needed but port density is limited.
  • Can C9404R use redundant supervisor engines?

    Yes. C9404R supports 1+1 supervisor redundancy in slots 2 and 3. High-availability designs should use matching supervisor models rather than mixing supervisor types.
  • How is C9404R different from C9407R?

    C9404R has 4 total slots, 2 line-card slots, and 4 power-supply bays. C9407R has 7 total slots, 5 line-card slots, and 8 power-supply bays for higher access density.
  • What power supplies does C9404R support?

    C9404R supports field-replaceable Catalyst 9400 AC or DC power supplies such as 2100W AC, 3200W AC, 3200W titanium AC, and 3200W DC models. Power design depends on line cards and PoE load.
  • Which fan tray is used with C9404R?

    C9404R uses the C9404-FAN tray. It is a single hot-swappable fan tray with 8 fans and can be serviced from the front or rear of the chassis.
  • When is C9404R not the right chassis?

    C9404R is not the right chassis when the design needs more than 2 line-card slots or more than 96 1G access ports. C9407R or C9410R should be evaluated for higher slot density.
