C9300-24S-A Description
The C9300-24S-A is a Cisco Catalyst 9300 Series stackable access switch built around 24 fixed 1G SFP fiber ports and a modular uplink bay, ordered with the Network Advantage license tier. Its fiber-only downlink layout targets access or aggregation closets where runs exceed structured copper distance limits or where existing cabling is already single-mode or multimode fiber, rather than the copper wiring closets that Catalyst 9300 RJ-45 SKUs serve. The switch ships with a 715W AC power supply (PWR-C1-715WAC-P) and carries no PoE capability, since SFP ports do not source PoE power. It joins other Catalyst 9300 (non-X) modular-uplink switches in an 8-member StackWise-480 stack at 480 Gbps per stack, and it accepts optional field-replaceable network modules such as the C9300-NM-8X (8x 10G/1G SFP+) for uplink speed migration. The Network Advantage tier on this SKU unlocks advanced routing protocols (BGP, EIGRP, IS-IS), network segmentation (VRF, VXLAN, TrustSec), automation interfaces (NETCONF, RESTCONF, YANG), and MACsec-256 encryption on top of the Layer 2 and basic routed-access feature set that ships on every C9300-24S variant. Because this SKU's minimum software baseline is Cisco IOS XE 16.11.1a, higher than the general Catalyst 9300 family floor of 16.5.1a, existing fleets standardizing on an older release train need a software plan before adding this fiber model to a stack.

Product Performance
Key Features
All 24 downlink ports are 1G SFP, so the switch plugs directly into existing single-mode or multimode fiber runs without media converters, which matters for closets where copper distance or EMI exposure ruled out RJ-45 access switches.
The uplink bay accepts network modules such as the C9300-NM-8X, so a stack can move from 1G/10G uplinks to 25G or 40G later by swapping the module instead of replacing the chassis.
This SKU’s Network Advantage tier adds BGP, EIGRP, IS-IS, VRF, VXLAN, and Cisco TrustSec on top of Layer 2 switching, which matters for stacks that need to originate routing adjacencies or carry segmentation policy rather than only forward Layer 2 traffic to a distribution switch.
Up to 8 units combine into a single logical switch over StackWise-480 at 480 Gbps, letting a wiring closet grow port density without adding separate management points or spanning-tree domains.
Because MACsec-256 and model-driven telemetry (NETCONF/RESTCONF/YANG) ship with Network Advantage, this fiber SKU can carry encrypted links and programmatic monitoring in segments where a fiber run crosses less trusted physical space, such as between buildings.
StackPower lets up to 4 stacked C9300-24S-A members share power across a ring, extendable to 8 members with the XPS-2200 external supply, so a unit that loses its own power supply can keep drawing power from the ring instead of dropping its fiber uplinks until a replacement is installed.
Application Scenarios
Deployed where an access or aggregation switch must terminate fiber runs between buildings or floors that exceed the 100m copper limit, collecting single-mode or multimode fiber drops into a stackable switching layer.
Used in campus segments where Network Advantage’s MACsec-256 and VRF-based segmentation are required to carry encrypted or policy-segmented traffic across a fiber-connected wiring closet, such as a link to a less physically secured building.
Placed as a stack member in an SD-Access or NETCONF/RESTCONF-managed fabric where Network Advantage’s automation feature set is used to provision and monitor the switch centrally rather than through box-by-box CLI configuration.

C9300-DNA/DNX-A-24 |
- The C9300-24S-A and C9300-48S-A share the same fiber-only SFP downlink design and identical PWR-C1-715WAC-P default supply, but the C9300-48S-A doubles port count and switching capacity to 256 Gbps; a design that only needs 24 fiber drops does not gain anything from the larger chassis and pays for uplink and rack space it will not use, so port count should be sized to the actual fiber drop count before comparing license tier.
- Against the C9300-24T-A, the C9300-24S-A trades a smaller default power supply requirement upward: the fiber SKU needs the 715W supply while the copper C9300-24T-A ships on a 350W supply, because the fiber transceivers and SFP cage electronics draw more baseline power than fixed RJ-45 PHYs even with PoE excluded from both. A design with copper-reachable endpoints and no distance or EMI driver for fiber can standardize on the C9300-24T-A for a lighter power footprint.
- The C9300-24S-A also carries a higher minimum software floor (Cisco IOS XE 16.11.1a) than the C9300-24T-A (16.5.1a); a fleet standardized on an older Catalyst 9300 image train needs to confirm the running release supports the fiber SKU, or plan an upgrade, before mixing C9300-24S-A units into an existing stack.
- Ordering priority across this group should start with port medium (fiber vs. copper) and port count, since both are physically fixed at purchase, and treat license tier as a separate later decision that does not change which base hardware SKU to order.
Selection Guide
1. Fiber Medium Requirement Over Copper
Choose the C9300-24S-A only when the deployment needs 1G SFP fiber ports; the identical Network Advantage feature set is also available on the C9300-24T-A with RJ-45 copper ports at a lower default power supply rating, so a design without a distance, EMI, or existing-fiber-plant driver gains nothing from the fiber SKU and takes on the higher 715W power floor for no functional benefit.
2. Port Count Against the C9300-48S-A
A stack needing more than 24 fiber drops per unit should move to the C9300-48S-A instead of adding a second C9300-24S-A member purely for port count, since consolidating into fewer, higher-density units reduces the number of stack members and uplink modules to manage; a design under 24 fiber ports per wiring closet has no reason to size up.
3. Advantage-Only Capabilities Set The Downgrade Boundary
BGP/EIGRP/IS-IS routing, VRF/VXLAN segmentation, MACsec-256, and NETCONF/RESTCONF automation are the capabilities this SKU’s Network Advantage tier adds over Essentials; a pure Layer 2 fiber access role with no dependency on any of them can move to the C9300-24S-E at Network Essentials and skip the Advantage software subscription cost entirely.
4. Software Baseline Before Mixed-Model Stacking
The C9300-24S-A needs Cisco IOS XE 16.11.1a or later; a stack running on an older Catalyst 9300 baseline requires an upgrade window before this fiber SKU can join, so the software floor rather than hardware compatibility sets the timeline.
Ordering Checklist
|
Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Smart Account binding |
Confirm the target Smart Account and Virtual Account before ordering. |
Network Advantage entitlement and the matching software subscription are tied to Smart Licensing; ordering to the wrong account can stall activation. |
|
Subscription tier match |
Confirm the Cisco Catalyst or Cisco DNA subscription ordered is Advantage tier, matching the Network Advantage hardware license. |
A DNA Essentials subscription paired with Network Advantage hardware is only valid at renewal, not on a new order. |
|
Minimum software release |
Confirm the target IOS XE release is 16.11.1a or later before staging the switch. |
The C9300-24S-A has a higher software floor than most Catalyst 9300 copper SKUs; an older image will not support this fiber SKU. |
|
Uplink network module |
Confirm whether a network module (e.g., C9300-NM-8X) is needed and ordered separately, or that C9300-NM-BLANK is specified if no module is installed. |
The uplink bay ships empty; an uncovered bay without a module or blank leaves the airflow path open and is not shippable as configured. |
|
SFP optics compatibility |
Confirm the 1G SFP optics or cables to be installed are on the Cisco optics compatibility list for Catalyst 9300. |
An unsupported SFP can be rejected by the switch even if the physical form factor matches. |
