Cisco Catalyst C9300-24P-A — 24× 1G PoE+ access with modular 1/10/40G uplinks (Network Advantage)

What it is: A stackable, enterprise Layer-3 Catalyst 9300 switch with 24 × 10/100/1000 RJ-45 PoE+ ports and a modular uplink bay (swap in 1G, 10G, or 40G options). Ships with IOS-XE and the Network Advantage (-A) license for advanced routing/segmentation. Field-replaceable dual PSUs and hot-swap fans keep closets serviceable.

Why buyers pick C9300-24P-A (plain English)

• Real PoE at the edge: 24 ports of 802.3at PoE+ (up to 30W/port)—perfect for APs, phones, and cameras.

• Uplink freedom: choose the network module you need today (1G or 10G or 40G) and swap later as you scale.

• Stacks like a champ: StackWise-480 delivers high-bandwidth stacking and single-IP operations across up to 8 members.

• Advanced features included: Network Advantage enables richer L3 (BGP/OSPF/EIGRP, PBR, VRF-lite, MPLS*), segmentation, and SD-Access readiness.

• Service without outages: hot-swap PSUs/fans, Perpetual/Fast PoE, and ISSU options in typical designs.

MPLS availability depends on image/version; many deployments use Advantage for campus/MPLS edge.

Access ports

• 24 × 10/100/1000 RJ-45, PoE+ 802.3at (up to 30W/port)

Uplinks (modular bay; order one)

• C9300-NM-4G (4 × 1G SFP)

• C9300-NM-4X (4 × 10G SFP+)

• C9300-NM-2Q (2 × 40G QSFP)

• C9300-NM-8X (8 × 10G SFP+)

Power / PoE

• Two PSU bays (field-replaceable) for capacity and 1+1 redundancy

• System PoE budget depends on PSU choice; select wattage to match your endpoint plan (add ~20–30% headroom)

• Perpetual & Fast PoE keep endpoints powered through reloads/boot

Stacking / HA

• StackWise-480 (up to 480 Gbps stack bandwidth)

• Up to 8 members; role redundancy and hitless failover behaviors in typical designs

Software / features (Network Advantage)

• IOS-XE, full enterprise L3 (OSPF/EIGRP/BGP, PBR, VRF-lite; MPLS/SRv6 where supported)

• Segmentation & security: TrustSec hooks, SGTs, 802.1X/MAB, MACsec* (model/optics dependent), DHCP snooping, DAI

• Ops/telemetry: NetFlow/Flexible NetFlow, model-driven telemetry, WebUI/CLI, DNA Center readiness

Hardware serviceability

• Hot-swap fans (FRUs)

• Hot-swap PSUs (AC/DC options by region)

Form factor

• 1U rack-mount, wiring-closet friendly acoustics

What to order with it (common adds)

• Uplink module: pick 4G/4X/2Q/8X to match your core/aggregation

• SFP/SFP+/QSFP optics or DAC/AOC for the uplinks

• Second PSU for redundancy and/or higher PoE budget

• DNA subscriptions if you’re rolling out SD-Access or centralized automation

Where it fits (and when to choose something else)

• Perfect for: campus/branch access with powered endpoints and a need to pick your uplink speed (1G/10G/40G).

• Step up to C9300 mGig (e.g., 24UX/48UXM) if you need 2.5/5/10G downlinks for Wi-Fi 6/6E APs.

• Step down to C9200/C9200L if fixed uplinks and simpler power are fine at a lower price point.

TL;DR

C9300-24P-A = 24× PoE+ access, modular 1/10/40G uplinks, StackWise-480, dual hot-swap PSUs & fans, and Network Advantage features—built for modern access layers that want power, resilience, and growth headroom.
