Cisco Catalyst C9300-24T-A — 24× 1G (no PoE) with modular 1/10/40G uplinks (Network Advantage)

What it is: A stackable, enterprise Layer-3 Catalyst 9300 with 24 × 10/100/1000 RJ-45 data ports (no PoE) and a modular uplink bay (swap in 1G, 10G, or 40G). Runs IOS-XE and ships with the Network Advantage (-A) feature set. Field-replaceable dual PSUs and hot-swap fans for serviceable closets.

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

• High-performance access without PoE costs: perfect for desktops, printers, thin clients, and servers.

• Uplink freedom: pick 4×1G, 4×10G, 8×10G, or 2×40G now—change later as you scale.

• Serious stacking: StackWise-480 delivers big stack bandwidth and single-IP operations.

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

• Service live: hot-swap PSUs/fans plus Perpetual/Fast PoE support for mixed stacks (even though this model itself is non-PoE).

MPLS availability depends on image/version.
