Cisco Catalyst C9300-48T-A — 48× 1G (no PoE) access with modular 1/10/25/40G uplinks (Network Advantage)

What it is: A stackable, enterprise Layer-3 Catalyst 9300 with 48 × 10/100/1000 RJ-45 data ports (no PoE) and a modular uplink bay so you can choose uplink speed now and swap later. Runs IOS-XE and ships with the Network Advantage (-A) feature set for advanced routing/segmentation. Dual hot-swap PSUs and field-replaceable fans make it closet-ready and service-friendly.

Why buyers pick C9300-48T-A (plain English)

• High-density access without PoE cost: ideal for desktops, printers, thin clients, and server/edge wiring.

• Uplink flexibility: pick modules for 1G / 10G / 25G / 40G depending on your distribution/core—upgrade later without replacing the chassis.

• Stacks like a beast: StackWise-480 lets up to 8 switches behave like one, with fast failover.

• Advanced campus features included: Network Advantage adds richer L3 (BGP/OSPF/EIGRP, PBR, VRF-lite, etc.) and SD-Access readiness.

• Built for uptime: hot-swap PSUs/fans and ISSU-style maintenance options in typical designs keep outages rare.

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

Form factor

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

What to order with it (common adds)

• Uplink module that matches your core (4G / 4X / 8X / 2Q, etc.)

• SFP/SFP+/QSFP optics or DAC/AOC cables for uplinks/stacking

• Second PSU for 1+1 redundancy

• 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 where endpoints don’t need PoE but you still want stacking + modular uplinks + advanced routing.

• Choose C9300-48P if you need PoE+.

• Choose C9200/C9200L if fixed uplinks and simpler power are OK at a lower price.

• Choose mGig C9300 models (24UX/48UXM) if you need 2.5/5/10G downlinks for high-speed APs.

TL;DR

C9300-48T-A is the enterprise non-PoE access workhorse: 48× 1G data ports, modular uplinks up to 40G, StackWise-480, hot-swap PSUs/fans, and Network Advantage features—built for fast, flexible, high-availability campus access without paying for PoE you don’t need.
