Cisco Catalyst 9300L-48P-4G-E — 48-Port PoE+ Switch with 4x1G Uplinks, Network Essentials

The Intelligent Edge Switch That Powers Your Entire Network — Without Compromise

When your business depends on seamless connectivity, every port matters. The Cisco Catalyst 9300L-48P-4G-E is not just a switch — it is the backbone of a future-ready network. Engineered for enterprises, SMBs, campus environments, and demanding IT deployments, this switch delivers enterprise-grade performance, robust Power over Ethernet Plus (PoE+) capability, and Cisco’s industry-leading Network Essentials software — all in a compact, stackable form factor.

Whether you are deploying IP phones, wireless access points, security cameras, or smart building IoT devices, the C9300L-48P-4G-E gives you the power, intelligence, and reliability your infrastructure demands.

What Is the Cisco C9300L-48P-4G-E? Key Specs at a Glance

The Cisco Catalyst 9300L is a fixed-configuration, Layer 3 managed switch purpose-built for access-layer and distribution-layer deployments. Here is what makes it stand out:

• 48 x PoE+ Downlink Ports — IEEE 802.3at compliant, supporting up to 30W per port
• 4 x 1G SFP Uplink Ports — for flexible fiber or copper uplink connectivity
• Total PoE Power Budget: 505W — enough to simultaneously power dozens of PoE devices
• Network Essentials License — Cisco IOS-XE with enterprise-class features included out of the box
• Stacking Capable — stack up to 8 switches for unified management
• ASIC-based Forwarding — non-blocking architecture for wire-speed performance
• Cisco DNA Center Ready — supports intent-based networking and automation

Why Choose PoE+ Over Standard PoE? Power That Goes the Distance

Eliminate the Clutter. Eliminate the Cost.

Traditional network deployments require separate power cabling for every device — access points, VoIP phones, PTZ cameras, digital signage, and more. The C9300L-48P-4G-E changes everything. With 48 PoE+ ports delivering up to 30W each and a combined PoE budget of 505W, you can power your entire edge ecosystem through a single Ethernet cable per device.

• No separate power adapters or outlets needed per device
• Lower installation costs — reduce electrician fees and cable management
• Centralized power management — monitor, schedule, and control device power from one console
• Uninterrupted uptime — pair with a UPS to keep all PoE devices online during outages

This is the switch that IT managers wish they had deployed years ago.

Cisco Network Essentials — Enterprise Features, Right Out of the Box

More Than Just Layer 2 Switching

The Network Essentials license included with this model is not a stripped-down starter package — it is a fully featured software suite that empowers your network from day one:

• Advanced QoS (Quality of Service) — prioritize voice and video traffic for crystal-clear calls
• MACsec Encryption — hardware-level, line-rate security on every port
• VLAN & Trunking Support — segment your network for security and performance
• IGMP Snooping — optimize multicast traffic for surveillance or media streams
• SGT (Security Group Tagging) — enforce zero-trust access policies at the edge
• IPv4 & IPv6 Routing — full dual-stack Layer 3 support for modern networks
• NetFlow Telemetry — real-time traffic visibility for troubleshooting and compliance

Upgrading to Network Advantage unlocks even more — including SD-Access, advanced automation, and EVPN VXLAN support.

Built for Campus, Branch, and Enterprise Access Layers

Where Does the Cisco 9300L-48P-4G-E Fit Best?

This switch was designed to excel in environments where density, reliability, and PoE power are non-negotiable:

• Corporate Office Networks — power entire floors of IP phones and laptops
• Education Campuses — support classroom tablets, APs, and smart boards simultaneously
• Healthcare Facilities — connect medical IoT devices and nurse call systems reliably
• Retail & Hospitality — drive guest Wi-Fi, POS terminals, and IP surveillance from one switch
• Warehouses & Manufacturing — ruggedized connectivity for industrial IoT and barcode scanners
• Data Center Edge / Branch Offices — consistent, manageable access infrastructure

Stackable Architecture — Scale Without Complexity

One Pane of Glass for Dozens of Switches

The Cisco Catalyst 9300L supports StackWise-160 technology, allowing you to stack up to 8 switches and manage them as a single logical unit. This delivers:

• Up to 160 Gbps of stack bandwidth — eliminating bottlenecks between switches
• Single IP address management — simplify your network topology dramatically
• Hitless failover — if one stack member fails, traffic seamlessly reroutes
• Flexible scalability — add switches to the stack without downtime or reconfiguration

For growing organizations, this is not just convenient — it is transformative.

Security Built Into the Silicon — Not Bolted On

Cisco Trustworthy Systems: Hardware-Level Protection

Cisco’s Trust Anchor technology embedded in the C9300L ensures:

• Secure Boot — verifies software integrity at every startup
• Image Signing — only Cisco-authenticated IOS-XE images run on the device
• Runtime Defenses — detect and respond to anomalous behavior in real time
• TAm (Tamper Detection) — physical security monitoring at the chip level

In an era where network devices are increasingly targeted by supply chain attacks and firmware exploits, the C9300L-48P-4G-E is the switch that fights back — before you even log in.

Cisco DNA Center Integration — The Future of Intent-Based Networking

• Troubleshoot faster with end-to-end path trace and client 360 visibility

Stop firefighting network issues. Start proactively managing your infrastructure.

Frequently Asked Questions About the Cisco C9300L-48P-4G-E

Q: What is the difference between C9300L and C9300? The C9300L is a lower-cost, fixed-uplink variant of the Catalyst 9300 series. It does not support modular uplink modules but offers the same ASIC performance and software stack at a more accessible price point — ideal for cost-conscious deployments that do not require uplink flexibility.

Q: Does this switch support stacking? Yes. The C9300L-48P-4G-E supports StackWise-160, allowing stacking of up to 8 units with a combined 160 Gbps bandwidth.

Q: What PoE standard does it support? It supports IEEE 802.3at (PoE+) on all 48 downlink ports with a total PoE budget of 505W.

Q: Is a license included? Yes. The “-E” suffix denotes the Network Essentials license is pre-included, giving you full Layer 3 feature access without additional software costs.

Q: Can it be managed through the cloud? Yes. The C9300L supports Cisco DNA Center and Meraki Dashboard (with appropriate licensing), enabling cloud or on-premise management.
