Key Architecture & System Highlights

The Cisco Catalyst C9300 Series is Cisco’s flagship stackable enterprise switching platform. Powered by custom Programmable Application-Specific Integrated Circuits (UADP ASIC), the C9300-48P ensures investment protection through open programmable features and hardware-level telemetry capability.

Unified Access Data Plane (UADP) Architecture

At the heart of the C9300-48P is the UADP 2.0 ASIC architecture. This flexible silicon engine allows hardware allocation of Layer 2 and Layer 3 forwarding tables, Access Control Lists (ACLs), and Quality of Service (QoS) entries. It provides consistent throughput regardless of packet size or active feature sets.

Cisco StackWise-480 Technology

StackWise-480 technology provides industry-leading stacking bandwidth of 480 Gbps. Up to 8 switches can be united into a single logical unit with unified management, single IP address management, and distributed control plane capabilities. For organizations requiring modular uplink flexibility or lower stack bandwidths, compare this with fixed-stacking solutions such as the Cisco C9200L-48PXG-4X Switch or the entry-level Cisco C9200L-48PXG-2Y Switch.

Cisco StackPower Technology

Cisco StackPower is an innovative power-sharing feature that aggregates power supplies across a stack, sharing energy across multiple switches for redundancy and efficiency. StackPower allows power pooling and intelligent power allocation across connected switches, minimizing power supply costs while ensuring zero-downtime operation for critical PoE endpoints.

Power over Ethernet (PoE+) Capabilities & Energy Management

The C9300-48P provides up to 30 Watts of power per port on all 48 ports simultaneously when equipped with redundant power supply units. This high-density PoE output is essential for modern business applications including Wi-Fi 6 Access Points, pan-tilt-zoom (PTZ) IP cameras, smart lighting, and enterprise VoIP phones.

If your organization requires comprehensive voice-over-IP deployments alongside your network switches, NexoGet supplies compatible desktop devices such as the Cisco C9300-24P Switch for smaller branches, as well as enterprise IP phones like the Cisco CP-8861-K9 IP Phone, Cisco CP-8845-K9 IP Phone, and Cisco CP-8865-K9 IP Phone.

Key PoE Features:

• Perpetual PoE: Maintains PoE power supply during a switch reboot, keeping IP cameras and IoT sensors running continuously without power interruption.
• Fast PoE: Restores power to endpoints in less than 5 seconds after power restoration, without waiting for the operating system to completely load.
• Energy Efficient Ethernet (EEE): Reduces energy consumption during low-traffic periods in compliance with IEEE 802.3az standards.

Modular Uplink Architecture & Network Modules

Unlike fixed-uplink switches, the Cisco C9300-48P supports hot-swappable uplink network modules, allowing network architects to adapt uplink bandwidth as requirements expand. Network operators can choose between 1G, 10G, 25G, or 40G modules.

For modular expansion across intermediate Catalyst lines, consider comparing uplink options such as the Cisco C9200-NM-4X Network Module, Cisco C9200-NM-2Y Network Module, or Cisco C9200-NM-2Q Network Module. If unused slots require protection, protect chassis airflow using the Cisco C9200 Blank Network Module.

Security, Automation, and SD-Access Integration

Security is natively embedded into the hardware of the Cisco Catalyst C9300-48P switch. Operating on Cisco IOS XE, the platform delivers automated network segmentation, advanced threat detection, and encrypted traffic visibility.

Software-Defined Access (SD-Access)

SD-Access is Cisco’s premier enterprise fabric automation architecture. The C9300-48P acts as an entry fabric edge node, enabling policy-based automation from the cloud to the campus edge. This simplifies user onboarding, enforcement of security policies, and automated segmentation across corporate users and guest networks.

Encrypted Traffic Analytics (ETA)

With hardware-level telemetry, the switch utilizes Encrypted Traffic Analytics (ETA) to identify malware threats within encrypted data streams without decrypting the payload, ensuring strict privacy compliance alongside maximum network protection.

Advanced Security Capabilities:

• AES-256 MACsec Encryption: Provides line-rate link-layer encryption between switches and host devices.
• Trust Anchor Technologies: Hardware-anchored Secure Boot and Secure Unique Device Identification (SUDI) prevent counterfeit hardware and unauthorized firmware execution.
• Cisco TrustSec: Enforces role-based Access Control Lists (SGT/SGACL) for dynamic network segmentation.

Choosing the Right Enterprise Switching Solution

When planning your enterprise infrastructure, understanding model differences across Cisco’s portfolio guarantees optimal ROI and network stability. If your application calls for compact footprint solutions or secondary branch sites, explore additional options in the NexoGet store:

Compact & Edge Alternatives

For smaller deployments or wiring closets with reduced PoE requirements, consider compact switches such as the Cisco C9200CX-8UXG-2X Switch, the fanless Cisco C9200CX-12P-2XGH Switch, or the versatile Cisco C9200CX-8P-2XGH Switch.

Mid-Market Access Switches

If your environment does not require full Cisco StackWise-480 performance, Cisco Catalyst 9200 and 9200L series switches offer cost-effective alternatives. Examine the Cisco C9200-48PXG Switch, Cisco C9200-NM-4G Network Module, or the high-port-density Cisco C9200L-24PXG-4X Switch.

High-Speed Core & Aggregation

For aggregation, core campus networking, or high-density server rooms, inspect fiber-focused and multi-gigabit core switches like the Cisco C9300X-48TX Switch or the Cisco C9300X-48HX Switch.

Frequently Asked Questions (FAQ)

1. What is the main difference between Cisco C9300-48P and C9300-48T?

The C9300-48P supports full 48-port Power over Ethernet Plus (PoE+), supplying power directly to connected devices such as IP phones and wireless access points. The C9300-48T is a data-only model without PoE output.

2. Can I stack the C9300-48P with Catalyst 9200 Series switches?

No. Stacking requires identical series hardware. Cisco C9300 switches use StackWise-480/1K technology and cannot stack directly with Catalyst 9200 switches (which use StackWise-160/80).

3. Does the C9300-48P include default network uplinks?

The base C9300-48P switch chassis requires a modular uplink network module (purchased separately or configured at order) such as 4x 1G, 4x 10G, 8x 10G, or 2x 40G modules.

4. Does NexoGet ship Cisco products internationally from Dubai?

Yes, NexoGet provides global shipping with secure packaging and complete customs documentation for international orders.
