Cisco Catalyst 9200 Series Switch - C9200-48P-E

1. Product Overview

The Cisco Catalyst 9200-48P-E is a high-performance, 48-port Gigabit Ethernet switch designed for enterprise access layer deployments. It provides full Power over Ethernet Plus (PoE+) support, delivering up to 30W per port to power devices such as IP phones, wireless access points, and IoT endpoints. This model is part of the Catalyst 9200 Series, which brings intent-based networking capabilities to a broader range of deployments with enhanced security, resiliency, and simplified management.

Key selling points:

• 48 x Gigabit Ethernet ports with full PoE+ support
• Network Essentials license included
• StackWise-160 support up to 160 Gbps stacking bandwidth
• Cisco IOS XE Software for advanced automation and security
• Energy-efficient design with ENERGY STAR® certification available on select models

2. Key Features

• Full PoE+ support on all 48 ports (up to 740W with single PSU, 1440W with dual PSU)
• Modular uplink options (4x1G, 4x10G, 2x25G, 2x40G)
• Field-replaceable power supplies and fans for enhanced resiliency
• Cisco StackWise-160 technology for virtual stacking of up to 8 units
• Advanced security features including MACsec encryption and Trust Anchor technologies
• SD-Access support for policy-based automation
• Cloud management capability via Cisco Catalyst Center or Meraki dashboard

3. Technology

The Catalyst 9200 Series switches utilize Cisco's UADP 2.0 Mini ASIC with integrated CPU, providing optimized performance and scalability. They support various technologies including:

• IEEE 802.3af/at PoE/PoE+
• IEEE 802.1AE MACsec encryption (AES-128)
• IEEE 802.1Q VLAN
• IEEE 802.1s/w Spanning Tree Protocols
• Cisco StackWise-160 technology
• Cisco IOS XE Software with model-driven programmability

4. Working Principle

The Catalyst 9200-48P-E operates as an access layer switch, connecting end devices to the network infrastructure. It uses hardware-based forwarding through the UADP 2.0 Mini ASIC for high-performance switching. The switch can operate as a standalone unit or as part of a stack using StackWise-160 technology, which combines multiple physical switches into a single logical entity with unified management.

For Power over Ethernet functionality, the switch incorporates intelligent power management that dynamically allocates power to connected devices based on their requirements, with per-port power monitoring and management capabilities.

5. Applications

The C9200-48P-E is ideal for various enterprise environments:

• Enterprise campus access layer deployments
• Branch office networks
• Educational institutions and classrooms
• Healthcare facilities for connecting medical devices
• Retail environments supporting POS systems and digital signage
• IoT deployments with multiple powered devices

9. Frequently Asked Questions

Q: What is the difference between Network Essentials and Network Advantage licenses?
A: Network Essentials provides basic Layer 2 and static routing features, while Network Advantage adds advanced capabilities including dynamic routing (OSPF, EIGRP, BGP), advanced security, and network segmentation.

Q: Can the C9200-48P-E be stacked with other Catalyst 9200 models?
A: Yes, it can be stacked with other C9200 models using StackWise-160 technology, but not with C9200L or C9200CX models due to different stacking architectures.

Q: What is the maximum PoE power available with dual power supplies?
A: With dual PWR-C6-1KWAC power supplies, the switch can deliver up to 1440W of PoE power.

Q: Does this switch support cloud management?
A: Yes, the Catalyst 9200 Series can be managed through Cisco Catalyst Center (formerly DNA Center) or cloud-monitored via the Meraki dashboard.

10. Precautions

• Ensure adequate airflow and clearance around the switch for proper ventilation
• Verify power requirements when connecting high-power PoE devices
• Use only compatible Cisco network modules and power supplies
• Follow local electrical safety regulations during installation
• For stacking configurations, use only approved StackWise cables
• Comply with environmental operating conditions (0°C to 45°C operating temperature)
