Cisco Catalyst 9200L-48P-4G-A Switch: High-Performance, Energy-Efficient Access Switching

1. Product Overview

The Cisco Catalyst 9200L-48P-4G-A is a fixed-configuration, 48-port Gigabit Ethernet switch designed for access layer deployments. It provides full Power over Ethernet Plus (PoE+) support on all 48 ports, delivering up to 30W per port to power devices such as IP phones, wireless access points, and IoT endpoints. This switch is part of the Cisco Catalyst 9200 Series, which brings intent-based networking capabilities to a broader range of deployments with enhanced security, resiliency, and simplified operations.

Key highlights of the Catalyst 9200L-48P-4G-A include:

• 48 x Gigabit Ethernet PoE+ ports with 4 x 1G fixed uplinks
• Up to 740W PoE budget with a single power supply; supports dual power supplies for redundancy
• ENERGY STAR® certified for energy efficiency
• Cisco IOS XE Software for advanced automation and security
• StackWise-80 support for scalable stacking up to 8 units

2. Key Features

• Full PoE+ support on all 48 ports
• Fixed 4 x 1G uplink ports
• Cisco IOS XE Software with model-driven programmability
• StackWise-80 technology for virtual stacking
• Enhanced security with MACsec encryption, Trustworthy Solutions, and Cisco Umbrella integration
• Cloud management via Cisco Catalyst Center or Meraki dashboard
• ENERGY STAR certified for reduced power consumption

3. Technology & Standards

The Catalyst 9200L-48P-4G-A supports a wide range of industry standards and protocols, including:

• IEEE 802.3af/at (PoE/PoE+)
• IEEE 802.1Q (VLAN)
• IEEE 802.1X (Network Access Control)
• IEEE 802.1s/w (MSTP/RSTP)
• IPv4/IPv6 routing (static, RIP, OSPF, EIGRP stub)
• MACsec (AES-128) encryption
• SNMP, NETCONF, RESTCONF, YANG

4. How It Works

The switch operates at the network access layer, connecting end-user devices and providing power and data over Ethernet. It uses Cisco's UADP 2.0 Mini ASIC for high-performance forwarding and supports advanced features like QoS, ACLs, and Flexible NetFlow. With StackWise-80, multiple switches can be stacked to operate as a single logical unit, simplifying management and increasing resiliency.
