Cisco Catalyst C9200L-48T-4X-E Switch: High-Performance, Fixed Uplink Access Switch

1. Product Overview

The Cisco Catalyst C9200L-48T-4X-E is a 48-port Gigabit Ethernet data switch designed for access layer deployments requiring reliable performance, essential Layer 3 features, and energy-efficient operation. Part of the renowned Catalyst 9200 Series, this switch offers fixed 4x1G/10G SFP+ uplinks, robust security, and support for Cisco DNA Essentials software. It is an ideal solution for medium to large enterprises, campuses, and branch offices seeking a cost-effective, scalable, and easy-to-manage networking infrastructure.

2. Key Features

• 48 x 10/100/1000 Mbps RJ-45 data ports
• 4 x 1/10G SFP+ fixed uplinks
• StackWise-80 support (up to 80 Gbps stacking bandwidth)
• Cisco DNA Essentials with Network Essentials license
• Energy Efficient Ethernet (EEE) and ENERGY STAR® certified
• Enhanced security with MACsec, ACLs, and Cisco Trust Anchor
• Plug and Play (PnP) for zero-touch deployment
• Cloud monitoring via Meraki dashboard

3. Core Technologies & Standards

The C9200L-48T-4X-E leverages Cisco IOS XE software for advanced automation, programmability, and security. It supports:

• IEEE 802.3az (Energy Efficient Ethernet)
• IEEE 802.1Q (VLAN tagging)
• IEEE 802.1x (Network Access Control)
• IEEE 802.3ad (Link Aggregation)
• IPv4/IPv6 routing (static, RIP, OSPF stub)
• MACsec encryption (AES-128)
• NETCONF/YANG for model-driven programmability

4. How It Works

The switch operates at the network access layer, connecting end-user devices, IP phones, and wireless access points. It uses hardware-based forwarding (UADP 2.0 Mini ASIC) to deliver wire-speed performance. Traffic is classified and prioritized using QoS policies, and security is enforced through ACLs and segmentation. The switch can be stacked with other C9200L models to form a single logical unit, simplifying management and increasing resiliency.

9. Frequently Asked Questions

Q: Can this switch be stacked with other Catalyst 9200 models?
A: No, it can only be stacked with other C9200L models using StackWise-80.

Q: Does it support PoE?
A: No, the C9200L-48T-4X-E is a data-only switch. For PoE, consider the C9200L-48P-4X-E.

Q: What is the difference between Network Essentials and Advantage?
A: Essentials includes basic Layer 3 (static, RIP), while Advantage adds advanced routing (OSPF, EIGRP) and segmentation.

Q: Is cloud management included?
A: Yes, it can be managed via Cisco Meraki dashboard with limited visibility under DNA Essentials.

10. Precautions

• Ensure adequate ventilation and operating temperature (0°C to 45°C).
• Use compatible SFP/SFP+ modules only (refer to Cisco compatibility matrix).
• Follow local electrical and safety regulations during installation.
• For stacking, use certified Cisco StackWise cables and ensure software version compatibility.
• Avoid mixing AC and DC power supplies in the same chassis unless specified.
