Διαχειριζόμενο L2/L3 Gigabit Ethernet Switch Cisco C9200-48PXG-E

The Cisco C9200-48PXG-E is a managed L2/L3 Gigabit Ethernet switch with 48 PoE+ RJ-45 ports, designed for enterprise and branch-office access. It supports IEEE networking standards and provides a 16,000-entry MAC address table, modular uplinks, stacking up to 160 Gbps, and hardware and software features from the Cisco Catalyst 9200 Series to deliver resilient, secure, and programmable network connectivity.

Advantages

The switch combines full PoE+ capability with power and fan redundancy, intent-based networking features and open APIs of Cisco IOS XE. It offers UADP ASIC programmability, Layer 3 feature support, cold patching and a broad set of security functions that protect hardware, software and traffic passing through the device. These characteristics help simplify IT operations and provide investment protection for future innovations.

Suitable for (tasks / use cases)

• Enterprise access layer connectivity for wired devices
• Branch-office networks requiring PoE+ for IP phones, wireless access points and cameras
• Environments needing Layer 2/Layer 3 switching with stacking and modular uplinks
• Deployments that require programmability and integration with Cisco Digital Network Architecture

How to use

Install the switch in a standard 19-inch rack using the provided mounting brackets and connect the uplink ports to the aggregation or core layer. Connect endpoints to the 48 Gigabit PoE+ RJ-45 ports for data and power delivery. Configure management access via the CLI, web interface or open APIs on Cisco IOS XE. Use stacking and modular uplinks as required to expand capacity and enable high-availability topologies. Apply security and Layer 3 policies according to network design.

Recommendations

For best results, plan PoE power budgets per switch and enable redundant power and fan modules where available. Keep Cisco IOS XE up to date and follow Cisco’s configuration guides to leverage intent-based networking, automation and UADP programmability while maintaining security baselines.
