2. Official Product Overview

The Cisco CBS250-16P-E-2G is the EU regional variant of CBS250-16P-2G smart switch, marked with suffix "-E" for European standard power cord and regional compliance certification, designed for small-to-medium businesses, European retail stores, branch offices, classrooms and IP surveillance deployments that require integrated data and PoE power delivery over single Ethernet cablesCisco.

This cost-effective smart switch delivers enterprise-class switching performance, complete Layer 2 feature toolkit, native embedded Layer 3 static routing, multi-layer network security and user-friendly graphical web management. It eliminates the need for separate power adapters for PoE endpoints, supporting unified deployment of VoIP phones, Wi-Fi 6 access points, PoE IP cameras and thin clients.

Equipped with 16 IEEE 802.3at PoE+ Gigabit RJ45 ports plus 2 independent 1G SFP fiber uplink slots, it provides 18 total Gigabit Ethernet interfaces. Powered by an 800MHz ARM processor, 512MB DRAM and 256MB flash storage, it delivers 36 Gbps switching capacity and 26.78 Mpps wire-speed forwarding rate for 64-byte frames, supporting smooth concurrent surveillance streaming, multi-user file sharing and video conference traffic without congestion. The internal power supply supplies a 120W total PoE budget, with each copper port capable of outputting up to 30W for high-power PoE devices.

Port security, static MAC address binding, automatic blocking of unauthorized network terminals
DoS attack suppression, multi-layer ACL traffic filtering to block malicious access
Encrypted management channels: HTTPS web GUI, SSH CLI, SNMPv3 secure remote monitoring
Syslog event logging, built-in cable diagnostic tools, mandatory password complexity policy
Independent guest network isolation to protect internal confidential business data

7. Energy-Saving Green Technologies

IEEE 802.3az Energy Efficient Ethernet (EEE): auto power reduction for idle Ethernet links
Dynamic power tuning based on cable length to cut unnecessary power loss
Port LED dimming or full shutdown mode for unmanned wiring closets
Low-power fanless hardware design with low heat generation, extended service lifespan

8. Multi-Mode Local & Remote Management

Intuitive graphical web management interface (HTTP/HTTPS) with basic & advanced operation modes
Dual console access: serial RJ45 + mini USB port for offline local CLI configuration
SSH secure remote command line management
SNMP v1/v2c/v3 compatible with third-party network monitoring platforms
TFTP / offline USB firmware upgrade, SNTP time synchronization, ping & traceroute diagnostic tools
