Cisco Business CBS110-24T Full English Product Description

1. Product Overview

• 24: 24 copper Gigabit access RJ45 ports
• T: Non-PoE data-only copper ports
  No "-D" suffix means it adopts a standard compact 19-inch 1RU rack chassis with built-in internal universal AC power supply, equipped with two dual-purpose 1G SFP/RJ45 combo uplink ports for fiber long-distance aggregation. It delivers wire-speed non-blocking switching for office PCs, printers, centralized NAS storage and non-powered Wi-Fi access points, with silent passive heat dissipation, full native Layer 2 feature set, automatic QoS optimization and built-in hardware security, perfectly matching networks without dedicated IT administrators.

2. Hardware Port Specifications

• Downlink Ports: 24 × auto-sensing 10/100/1000BASE-T RJ45 copper ports, non-PoE, Cat5e/Cat6 compatible, auto MDI/MDI-X cross cable detection
• Uplink Interfaces: 2 × 1G SFP/RJ45 combo dual-purpose ports; support 1G fiber transceivers or copper Gigabit uplink to core routers/switches
• Management Interfaces: No console port, no Web GUI, no Bluetooth (pure unmanaged plug-and-play hardware)
• LED Indicators: Independent front-panel LEDs for power status, port link/activity, 10/100/1000Mbps speed and SFP combo port status
• Hardware Reset Button: No dedicated physical reset button; power cycle to restore factory default configuration
• Cooling Architecture: Fanless passive heat sink design with zero operational noise, suitable for classrooms, clinics and quiet office spaces
• Power Key Note: Integrated internal universal AC power supply (external DC adapter not required); zero PoE power budget for all RJ45 data ports

5. Complete Native Layer 2 Unmanaged Switching Functions

• Transparent IEEE 802.1Q VLAN pass-through, fully compatible with upstream managed VLAN networks
• Automatic STP loop detection to eliminate Layer 2 broadcast flooding and network forwarding loops
• IEEE 802.3ad LACP static/dynamic link aggregation pass-through for uplink bandwidth bundling
• IGMP Snooping v1/v2/v3 multicast optimization to reduce bandwidth waste for IPTV and multi-camera surveillance video streams
• Auxiliary L2 Tools: Built-in cable diagnostic tool, port isolation, broadcast storm suppression, automatic port power saving on link down

6. Embedded Hardware Security Mechanisms

• Dynamic MAC address learning limit to block malicious MAC flooding attacks
• Hardware broadcast storm suppression to prevent network paralysis caused by abnormal broadcast packets
• Port isolation function to isolate sensitive office terminals and avoid cross-port data leakage
• Multi-layer surge & short-circuit protection for all RJ45 copper ports to prevent hardware burnout

7. Automatic QoS Intelligent Traffic Prioritization

• 4 independent hardware priority queues per Gigabit port
• Native auto classification of 802.1p CoS and DSCP marked traffic without manual configuration
• Port ingress/egress bandwidth rate limiting and traffic shaping to avoid single-port bandwidth congestion
• Dedicated high-priority forwarding queue for VoIP voice and low-bitrate surveillance video to minimize latency and jitter

8. Multi-Mode Deployment & Operation Advantages

• Zero configuration deployment: Unbox, plug power and Ethernet cables to activate instant connectivity
• Triple installation modes: Standard rack mounting in wiring closets, desktop flat placement or hidden wall mounting
• Ultra-low power consumption and fully fanless silent design for noise-sensitive indoor environments
• Wide operating temperature tolerance supports retail kiosks, warehouse auxiliary zones and distributed IoT sites
• Universal cross-brand compatibility with mainstream PCs, printers, NAS and non-powered wireless access points
• No centralized management software required, cutting maintenance costs for small businesses

9. Typical Application Scenarios

• Medium-density office non-PoE access layer for bulk staff PCs and fixed desktop terminals
• School main computer labs, libraries and quiet education environments with silent fanless operation
• Chain retail headquarters and shopping mall workstation & centralized NAS interconnection
• Small media design workgroups with high-capacity storage via SFP fiber uplink links
• Remote satellite branch secondary aggregation requiring independent Gigabit fiber uplink to core switches
• Distributed low-bandwidth IoT sensor deployment outside centralized wiring closets without PoE power demands
