Cisco Business CBS110-8T-D Full English Product Description

1. Product Overview

• 8: 8 copper Gigabit RJ45 ports
• T: Non-PoE copper ports
• D: Compact desktop form factor powered by external DC wall adapter, no built-in rack-mount power module
  This cost-effective layer 2 switch delivers full wire-speed non-blocking Gigabit switching for PCs, printers, NAS storage, surveillance NVRs and non-powered Wi-Fi access points. It adopts silent passive heat dissipation, compact lightweight metal casing, energy-efficient IEEE 802.3az EEE hardware, built-in basic L2 features and automatic network optimization, ideal for entry-level small business networks without dedicated IT staff.

2. Hardware Port Specifications

• Downlink Ports: 8 × auto-sensing 10/100/1000BASE-T RJ45 copper ports, non-PoE, compatible with Cat5e / Cat6 cabling, auto MDI/MDI-X
• Uplink Interfaces: No dedicated SFP fiber slots; all 8 RJ45 ports support uplink interconnection to core switches or routers
• Management Interfaces: No console port, no Web UI, no Bluetooth (fully unmanaged plug-and-play device)
• LED Indicators: Separate front-panel LEDs for power status, per-port link activity and 10/100/1000Mbps speed identification
• Hardware Reset Button: No dedicated reset button; power cycle to restore factory default state
• Cooling Architecture: Fanless passive heat sink design with zero operational noise, suitable for libraries, classrooms and medical spaces
• Power Key Note: Powered by external DC wall adapter (marked "-D"); zero PoE power budget for all copper data ports

5. Built-in Unmanaged Layer 2 Switching Functions

• Transparent IEEE 802.1Q VLAN pass-through, compatible with managed upstream VLAN networks
• Automatic STP loop detection to eliminate Layer 2 broadcast flooding and network loops
• IEEE 802.3ad LACP uplink aggregation pass-through support for multi-port bandwidth bundling
• IGMP Snooping v1/v2/v3 multicast optimization to reduce bandwidth waste for IPTV and multi-camera surveillance streams
• Embedded cable diagnostic tool to detect short circuits, open lines and cable length faults without third-party testers
• Automatic port power saving: Disables transceiver power when no end device is connected

6. Built-in Basic Network Security Mechanisms

• Dynamic MAC address learning limit to block malicious MAC flooding attacks
• Broadcast storm suppression to prevent network paralysis from abnormal broadcast packets
• Hardware-based port isolation to isolate sensitive workstations and prevent cross-terminal data leakage
• Short-circuit surge protection for all RJ45 ports to avoid hardware burnout from damaged Ethernet cables

7. Hardware QoS Intelligent Traffic Prioritization

• 4 independent hardware priority queues per Gigabit port
• Automatic DSCP / 802.1p CoS traffic classification without manual configuration
• Port ingress/egress bandwidth rate limiting to avoid single-port bandwidth congestion
• Prioritizes VoIP voice and real-time surveillance video packets to minimize latency and jitter

8. Multi-Scenario Deployment Advantages

• Zero configuration: Unbox, plug in power and Ethernet cables for instant connectivity
• Dual mounting modes: Desktop placement or wall-mounted under desks, cabinets and kiosks
• Ultra-low power consumption and fanless silent design for noise-sensitive indoor environments
• Wide operating temperature tolerance for warehouse, retail counter and kiosk deployment
• Universal compatibility with all mainstream PCs, IP phones, surveillance cameras and wireless access points
• No centralized management software required, reduces small business operation costs

9. Typical Application Scenarios

• Small office non-PoE workgroup interconnection for staff PCs, printers and desktop terminals
• Retail convenience stores and self-service kiosks for cash registers and basic surveillance cameras
• Home offices, design studios and mini quiet labs without high-bandwidth PoE demands
• School auxiliary classrooms and libraries requiring silent network hardware
• Distributed IoT sensor aggregation deployed outside centralized wiring closets
• Temporary conference room network expansion for laptops and presentation equipment
