1. Short Sales Title (For Listing & Quotation)
Cisco CBS250-16T-2G Business 250 Series 16-Port Gigabit Non-PoE Smart Managed Switch, 2 Combo Gigabit SFP/RJ45 Uplink Ports, Layer 3 Static Routing, Fanless 1RU Rackmount Data Switch
2. Official Product Overview
The Cisco CBS250-16T-2G belongs to the Cisco Business 250 Series cost-effective smart switches, specially designed for small and medium businesses, branch offices, retail outlets, and general office wiring closets without large-scale PoE device deployments. It delivers enterprise-class switching performance, complete Layer 2 switching functions, native Layer 3 static routing, robust multi-layer security, and intuitive web management at a budget-friendly price, ideal for data-only office networks including PCs, printers, NAS storage, and wireless access points powered by separate power adaptersCisco.
This non-PoE model is equipped with 16×10/100/1000BASE-T copper RJ45 data ports plus 2 dual-purpose Gigabit combo uplink ports (each supports either RJ45 copper or SFP fiber transceiver), offering a total of 18 Gigabit Ethernet interfaces. Built with an 800MHz ARM processor, 512MB DRAM and 256MB flash storage, it provides 36Gbps switching capacity and 26.78 Mpps wire-speed forwarding rate for 64-byte frames, supporting smooth concurrent data transmission, file sharing, video conferencing and surveillance data streaming without congestion.

Encrypted management: HTTPS web GUI, SSH CLI, SNMPv3 secure monitoring
-
Syslog event logging, cable diagnostic tools, password complexity policy
-
Isolated guest network segmentation to protect internal business data
7. Energy-Saving Green Technologies
-
IEEE 802.3az Energy Efficient Ethernet (EEE): auto power reduction for idle links
-
Automatic power tuning based on Ethernet cable length to cut unnecessary power consumption
-
LED dimming/shutdown function for unmanned wiring closets to save extra power
-
Low-power fanless hardware design with minimal heat generation
8. Multi-Mode Management Options
