Core Specifications of the Cisco 1783-CMS6B
The Cisco 1783-CMS6B is a 6-port managed industrial Ethernet switch optimized for compact, harsh environments. Built as part of Cisco’s Stratix 5000 series, it features 4x 10/100/1000BASE-T PoE+ ports and 2x 1G SFP uplinks, operates in -40°C to 70°C, and supports Layer 2 management for VLANs, QoS, and security policies.
Key Differentiators vs. Generic Industrial Switches
| Feature | 1783-CMS6B | Basic Industrial Switches |
|---|---|---|
| Port Power Capacity | 30W per PoE+ port | 15–18W per port (typical) |
| Management | Cisco IOS CLI/WebUI | Limited SNMP-only control |
| Cybersecurity | MACsec, TACACS+, ACLs | Basic password protection |
| Certifications | UL 61010, ATEX Zone 2, IEC 62443-4-2 | Limited to IP ratings |
Industrial Applications
- Factory Automation: Connects PLCs, HMIs, and sensors in confined control cabinets.
- Renewable Energy: Deploys in solar/wind substations with temperature resilience and surge protection.
- Transportation Hubs: Powers IP cameras, access control, and signage in terminals.
Addressing Critical User Questions
Q: Can the 1783-CMS6B operate in explosive environments?
Yes—its ATEX Zone 2 certification ensures safe use in areas with flammable gases or dust.
Q: Does it support legacy devices with 10/100Mbps speeds?
All 4 copper ports auto-negotiate 10/100/1000Mbps, ensuring backward compatibility.
Q: How is redundancy handled?
Supports Rapid Spanning Tree Protocol (RSTP) and dual redundant power inputs (12–48VDC).

Final Assessment
The 1783-CMS6B fills a critical niche for small-scale industrial networks where space and harsh conditions are constraints. While its port count is lower than the 1783-CMS20DB, its PoE+ power budget and Cisco-grade security make it a smarter long-term investment than cheaper, unmanaged alternatives. For teams already embedded in Cisco’s ecosystem, it’s a no-brainer.
