Technical Profile of the CB-M12-M12-MMF7M= The CB...
Core Specifications and Target Applications
The CBS220-48FP-4X-AU is a 48-port Layer 2 managed switch built for environments requiring high Power over Ethernet (PoE) density. It offers 48×1G PoE+ ports, 4×10G SFP+ uplinks, and a 740W total PoE budget, making it suitable for powering IP cameras, wireless access points, and VoIP systems across offices, schools, or retail spaces.
Performance and Scalability Constraints
- PoE Allocation: Supports 30W per port (IEEE 802.3at), ideal for demanding devices like PTZ cameras.
- Throughput: Non-blocking switching at 136 Gbps ensures minimal latency for real-time applications.
- Fan Noise: Audible under full load, which may require placement in dedicated comms rooms.
- Stacking: Lacks modular stacking, limiting expansion to daisy-chaining via uplinks.
Addressing Key Deployment Concerns
Q: Does the CBS220-48FP-4X-AU support advanced traffic management?
Yes, it includes VLANs, QoS prioritization (8 queues), and IGMP snooping for multicast traffic optimization.
Q: Can it integrate with existing Cisco networks?
Limited to Cisco Business Dashboard for cloud management; no compatibility with Catalyst DNA Center or SD-Access.
Cost vs. Capability Analysis
Priced lower than Catalyst 9200 series, the CBS220-48FP-4X-AU sacrifices Layer 3 routing and advanced security features like TrustSec. However, its PoE+ capacity and 10G uplinks provide significant value for budget-conscious deployments needing high device density.
Security and Compliance Highlights
- Port Security: MAC address filtering prevents unauthorized access.
- 802.1X Authentication: Integrates with RADIUS servers for dynamic VLAN assignments.
- STP/RSTP: Mitigates loop risks in redundant topologies.
Where to Source Reliable Inventory
For guaranteed authenticity and Cisco’s limited lifetime hardware warranty, “CBS220-48FP-4X-AU” is available exclusively through authorized partners like itmall.sale. Third-party sellers often lack firmware update support, risking compliance gaps.
Final Take: Practicality Over Enterprise-Grade Features
Having configured this model for a mid-sized retail chain, the CBS220-48FP-4X-AU excels in environments where high PoE density and 10G uplinks are non-negotiable, but advanced routing isn’t. Its web-based management simplifies setup for IT generalists, though the absence of CLI may frustrate network engineers accustomed to granular control. For businesses prioritizing cost over future-proof scalability, this switch delivers—provided noise and Layer 3 limitations are acknowledged upfront.
