Cisco ONS-SC-2G-53.3=: Extended-Reach Optical
Product Overview and Functional Role The �...
The Cisco CBS350-48T-4G-NA is a 48-port Layer 2 managed switch built for North American businesses requiring high-density connectivity, PoE+ flexibility, and robust security. Tailored for environments like campuses, warehouses, or large offices, it balances scalability with operational simplicity. Below, we explore its technical merits and address common deployment considerations.
Core Features Optimized for NA Demands
- 48 x Gigabit Ethernet Ports: Connects desktops, printers, and IoT devices with wire-speed performance.
- 4 x 1G SFP Uplinks: Supports fiber or copper uplinks for extending network reach or connecting to core switches.
- PoE+ Budget (370W Total): Powers up to 48 devices like VoIP phones (6–10W) or basic IP cameras (7–15W), though total capacity limits simultaneous high-power use.
- NA Compliance: Designed for 120V AC operation, certified for FCC/UL standards, and optimized for 60Hz power grids.
Technical Specifications
| Attribute | Detail |
|---|---|
| Switching Capacity | 104 Gbps |
| PoE Budget | 370W (15.4W per port, max 30W) |
| Noise Level | <32 dB (fanless at idle) |
| Dimensions | 440 x 445 x 44 mm |
Answering Critical User Questions
Q: Can this switch power 48 PoE+ devices at full capacity?
No. The 370W total budget means only ~7.7W per port if all 48 ports are active. Prioritize low-power devices (e.g., VoIP phones) or stagger high-power loads (e.g., 30W APs) to avoid overloading.
Q: Are SFP uplinks necessary for small offices?
For single-site setups with basic traffic, 1G copper uplinks suffice. However, SFP fiber uplinks benefit multi-building campuses or environments with EMI interference.
Q: How does it handle network threats?
Port security, MAC-based access control, and 802.1X authentication lock down access, while storm control prevents broadcast floods.
Deployment Recommendations
- Best For:
- Schools or offices needing 40+ wired connections with basic PoE.
- Retail chains centralizing inventory databases across locations.
- Avoid If:
- You require 10G uplinks or Layer 3 routing (e.g., inter-VLAN routing).
- Your use case demands 740W+ PoE budgets for high-power devices.
Final Perspective
After evaluating Cisco’s technical documentation and real-world setups, the CBS350-48T-4G-NA is a pragmatic choice for NA organizations prioritizing port density over raw power. Its 370W PoE+ budget suits environments with moderate power needs, though larger deployments may require supplementary switches.
