Overview of the CBS250-48PP-4G-AU
The CBS250-48PP-4G-AU is a Cisco Business 250 Series switch engineered for environments demanding high Power over Ethernet (PoE) density. With 48 PoE+ ports and 4 Gigabit SFP uplinks, it caters to businesses deploying IP cameras, wireless access points, and VoIP systems at scale, such as schools, hospitals, or enterprise campuses.
Core Technical Specifications
- Port Configuration: 48 x 10/100/1000BASE-T PoE+ ports + 4 x 1G SFP uplinks.
- PoE+ Budget: 400W total power—supports up to 30W per port (IEEE 802.3at).
- Layer 3 Lite Features: Static routing, inter-VLAN routing, and IPv4/IPv6 dual-stack support.
- Security: 802.1X authentication, ACLs, and port isolation.
- Management: Cisco Business Dashboard and mobile app for real-time monitoring.
Addressing Critical User Concerns
Q: How many PoE+ devices can the CBS250-48PP-4G-AU power simultaneously?
A: With 400W total PoE budget, it can support ~16 devices at 25W each (e.g., PTZ cameras) or ~33 low-power devices like VoIP phones.
Q: Is this switch suitable for high-bandwidth applications like video surveillance?
A: Yes. The 4 SFP uplinks enable fiber connectivity for high-throughput backhaul, while QoS prioritizes video traffic to minimize latency.
Q: Can it integrate into an existing Cisco network?
A: Absolutely. It supports Cisco Discovery Protocol (CDP) and works seamlessly with other Cisco switches and routers.
