The Cisco CBS350-24P-4G is a layer-2+/layer-3 managed switch in the Cisco Business portfolio, designed for small to medium business deployments that require advanced features (VLANs, QoS, routing, PoE) but at a more affordable tier than full enterprise Catalyst switches. It supports 24 Gigabit Ethernet ports with PoE+ and 4 Gigabit SFP uplink ports. The switch is fanless (in many variants) and supports IPv4/IPv6 routing, robust security, stacking, and management via Cisco’s Business Dashboard or traditional CLI/GUI.
The “-IN” suffix suggests this is an India region version (e.g. power supply / regulatory compliance), but the core hardware features are the same as global CBS350-24P-4G.
Because it is part of the Cisco Business line, it is intended to combine relatively advanced switching capabilities with easier deployment and management for business networks.
Here is a product listing for reference:
Cisco CBS350‑24P‑4G
Below are some of the standout features and capabilities that make the CBS350-24P-4G suitable for business deployments:
| Feature Category | Details / Benefits |
|---|---|
| PoE / Power | 24 ports support PoE+ (IEEE 802.3at) — useful for powering access points, IP phones, cameras, etc. |
| Switching & Performance | Switching capacity and packet forwarding performance sufficient for mixed traffic scenarios. |
| Layer-2 and Layer-3 Support | Supports dynamic and static routing (e.g. RIP v2), policy-based routing, VLANs, DHCP server/relay, IPv6, and other L3 capabilities. |
| VLAN & Multicast Support | Full VLAN support (802.1Q, private VLAN, Q-in-Q, selective Q-in-Q), multicast via IGMP snooping/querier/proxy, MVR (Multicast VLAN Registration). |
| Link Aggregation & Redundancy | Supports IEEE 802.3ad / LACP, up to 8 LAG groups, up to 8 ports per group, etc. |
| Stacking / Scalability | Hardware stacking up to 4 units (managing up to ~200 ports as one system) with failover. |
| Security & Access Control | Features such as ACLs, 802.1X authentication, private VLAN, dynamic VLAN assignments, loop detection, UDLD, etc. |
| Management & Monitoring | Web GUI, CLI, SNMP, Cisco Business Dashboard integration. Helps with zero-touch deployment of devices like IP phones, APs, etc. |
| Energy Efficiency | Support for energy-saving modes, cable-length detection, etc. |
| Reliability | Fanless design (in this model) = quiet operation and fewer moving parts. |
Here is a summary of more detailed specs drawn from Cisco’s data sheet and published documentation:
| Specification | Value / Detail |
|---|---|
| Ports | 24 × 10/100/1000 RJ-45 with PoE+ support 4 × Gigabit SFP uplink ports |
| Switching Capacity / Forwarding Rate | ~56 Gbps switching capacity ~41.66 Mpps forwarding (64-byte packets) |
| CPU / Memory | ARM CPU 800 MHz 512 MB RAM |
| Buffer / Queues | Internal packet buffer, hardware queues (typically 8 queues) |
| PoE Budget / Power Consumption | Worst-case power consumption ~ 34–35 W (for non-FP variant) Power budget for PoE: depends on model (check local/regional spec) |
| Operating Conditions | Operating temperature: –5 to 50 °C (23° to 122 °F) Storage temp: –25 to 70 °C Humidity: 10% to 90% noncondensing |
| Acoustic / Reliability | Fanless (i.e., no internal fan) → silent operation MTBF: ~ 698,220 hours @ 25 °C |
| Certifications | UL-62368, CSA, CE, FCC Class A etc. |
| Layer 3 / Routing | Static routes (IPv4), RIP v2, Policy-Based Routing, DHCP server/relay, IP interfaces on VLANs, etc. |
| VLAN / Multicast | Up to 4,094 VLANs, Q-in-Q, selective Q-in-Q, VLAN mapping, IGMP snooping, MVR, etc. |
| Stacking | Up to 4 units, managed as a single system |
