Switch Cisco CBS350-48T-4X-EU — 48 x Gigabit Ethernet RJ‑45 ports, 4 x 10Gb SFP+ uplinks, managed

The Cisco CBS350-48T-4X-EU is a rack-mountable 19" managed switch with 48 Gigabit Ethernet RJ‑45 ports and four 10Gb SFP+ uplink ports. It provides layer 2/3 Lite features, QoS and VLAN support, and can be managed via web GUI or CLI. The model does not support PoE and is intended for small-to-medium business and campus network deployments to aggregate wired endpoints, servers and wireless access points while offering increased uplink capacity and centralized control.

Advantages

This managed switch delivers a high port density with 48 Gigabit Ethernet ports plus four 10Gb SFP+ uplinks for flexible uplink and stacking topologies. Layer 2/3 Lite capabilities enable basic routing between VLANs, while QoS and VLAN features support traffic segmentation and prioritized services. Web and CLI management options provide centralized configuration and monitoring suitable for IT administrators. The 1U rack form factor and standard 19" mounting make it suitable for structured rack installations.

Suitable for

• SMB and branch office networks requiring centralised wired connectivity
• Campus and education networks aggregating endpoints and access points
• Server aggregation and uplink to core switches or routers
• Environments needing VLAN segmentation and QoS without PoE

How to use

Install the switch in a standard 19" rack using the supplied mounting brackets and secure power connections according to your rack layout. Connect wired devices to the 48 RJ‑45 ports and use the four 10Gb SFP+ ports for uplinks to core switches or for high-speed aggregation. Access the device configuration through the web GUI for common tasks such as VLAN setup, QoS policies and port configuration, or use the CLI for scripted or advanced configurations. Monitor switch status and performance from the management interface and apply firmware updates as provided by Cisco.

Usage recommendations

For best performance, use high-quality SFP+ transceivers certified for the CBS350 series, plan VLANs and QoS rules before deployment, and ensure the switch firmware is kept up to date. Do not expect PoE capability; provide separate power or PoE-enabled switches where required for powered devices.
