CAMBIUM NETWORKS Cnmatrix Ex1028 Ethernet-switch

The Cambium Networks cnMatrix EX1028 is a managed L2/L3 Gigabit Ethernet switch in a 1U rack-mountable form factor. It provides 24 Gigabit RJ-45 ports and 4 SFP slots for fiber connectivity, a MAC address table capacity of 16,000 entries, and adherence to multiple IEEE networking standards for reliable layer‑2 functionality and enhanced access security. The grey chassis and compact 1U design are intended for efficient network management and scalable deployment in rack environments.

Advantages

The cnMatrix EX1028 delivers full Layer 2 capabilities with managed features and enhanced access control, reducing provisioning and management time. Its combination of 24 Gigabit RJ‑45 ports and 4 SFP modules supports mixed copper and fiber connectivity. Compliance with common IEEE standards ensures interoperability and predictable behavior in enterprise and service-provider networks. The switch’s 1U rack design and moderate weight simplify installation and integration into existing racks.

Suitable for

• Top-of-rack switching in small to medium data closets
• Access-layer deployments in enterprise and branch networks
• Environments requiring mixed copper and fiber uplinks
• Managed networks that need IEEE-standard features and enhanced access security

How to use

Mount the cnMatrix EX1028 in a standard 19‑inch rack using appropriate rack ears or brackets. Connect copper devices to the 24 RJ‑45 Gigabit ports and attach fiber uplinks or modules to the 4 SFP slots as required. Access the switch management interface via the console, web GUI, or supported management protocols to configure VLANs, access control, spanning tree, link aggregation, and other Layer 2/Layer 3 features. Save configuration and monitor port status and logs to maintain network stability.

Recommendations

Use the switch in ventilated rack spaces to ensure adequate cooling, keep firmware up to date for security and interoperability, and plan VLANs and access control policies before deployment to reduce provisioning time.
