Product Features
24-Port PoE+ for High-Density Deployments
The EX2028-P includes 24 RJ45 Gigabit Ethernet ports with IEEE 802.3af/at PoE+ support, delivering up to 30 watts per port. This makes it ideal for powering Cambium Wi-Fi access points, VoIP phones, smart sensors, and surveillance equipment in enterprise and campus environments.
4 x 10G SFP+ Uplink Ports
Four high-speed SFP+ uplinks provide robust fiber connectivity for uplinks or stacking, ensuring fast data transfer to core switches or servers and reducing network bottlenecks.
Advanced Layer 2 and Layer 3 Switching
Supports both Layer 2 and Layer 3 features including VLANs, static routing, policy-based routing, link aggregation, IGMP snooping, and Quality of Service (QoS) to optimize traffic management and network segmentation.
400-Watt Total PoE Power Budget
With a total PoE budget of 400 watts, the EX2028-P can power multiple high-demand PoE devices simultaneously without external power injectors or midspan solutions.
cnMaestro Cloud or On-Premises Management
Integrates with Cambium’s cnMaestro platform for centralized management, configuration, monitoring, and automated device provisioning from anywhere—ideal for distributed networks.
Enhanced Network Security
Built-in security features include port-based 802.1X authentication, DHCP snooping, MAC address filtering, dynamic ARP inspection, and role-based access control, helping prevent unauthorized network access and attacks.
Intelligent Policy Automation
The EX2028-P supports policy-based configuration automation, automatically assigning VLANs and access policies based on device type or user credentials, reducing manual effort and configuration errors.
Designed for Enterprise and Campus Networks
Built for high availability and performance, this switch includes redundant internal fans, robust metal enclosure, and support for rack-mount installation in network closets or data centers.
