Network switch EXTREME 5420M 24-port PoE, 24 SFP fiber ports, model 5420M-24W-24S-4YE

The EXTREME 5420M 24-port PoE, 24 SFP fiber ports (model 5420M-24W-24S-4YE) is a stackable access/distribution switch engineered for campus and branch networks. It combines 24 PoE-capable RJ45 copper ports for powering devices with 24 SFP fiber ports for uplinks and direct fiber connections. The design supports mixed-media deployments where IP phones, wireless access points and surveillance cameras coexist with fiber aggregation, offering a compact platform for enterprise edge networking.

Advantages

This switch provides integrated Power over Ethernet on all copper ports alongside a large number of SFP fiber interfaces, enabling flexible deployment of powered devices and fiber connectivity without separate injectors or intermediate modules. Stackability allows multiple units to operate as a single logical switch for simplified management and higher aggregated capacity. The platform is suited for environments that require a combination of high-density PoE and extensive fiber connectivity while maintaining standard enterprise feature support for access and distribution layer services.

Suitable for

• Enterprise access layer for desktop and IP telephony connectivity
• Wireless access point backhaul and PoE provisioning for APs
• IP camera deployments and video surveillance edge aggregation
• Campus or branch fiber aggregation and uplink consolidation

Key specifications

• 24 RJ45 ports with Power over Ethernet support for connected powered devices
• 24 SFP fiber ports for multi-mode or single-mode transceivers (fiber uplinks and links)
• Stackable form factor for creating a unified logical switch across multiple units
• Designed for access and distribution layer deployments in enterprise and campus networks

How to use

Install the switch in a standard 19-inch rack or on a flat surface following equipment mounting guidelines. Connect powered devices such as IP phones, wireless access points or cameras to the RJ45 PoE ports; connect fiber uplinks or links to the SFP ports using compatible optical transceivers and appropriate cabling. Configure stacking and network services via the vendor management interface or supported network management tools to integrate the switch into the existing topology and apply VLANs, QoS and security policies appropriate to the deployment.

Usage recommendations

Plan PoE budget according to the power class of connected devices and distribute high-power devices across the stack to avoid exceeding per-unit power capacity. Use quality SFP transceivers and verify fiber type and distance requirements before installation. Monitor device temperatures and stacking status through management tools to maintain consistent performance in enterprise access and distribution roles.
