Managed 48-port 1GbE PoE switch

The Extreme Networks 5520-48W is a managed edge and aggregation switch built for digital enterprise networks. It provides 48 autosensing 10/100/1000BASE-T ports with 802.3bt PoE capability and MACsec support. Two unpopulated QSFP28 stacking ports and a serial console port complete the fixed I/O. It suits IT teams needing high-density wired connectivity with integrated power delivery.

PoE budget and stacking headroom

The switch delivers up to 3568W of PoE budget when equipped with two 2000W power supplies, supporting 30W, 60W and 90W devices such as wireless APs, PTZ cameras and smart lighting. Stacking bandwidth reaches 200Gbps across up to eight units, while the MAC table scales to 114,688 addresses. Systems requiring more than 48 powered ports or uplink speeds beyond 50G will need additional switches or a different platform.

Universal hardware with modular uplinks

The 5520 series uses a universal hardware platform that lets operators choose between ExtremeXOS and Switch Engine operating systems. Modular uplink slots accept 10G, 25G and 50G transceivers for flexible aggregation links. Management options include on-premises and cloud-based consoles. The fixed 48-port copper layout means fibre-only deployments or densities beyond 48 endpoints require other models.

Questions about this item

Will the 48 1GbE PoE ports power my existing 802.3af and 802.3at devices without reconfiguration?

The 48 10/100/1000BASE-T ports support 802.3bt up to 90W and are backward compatible with 802.3af and 802.3at endpoints, so legacy phones, cameras and access points will negotiate the correct power level automatically.

Which front-panel LEDs confirm that the two stacking links and the 3568W PoE budget are active after power-on?

The stacking/QSFP28 ports show link and activity LEDs when a QSFP28 module is inserted and a stack cable is connected, while the system power and PoE LEDs indicate that both 2000W PSUs are delivering up to 3568W to the 48 ports.

Are the two QSFP28 uplink transceivers and the stacking cables included, or must they be purchased separately?

The two stacking/QSFP28 ports are unpopulated, so 10G, 25G or 50G transceivers and compatible stacking cables are not included and must be sourced separately.
