Extreme 5520 48-port 90W PoE switch

The Extreme 5520-12MW-36W is a managed network switch delivering 48 Power over Ethernet ports compliant with 802.3bt 90W. It targets enterprises and campuses needing high-density power for wireless access points, cameras and IoT endpoints without separate electrical cabling.

12 multi-rate ports plus dual QSFP28 stacking

Twelve ports operate at 100M, 1, 2.5 and 5GBASE-T while thirty-six ports provide 10/100/1000BASE-T, all MACsec-capable. Two unpopulated QSFP28 ports enable 200Gb stacking of up to eight units using qualified cables or transceivers. Base software license, three fan modules and a VIM slot are included; two modular PSU bays remain empty for chosen power supplies.

PoE budget scales with installed power supplies

A single 715W supply yields 464W PoE budget, dual 715W supplies yield 1049W, while dual 2000W supplies at 200-240VAC deliver 3549W. Maximum chassis draw reaches 4095W. Buyers needing higher port density or non-PoE uplink options should evaluate other models.

Questions about this item

How often do the three fan modules need cleaning or replacement in a dusty rack?

The chassis ships with three hot-swappable fan modules; Extreme does not publish a fixed service interval, so plan inspection every six months and replace any module that shows bearing noise or reduced airflow.

Which resource saturates first when all 48 PoE ports run at 90 W continuously?

The PoE power budget is the limiting factor — with two 2000 W supplies at 200-240 VAC the switch delivers 3549 W, enough for 39 ports at 90 W, so the 40th device would exceed the budget before port bandwidth or stacking links are saturated.

What are the typical heat output and acoustic levels when the switch operates 24/7 with dual 2000 W PSUs?

Maximum draw is 4095 W, so nearly all of that becomes heat in the rack; with dual 2000 W PSUs the fans run at higher speed to maintain the 44 mm chassis temperature, producing noticeable but data-centre-typical noise.
