Product identity

The Extreme Networks 5420M-48W-4YE is a managed stackable switch providing 48 copper ports that support 10/100/1000BASE-T with 802.3bt 90 W PoE plus four 1/10/25G SFP28 uplinks and two SFP-DD stacking ports. It ships with base software and dual-persona OS capability.

Deployment fit

Network teams needing high-density 90 W PoE for access points, cameras or IoT endpoints and wanting cloud or on-premises management via Extreme Platform ONE will match this model. Sites that require only lower PoE budgets or purely fibre access ports should evaluate other platforms.

Deciding specification

The 48 ports all deliver up to 90 W under IEEE 802.3bt, so the total PoE power budget required by the connected devices determines whether this switch meets the installation.

Questions about this item

What uplink speed do the four SFP28 ports actually deliver?

The four SFP28 uplink ports run at 1, 10 or 25 Gbps each, giving up to 25 Gbps per port depending on the transceiver used.

What rack space and clearance does the 442 mm wide chassis need?

It fits a standard 19-inch rack, occupies 1 U at 43.2 mm high and 330.2 mm deep, and weighs 5.36 kg so the rack must support that load.

How do I stack two of these switches and which ports do I use?

Use the two unpopulated SFP-DD stacking ports with qualified SFP+/SFP-DD direct-attach cables or transceivers; up to eight switches can be stacked when running Switch Engine.
