24-port PoE+ switch with 370W budget

The Extreme Networks X435-24P-4S is a rackmount managed Layer 2 switch that provides 24 RJ45 ports at 10/100/1000BASE-T speeds, each delivering up to 30W under IEEE 802.3at and 802.3bt Type 3 standards. Four unpopulated SFP slots support 1G or 2.5G uplinks, and the unit ships with one AC power supply and a rack-mount kit. The total PoE power budget is 370W.

Suited for PoE edge deployments needing cloud

This switch fits networks that power access points, cameras or phones through 30W ports and manage them via ExtremeCloud IQ or ExtremeCloud IQ – Site Engine. It also supports Extreme Fabric Connect for automated fabric services. It is not for buyers who need Layer 3 routing, larger MAC tables or a deeper PoE budget for higher-power devices.

370W total PoE budget across 24 ports

The 370W pool is the single figure that determines how many powered devices can run simultaneously at their required wattage. Each port can supply up to 30W, so the budget covers a limited number of full-power endpoints; calculate your device draw against this limit before purchase.

Questions about this item

What rack space and clearance does the 43.94 mm high X435-24P-4S need?

It fits a standard 1U rack opening (43.94 mm high, 441.96 mm wide) and is 254.00 mm deep; allow rear clearance for the AC power cord and front clearance for the 24 RJ45 and 4 SFP cables.

Which step is often missed when installing the X435-24P-4S?

The included rack-mount kit XN-2P-RMKIT-004 must be attached before sliding the 3.48 kg unit into the rack; skipping the brackets leaves the switch unsecured and blocks the front ports.

What component will need replacement first on the X435-24P-4S?

The single internal AC PSU is the only field-replaceable part; fans are fixed, so a PSU failure is the first maintenance event.
