Adafruit

Adafruit 28 Port Gigabit PoE Switch 2 in 1 Accessory

SKU CH-VQ4Y-VAMH4

A 28-port Gigabit PoE switch delivering up to 30W per port across 24 PoE ports with a 400W total budget, plus two uplink ports and two SFP slots

  • 28 Gigabit ports deliver high-speed wired connectivity for every device
  • 24 PoE ports supply up to 30W each over a single cable
  • 400W total PoE budget powers cameras, access points and VoIP phones together
  • One-Key VLAN isolates ports 1-24 from each other while linking them to uplinks 25-26
  • Industrial-grade fans keep the metal chassis cool and quiet under continuous load

28-Port Gigabit PoE Switch

The switch provides 24 PoE-enabled RJ45 ports plus two uplink Gigabit ports and two 1G SFP slots. It delivers data and power over a single cable for devices such as IP cameras or wireless access points. The unit is unmanaged and requires no configuration.

Thermals Noise and Power Draw

Industrial-grade fans handle heat dissipation while keeping noise low during continuous operation. The metal casing aids thermal performance across a range of ambient temperatures. Total PoE budget reaches 400 W with up to 30 W available per port.

400 W PoE Budget

The 400 W power budget determines how many powered devices can run simultaneously. Buyers who need more total PoE capacity should consider a higher-budget model. The One-Key VLAN feature isolates ports 1-24 from each other while allowing communication with ports 25-26.

Questions about this item

How do I install the switch and which step is often missed?

Plug in the power cord and network cables; the step often missed is enabling the One-Key VLAN mode to isolate ports 1-24 from each other while allowing communication with ports 25-26.

What maintenance or replacement will the switch need later?

The built-in industrial-grade fans may require cleaning or replacement over time to maintain effective heat dissipation and low noise operation.

What limit appears first under sustained heavy PoE load?

The 400 W total PoE budget across all 24 ports is the first limit reached when multiple devices draw near the 30 W per-port maximum.
