Industrial DIN-rail switch

The Black Box LIE402A is an unmanaged 4-port PoE++ switch designed for industrial networks. It mounts on a standard DIN rail and operates from a 46–57 VDC supply, delivering up to 60 watts per RJ-45 port. Two SFP slots accept 100 or 1000 Mbps fibre transceivers for uplink flexibility.

Installers needing rugged PoE++

This unit suits cabinet builders and automation engineers who must power cameras, wireless APs or sensors in harsh environments without a fan. The –40 to +75 °C range and vibration-resistant construction fit outdoor enclosures and factory floors. Sites that require managed features such as VLANs, SNMP or port mirroring should select a managed alternative.

60-watt PoE++ per port

The decisive specification is IEEE 802.3bt compliance with 60 watts available simultaneously on all four copper ports. A 56 VDC, 4.46 A source is required to sustain that budget. If connected devices need only 15.4 or 30 watts, the switch still negotiates the correct class automatically.

Questions about this item

Will the LIE402A power my existing IEEE 802.3af cameras that only draw 15.40 watts alongside newer PoE++ devices?

Yes, the switch complies with IEEE 802.3af, IEEE 802.3at and IEEE 802.3bt, so each RJ-45 port negotiates the correct class and delivers up to 60 watts while safely supplying 15.40-watt legacy gear.

How do I confirm the switch is forwarding traffic and supplying PoE++ on all four RJ-45 ports after mounting it on the DIN rail?

Connect powered devices to each port; the port LEDs will show link and PoE status, and the fanless unit will operate silently within its -40 to 75°C industrial range.

Does the package include SFP transceivers for the two 100/1000-Mbps SFP slots, or must I buy them separately?

The box contains the LIE402A switch, a +/-46 to +/-57 VDC power adapter and a DIN-rail clip; SFP transceivers are not included and must be purchased separately.
