Description

Signamax SI30040 Industrial Gigabit PoE+ Switch with 2 SFP Ports

Overview

The Signamax SI30040 is an industrial-grade, unmanaged Gigabit switch designed to reliably power and connect IP devices in demanding environments. With 8x 10/100/1000Mbps PoE+ ports and 2x 1000Mbps SFP uplink ports, this switch is engineered for surveillance deployments where consistent power and high-bandwidth uplinks are critical for cameras, access control readers, and other network-connected equipment. Its rugged construction ensures operation in challenging conditions, making it suitable for factory floors, outdoor enclosures, or transportation hubs.

Compatibility

This switch is compatible with any standard IEEE 802.3af/at compliant PoE device, including most IP cameras, wireless access points, and VoIP phones. The 1000Mbps SFP ports allow for high-speed fiber optic uplinks to network backbones or other switches, supporting standard SFP modules for various fiber types and distances. It integrates seamlessly into existing network infrastructure without requiring complex configuration.

Installation Notes

The SI30040 supports standard 802.3at PoE+ power delivery, providing up to 30W per port, with a total PoE budget of 120W. It requires a 48-57VDC power input (power supply sold separately). The unit is designed for DIN rail mounting and operates within an extended temperature range of -40°C to 75°C (-40°F to 167°F), suitable for harsh industrial settings.
