Hallitsematon kytkin KTI Networks KFS-1640-L

The Unmanaged Switch KTI Networks KFS-1640-L is a compact 16-port RJ-45 Ethernet switch designed for straightforward network deployment. It provides basic switching functionality, supports full- and half-duplex flow control, and complies with IEEE 802.3, 802.3u, 802.3x and 802.3az standards. With an 8,000-entry MAC address table and a wide input voltage range, the switch is suitable for simple, reliable connectivity in industrial and commercial environments.

Advantages

The KTI Networks KFS-1640-L offers auto MDI/MDI-X on copper ports, transparent forwarding for tagged and untagged frames including IGMP and RSTP/STP packets, and support for Energy Efficient Ethernet (IEEE 802.3az). It supports IEEE 802.3x flow control for full-duplex links and back-pressure for half-duplex operation. The device accepts a wide DC input voltage range (including +4.5 to +50 VDC and 110 VDC options), has industrial-rated emission and immunity performance, and can be mounted on DIN-rail or a panel for flexible installation.

Suitable for

• Small office and retail networks requiring unmanaged switching
• Industrial environments with wide temperature and power requirements
• Basic network segmentation and device connectivity (IP cameras, workstations, printers)
• Environments where simple plug-and-play Ethernet connectivity is needed

How to use

Install the KFS-1640-L on a DIN-rail or secure it to a panel using the supplied brackets. Connect Ethernet devices to the RJ-45 ports; the ports automatically negotiate speed and MDI/MDI-X. Use a suitable DC power source within the supported voltage range (+4.5 to +50 VDC or 110 VDC) and connect to the designated power input. No configuration is required for basic operation—devices will communicate through the switch according to standard Ethernet protocols.

Recommendations

Place the switch in a well-ventilated location within the specified operating temperature range and use properly rated power cabling. For deployments requiring managed features, VLANs, or QoS, consider a managed switch instead. Regularly verify firmware and hardware condition in industrial installations and ensure grounding and surge protection where necessary.
