Unmanaged Network Switch Longshine LCS-GS7105-E — 5 x Gigabit RJ-45 Ports, Black

The Longshine LCS-GS7105-E is an unmanaged desktop network switch with five Gigabit RJ-45 ports supporting 10/100/1000 Mbit/s. It supports automatic MDI/MDI-X, auto-negotiation and full- and half-duplex operation on all ports. The switch uses store-and-forward switching with error filtering and supports Jumbo Frames up to 12K. Its compact desktop form factor and included wall-mount kit make it suitable for home and small office installations.

Advantages

The switch delivers up to 1 Gbit/s per port with automatic flow control (IEEE 802.3x) and back-pressure handling for half-duplex links, reducing packet loss and improving network reliability. Energy Efficient Ethernet (IEEE 802.3az) helps lower power consumption. Built-in LEDs and loop detection assist with basic network diagnostics, while an internal MAC address table of 2000 entries supports straightforward traffic forwarding in small networks.

Suitable for

• Expanding wired connectivity in home networks
• Small office LANs requiring a simple unmanaged switch
• Connecting workstations, printers and network storage at Gigabit speeds
• Environments needing a compact desktop or wall-mounted switch

When it may not be suitable

This unmanaged switch offers no VLAN, QoS, or advanced management features, so it is not suitable for networks that require traffic segmentation, granular bandwidth control, or remote configuration. It also does not support 10 Gigabit Ethernet; environments needing higher-than-Gigabit throughput should consider managed or higher-speed switches.

Key specifications

• Ports: 5 × 10/100/1000 Mbit/s RJ-45
• Switching method: Store-and-Forward
• Duplex: Full and Half duplex support
• Auto features: Auto-negotiation and Auto MDI/MDI-X
• Flow control: IEEE 802.3x (flow control) and back-pressure
• Jumbo Frames: up to 12K
• MAC address table: 2000 entries
• Energy: IEEE 802.3az (Energy Efficient Ethernet)
• Form factor: Desktop with wall-mount kit
• Diagnostics: LED indicators, loop detection

How to use

Place the switch on a flat surface or mount it on a wall using the supplied kit. Connect each device to any RJ-45 port with standard Ethernet cables (Cat5e or higher recommended for Gigabit). Connect the supplied 5 V DC power adapter to power the unit. Ports will auto-negotiate link speed and duplex; monitor the front-panel LEDs for link and activity status. No configuration is required for basic operation.

What to consider before purchase

• If you need VLANs, QoS, SNMP or remote management, choose a managed switch instead
• Ensure your cabling is Cat5e or better to achieve Gigabit speeds
• Check power requirements and available AC outlet for the 5 V DC adapter
• Confirm 1 Gbit/s per-port capacity is sufficient for your use case

Usage recommendations

For reliable Gigabit performance connect critical devices (PCs, NAS, routers) using Cat5e or Cat6 cables, place the switch in a ventilated spot, and use the wall-mount kit where desk space is limited. Monitor LEDs for link/activity and replace cables or reposition devices if link speeds are lower than expected.
