Unmanaged Network Switch Longshine LCS-2.5GS7105 — 5× Gigabit Ethernet (10/100/1000), Black, 16000 MAC

Longshine LCS-2.5GS7105 is an unmanaged, wall-mountable network switch with five Gigabit RJ-45 ports that support 10/100/1000 Mbps operation and auto-negotiation up to 2.5 Gbps when connected devices and cabling allow. Designed for plug-and-play deployment, this compact black switch implements IEEE 802.3ab/802.3az/802.3bz/802.3u/802.3x standards and holds a 16,000-entry MAC address table to manage MAC-level forwarding in small office and home LANs. The fanless design and solid capacitors target reliable silent operation and extended service life.

Advantages

The Longshine LCS-2.5GS7105 provides simple, unmanaged switching with multi-speed auto-negotiation (10/100/1000 and 2.5G where supported) to upgrade network throughput without replacing existing CAT5e cabling. Energy Efficient Ethernet support and Green Ethernet functions reduce power consumption during low activity. A substantial MAC address table and support for full-duplex flow control improve handling of simultaneous traffic streams while physical features such as LED indicators, loop detection and an LED on/off switch aid basic troubleshooting.

Suitable for

• Small offices requiring reliable wired LAN connectivity for workstations, NAS and VoIP phones
• Home networks upgrading some devices to 2.5 Gbps over existing CAT5e/CAT6 cabling
• Simple, unmanaged expansions of a backbone switch or home router
• Silent environments where fanless operation is preferred (studios, meeting rooms)

When it may not be suitable

This unmanaged switch does not provide VLANs, QoS configuration, SNMP or other managed features; it is therefore not suitable for networks requiring granular traffic segmentation, centralized monitoring or advanced security policies. Environments that need 10 Gbps ports or enterprise-class routing and switching features should select a managed or higher-speed product.

• Power-saving: Energy Efficient Ethernet and Green Ethernet functions
• Design: Fanless, solid capacitors, wall-mount support, black enclosure
• Additional features: Loop detection, LED indicators with LED on/off switch

How to use

Install the Longshine LCS-2.5GS7105 on a wall or place it on a stable surface and connect the switch to power. Use standard Ethernet cables to connect computers, NAS, routers or other networked devices to the RJ-45 ports. The switch will automatically negotiate link speeds (10/100/1000 and 2.5G where supported) and manage forwarding using its MAC address table; no configuration is required. Use the LEDs to verify link status, activity and link speed, and enable loop detection or turn off LEDs using the dedicated switch if needed.

What to consider before purchase

• Verify whether 2.5G speeds are required and supported by connected devices and cabling (CAT5e or better recommended)
• Confirm that unmanaged switching (no VLAN/QoS/management) meets your network requirements
• Ensure the number of ports and physical mounting options match your installation needs
• Consider power and placement for optimal cooling despite fanless design

Usage recommendations

Use the LCS-2.5GS7105 as a simple, quiet access switch to aggregate desktops, access points and storage devices to a local backbone. For best 2.5 Gbps performance, use CAT5e or CAT6 cabling and verify connected NIC support. Place the switch in a ventilated area and periodically check LEDs and connections; for networks that require segmentation, monitoring or traffic shaping, choose a managed switch instead.
