Zyxel GS-105B v3 Unmanaged L2+ Gigabit Ethernet (10/100/1000) Silver

Optimized for Smooth VoIP and Data Exchange
The ZyXEL GS-105B v3 5-Port Desktop Gigabit Ethernet Switch connects network devices and the home network at blazing Gigabit speed. The newly designed QoS ports guarantee smooth transfer for bandwidthintensive applications such as VoIP and data communications.

Compact, sturdy switch with alternative wall-mount design
The GS-105B v3 fits any environment. Regardless of desktop or wallmount installation, its sturdy, compact design provides more flexibility for wired home networks.

Fast, reliable wired connectivity
Without any manual configuration, the GS-105B v3 can boost data transfer speed for connected network devices such as IP phones, network storages, PCs and laptops to the network at blazing-fast Gigabit speed.

Optimized for smooth VoIP and data exchange
The GS-105B v3 has 3 QoS ports with an assigned high- and mediumpriority mechanism to enhance the stability of VoIP and data exchange. Just connect network devices such as IP phones, PCs, laptops or network storages to the high-priority or medium-priority ports of your choice, you can then enjoy smooth VoIP communication and data transfer at the same time.

Green switch saves energy
Compliant with the IEEE 802.3az Energy Efficient Ethernet standard, the GS-105B v3 provides power-saving benefits without compromising performance. The GS-105B v3 can automatically adjust power consumption according to the number of active, connected network devices and cable length; that is, it consumes less power if fewer network devices are connected and active, or when the length of Ethernet cable is shorter.

Zyxel GS-105B v3. Switch type: Unmanaged, Switch layer: L2+. Basic switching RJ-45 Ethernet ports type: Gigabit Ethernet (10/100/1000), Basic switching RJ-45 Ethernet ports quantity: 5. Full duplex. MAC address table: 20000 entries, Switching capacity: 10 Gbit/s. Networking standards: IEEE 802.3, IEEE 802.3ab, IEEE 802.3az, IEEE 802.3u, IEEE 802.3x

How to use

Connect the GS-105B v3 to your router or existing network using one of the Gigabit RJ-45 ports, then plug other network devices such as IP phones, NAS, PCs or laptops into the remaining ports. The switch is unmanaged and requires no configuration—it will automatically negotiate link speed and duplex settings. Use the designated high- and medium-priority QoS ports for devices that need more stable VoIP or data performance.

Recommendations

For optimal energy savings and performance, place the switch where cable runs are as short as practical and connect latency-sensitive devices (IP phones, streaming/network storage) to the QoS-priority ports. Ensure proper ventilation around the metal housing and mount on a wall if desktop space is limited.
