ZyXEL GS-105B v2, GS-108B v2 Specifications

The ZyXEL GS-105B v2/GS-108B v2 5/8-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 bandwidth-intensive applications such as VoIP and data communications.

Benets

Compact, sturdy switch with alternative wall-mount design

The GS-105B v2/GS-108B v2 ts any environment. Regardless of desktop or wall-mount installation, its

sturdy, compact design provides more exibility for wired home networks.

Fast, reliable wired connectivity

Without any manual conguration, the GS-105B v2/GS-108B v2 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 v2/GS-108B v2 has 3/4 QoS ports with an assigned high- and medium-priority 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 Ecient Ethernet standard, the GS-105B v2/GS-108B v2

provides power-saving benets without compromising performance. The GS-105B v2/GS-108B v2 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.
