The Zy XEL GS-108B supports intelligent power-saving technology as most other Ethernet switches were designed to supply full power on all ports regardless of the status of connected computers. The GS-108B is intelligent enough to sense the status of computers on each port & to adjust power allocation to achieve the best energy-saving performance. Unlike other switches that set unnecessarily high power output level to the longest cable length, the GS-108B is able to detect the actual length of cables on each port & adjust its power output accordingly. Zy XEL GS-108B not only comes with reliable performance, but also the commitment to energy saving for environment. Zy XELs GS-108B 10/100/1000 Mbps desktop switches are designed for reliable high-performance networks. Thanks to the non-blocking switching fabric in full-duplex mode, the Store-&-Forward service brings low-latency & error-free packet delivery. With these features, the transmission efficiency can be boosted dramatically. With the N-way auto-negotiation function, the GS-108B automatically connects to its network counterparts with the highest possible network speed & activates duplex mode automatically. All it takes to enliven your network is just plugging in the cable, & no manual configuration is required. The stylish compact metal housing fits any working environment. GS-108B comes with different port configurations for affordable & reliable SOHO network expansion needs.
