ZyXEL Communications GS-105A User manual

Application Diagram
GS-105A/GS-108A
High Performance
With non-blocking switching and full duplex standard, the GS-105A/GS-108A reaches speeds of up to 2000Mbps on
each port, good for today’s and tomorrow’s media-rich applications.
Simple to Use
The GS-105A/108A features auto-sensing 100/1000 Mbps ports that automatically detect the speed and duplex mode of
attached servers, workstations, or hubs. Plug-and-Play functionality makes installation easy and fast.
Smart Features
The IEEE 802.3x standard-based flow control allows the GS-105A/108A to prevent pending traffic congestion by
informing attached devices to stop data transmission. When the switch detects that each port’s buffer is nearly full, the
attached devices are requested to wait until they can accept new data. Meanwhile, support for IEEE802.1p priority tagging
optimizes quality of service.
Durable and Compact Design
The durable metal chassis with its compact design is sized to save space and easily fits on a desk or mounts to the wall.
Flexible installation capabilities make the GS-105A/108A perfect for home and small business applications.
Benefits
ZyXEL 5-port and 8-port Gigabit Ethernet switches provide high flexibility and high bandwidth connectivity to servers,
workstations and other attached devices. With Gigabit connectivity, the GS-105A and GS-108A speed up data
transmission by transferring large files across a network while remaining interoperable with all 10, 100, and 1000Mbps
devices. The compact designs fit easily on a desk or mount easily to a wall, and with true non-blocking switching
capability, are ideal solutions for home and small office network applications.
