Zyxel GS-1116 EE [12/30] Features

Dimension GS-1116/GS-1124 Gigabit Switch

1-2 Getting to Know the GS1116/GS-1124

Both ports 15 and 16 in the GS-1116 (or 23 and 24 in the GS-1124) support 3.3V Mini GBIC. The

GBIC port auto detects between Giga copper and Mini GBIC. The Mini GBIC module is optional.

When the Mini GBIC module is not installed, these act as Giga copper connections.

The switch is an ideal solution for solving traffic block at the core of the network. It offers auto-

negotiation 100/1000Base-T Gigabit Ethernet ports that can significantly improve your network

backbone performance.

1.2.1 IEEE 802.1p Class of Service

The IEEE 802.1p Class of Service (CoS) provides two queues for high and low priority traffic. This

improves network efficiency and performance by giving higher priority to outgoing traffic. The lower

queue has a priority value in the range of zero to three and the higher queue has a priority value in the

range of four to seven.
