Page 5: About This Manual
Express Ethernet Switch LB9019A-R2 About This Manual This manual describes how to install and use LB9019A-R2: 16 Ports QoS Switch. The switch introduced here auto-negotiates the presence of 10/100Mbps and full/half-duplex mode. To get the most out of this manual, you should have an understanding of networking concepts such as bridging, IEEE 802.3 Ethernet, 100BASE-TX/FX Fast Ethernet, and local area networks (LANs). -

Qos Status Port Status Power Figure 2: LB9019A-R2: Front Panel LEDs Power This LED comes on when the switch is properly connected to power and turned on. Port Status The RJ-45 ports numbered from 1 to 16 in one section on the 16 Ports QoS Switch. -
Page 7: Physical Ports
Express Ethernet SwitchLB9019A-R2 QoS (Quality of Service) Status The LEDs displaying status for Layer 3 IP Header priority, Layer 2 VLAN Tagging priority, and Port 1~6 Port based priority. Before you use this table for troubleshooting, make sure the switch is properly connected to power and turned on. -
Page 8: Qos (Quality Of Service) Settings
Express Ethernet SwitchLB9019A-R2 QoS (Quality of Service) Settings Figure 3: Default Setting of the QoS (Quality of Service) DIP Switch on the Rear Panel There are three Priority Queues on 1616Q, Normal (N), High (H), and Very High (VH) Queues. On the rear panel of the switch, there are eight pins on the DIP Switch for QoS (Quality of Service) Settings. - Page 9 Express Ethernet SwitchLB9019A-R2 If PIN 7 is ON, the 3-bit CoS of tagged VLAN will decide which queue the packet to join. Packets with CoS (Class-of-Service) bits of 000(or 0) are sent to Normal Queue, 001(or 1) to High Queue, and 010 or higher (2 or higher) to Very High Queue. If PIN 8 is ON, the ToS (Type-of-Service) byte in IP header will decide which queue the packet to join.
