2.1.5 Plug the power cord into the outlet on the wall and check if the power LED lights up. If it lights up, then the hub is ready to be connected to the network, as shown in Figure 2-5. Figure 2-5 Power on the hub and make it ready 2.2 Installing the hub on your working surface You have to find a solid working surface to place the hub and make sure the equipment is not close to any high voltage power source or over-heated... - Page 13 Figure 2-6 Lay hub on stable desktop 2.2.2 If you are installing more than one hub, please turn off the power of all hubs first. Then you can get another hub and place it above the previous one on the working surface, as shown in Figure 2-7. Finally, put the stacking kit in the middle of two sides and click into the stacking hole in the plastic housing.
- Page 14 2.2.3 Get the stackable cable and connect the cable to the stacking connector on the hub, as shown in Figure 2-8. Connect "Down" SCSI port of the upper hub to "Up" SCSI port of the lower hub. Any loose connection of the stackable cable will cause problems with network performance and quality.

You can observe the LED status to see if the hub works fine. The meanings of LEDs are defined in section 2.4.1. -
Page 18: System Status Indicators
There are three groups of LED indicators in the front panel: • System status indicators: Indicate the overall system status of the hub. It includes system PWR, Fan Err., Master, Slave indicators, Collision of 10 and 100M, and Bridge function •... -
Page 19: Network Status Indicators
Note: It's normal either Master or Slave LED will display when hubs are stacking. Note:The difference between Master hub and Slave hub will be explained in chapter 3. Collision: Indicate if a collision occurs in 10Mbps or 100Mbps domain. Bridge: Indicates if the bridging function is enabled. Note: The slave hub will provide a Bridge Uplink Port, see chapter 3 for details. -
Page 20: Network Utilization Indicators
Figure 2-15 Network Status Indicators 100/10: Indicates if the port is working at 100Mbps or 10Mbps. LNK/Rx: Indicates if the port is linked to another port or receiving data. Partition: Indicates if the port is partitioned or not. A port is partitioned if it experiences consecutive collisions. - Page 21 Figure 2-16 Network utilization indicators The number of utilization is in percentage. For example, "15" of "100M" means 15% of 100Mbps, "55+" of "10M" means the utilization is more than 55% of 10Mbps. 2-13 User's Manual...

Up-Link port. Please turn over the page to see the different Topologies. 3.1 Network topology for AcerHub ALH-608ds : The factors for ALH-608ds dual-speed network implementation are: • For stand-alone one, the ALH-608ds consists of separate 10Mbps and 100Mbps network domains with one built-in switch to inter-connect the data in domains, as shown in Figure 3-1. - Page 23 Figure 3-2 Master and Slave hubs in stacking ALH-608ds. Note: 1. To concern the convenience of the cross-wiring connection between hubs, ALH-608ds provide 1 normal port (marked as "II) and 1 cross-over port (marked as "X"). These 2 ports are wired to each other by different wiring assignments.

10Mbps network speed when connecting to 10Mbps Ethernet hubs and 100Mbps network speed if connected to 100Mbps hubs. • If multiple ALH-608ds are stacked together, users can connect to hubs by the uplink port in slave hubs. Therefore other hubs can perform another class-II cascading, as shown in Figure 3-6. - Page 26 10/100Mbps Ethernet switching ports and it will work at 10Mbps network speed if connected to 10Mbps switching ports. Figure 3-7 Connect to Ethernet Switches. No matter if the ALH-608ds hubs are stacked together or not, the user always can connect to Ethernet switches by the uplink port. User's Manual...
