large network,refer section 3.1 for details.) • Built-in switch auto-disable function to avoid data looping when stacking • External switching power supply for lower power consumption and heat emission • Compact design for SOHO desktop environment for easy networking 1.
This chapter will guide you through how to install the AcerHub ALH-608ds. It includes procedures for connecting to the external power supply, installing the hub on your working surface, connecting the Hub to your computer, and guidelines to see if it works well.
2.1.2 Place the hub on the desktop and remove the packing box of the power adapter, as shown in Figure 2-2 . 2-2 User's Manual Figure 2-1 Get the hub and power adapter Figure 2-2 Put the hub on d.
2.1.3 Verify it's a 5V,3A power adapter by looking at the indicating label. If the adapter is correct, please stretch the cable and plug the cord into the power jack of the hub, as shown in Figure 2-3 . 2.1.4 Once the hub is connected to the power adapter, please connect the power adapter to a power cord, as shown in Figure 2-4 .
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 .
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.
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.
2.3 Connecting to computers 2.3.1 Make sure the hub is ready for networking by checking if the PWR indicator displays. 2 . 3 . 2 See if the computer is working and find the RJ-45 connector of the adapter card in computers.
2.3.3 Arrange the route for cabling if no fixed cabling box is provided. Otherwise, It's right way to connect from your computer to the fixed cabling box on your working surface and plug the other end of the cable to the RJ-45 connector on the hub, as shown in Figure 2-11 .
2.3.5 If you are trying to connect more cables to the hub, please follow procedures from section 2.3.2 to 2.3.4. 2.4 Does the hub work well? You can observe the LED status to see if the hub works fine. The meanings of LEDs are defined in section 2.4.1.
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.
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.
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.
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.
This chapter describes the network topology for hybrid 10Mbps and 100Mbps networks, cabling requirement for connections, the interoperability between hubs and switches and the function of bridge Up-Link port. Please turn over the page to see the different Topologies.
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.
• By way of an uplink port with a Bridge function, the limitations on 100Mbps hub count(maximum 2) can be eliminated. The hub count is unlimited and cable length between hubs can reach 100meters, as shown in Figure 3-4 . Figure 3-4 Unlimited cascading of ALH-608ds.
• The data in 10Mbps or 100Mbps domain will be inter-connected by internal built-in switch in the Master hub consequently. • All hubs delivering data by the shared-bus always work on half-duplex mode; that is, data can be sent or received at one time in one direction.
3.2.2 Connecting to Ethernet Switches : The factors governing hub and switch interconnection are: • The hubs are only connected to Ethernet switches by an uplink port.
