3.3  Connecting to AC2000 via Wired Ethernet

The S3030 can be connected via a Clarinet EtherUSB hub, as per the diagram below:

Figure 10 Connection to AC2000 using USB hub

Perform the steps given in the following sections to establish a connection with AC2000.

3.3.1  Assign DHCP address to EtherUSB hub

The Clarinet EtherUSB hub must be assigned a DHCP address. It is a prerequisite that a 
DHCP network exists to enable this step to be performed:

1.

Power up the EtherUSB hub. LED display:

(PWR): Solid, then slow flash, but a fast flash indicates hub fault

• UPLINK: solid green (for network link)

2.

Connect the EtherUSB to a network switch that is connected to the DHCP server.

3.

Open a workstation that is connected to the same DHCP network.

4.

Run Clarinet’s EA104 DevFinder application (available from the Download section of the 
Clarinet Systems website) or another similar Network Discovery Tool to find all newly 
added devices on the DHCP network.

5.

From the list of newly added devices, confirm the Clarinet EtherUSB hub is displayed. 

The model number EA104 and serial number as displayed on the EtherUSB unit is displayed.

6.

Write down the IP address that has been assigned to the device from the DHCP network, 
as this will be needed for the next step.

3.3.2  Assigning a Static IP address to EtherUSB hub

7.

Launch an internet browser and navigate to: http://<HUB-IP-Address>:9876/

Replace the text <HUB-IP-Address> with the static IP address assigned by the DHCP server 
in the previous step.
