This page explains the troubleshooting procedures to resolve problems you may experience while installing DS-520AN.
DS-520AN is not displayed in the search result of the Device Server Setup
When
DS-520AN is not displayed in the search result of Device Server Setup,
the cause need to be determined from the installation status, network
environment, and status of computer used for the configuration of
DS-520AN.
Solution

Please check the LED status of DS-520AN and the Ethernet Hub DS-520AN
is connected to. If the LED indicates improper status, replace the AC
plug and other cables, and reboot the connected devices. |
Solution

Solution
|
During the initial configuration, place DS-520AN and computer in the same network segment.
|
Solution
|
Please select Obtain an IP address automatically at Internet Protocol (TCP/IP) Properties of the computer.
Otherwise connect the computer and DS-520AN with a crossover cable or to the standalone Ethernet Hub and see how it works.

How should I determine the way to assign an IP address to DS-520AN?
There are two ways to assign an IP address to DS-520AN; one is to Get IP address automatically from DHCP server and the other is to Assign IP address manually. Choose the way to assign an IP address according to your environment.
Solution
|
You can use Get IP address automatically from DHCP server. As DS-520AN is set by default to Get IP address automatically, DS-520AN will obtain an IP address appropriate to your network environment from the DHCP server just by powering up DS-520AN.
Refer to Resetting to Factory Defaults for details on how to reset DS-520AN to the factory default settings.

Solution
|
Please use DHCP Server feature of DS-520AN or Assign IP address manually. Keep in mind of the following points regarding the IP address to assign to DS-520AN.
-
Assign an IP address unique in the network.
-
Assign an IP address that has the same address class as the computer that will use DS-520AN.
e.g. When an IP address of the computer is "192.168.0.xx", assign an
address such as "192.168.0.100" that is not used by other network
devices.
(Tips about the IP address)
-
An IP address is a unique number for identifying network devices. An IP
address is indicated with four numbers divided by a period (.), for
example "192.168.0.1". The integer from 0-255 is used for each number.
-
An IP address is, depending on the number assigned, categorized to 3 classes below.
-
Numbers making up the IP address are either network numbers indicating network, or host numbers
indicating each network device; each number indicates the different
meaning based on the IP address class. Each class is categorized as the
following diagram which is indicating a network number as n, and a host number as u. An IP address with the same network number must be assigned to the network devices in the same network segment.
-
There is an address range in the IP address called the private address
that could be used freely. In the LAN environment not directly
connected to the internet, an IP address is assigned within the range
of the private address.
