3. IP Address Setting

3-1 VN-E4with Factory Default Settings

Refer to START-UP GUIDE on procedures for setting the IP address when VN-E4is in the factory default settings.

3-2 VN-E4for which IP address is known

When the IP address of VN-E4is known, it can be changed by accessing the built-in web page of VN-E4via the PC’s Internet Explorer. See A5. Setting Using Internet ExplorerB.

3-3 When IP address of VN-E4is unknown

When IP address of VN-E4 is unknown, there are 3 methods to know IP address.

a)Use the search tool

The search tool in attached CD-ROM is available to know IP address of VN-E4.Refer readme file of the tool for detailed information.

b)Initialize VN-E4

Pushing [RESET] button on rear panel over 5 seconds initializes VN-E4to factory default setting.

c)Capture packets on network

Perform following procedures to find out the IP address of VN-E4.

1. Configuration for looking up IP address

Set up a PC with the network monitor software installed on it. The network monitor software will capture and look up incoming packets at the PC. An example of free network monitor software that may be obtained from the Internet is Ethereal. Connect VN-E4,the switching hub and PC using a straight LAN cable of Category 5 and above. (Do not connect the DHCP server to the switching hub.)

2. Capturing packets sent by VN-E4

Launch the network monitor software on the PC and start capturing.

Supply power to VN-E4using the AC adaptor. Depending on the settings, the amount of time required for VN-E4to start up may vary from about 1 to 2 minutes. VN-E4will start packet transmission during this interval, and capturing will end in about 2 minutes.

3. Looking up captured packets

●If ARP request is sent first by VN-E4

If the following ARP request is sent first by VN-E4,then the destination IP address of this packet will be the IP address of VN-E4.(In this case, the subnet mask of VN-E4is unknown.)

Packet type: ARP request

Source IP address: 100.100.254.169

This ARP request packet is used to check whether there are devices that possess a duplicate IP address with VN-E4.In this case, ADHCPB and APPPoEB of VN-E4are set to AOffB.

●If the DHCP Discover packet is sent first by VN-E4

The DHCP client function of VN-E4is set to ON. In a LAN environment without a DHCP server, the DHCP will time out in about 2 minutes after the power is turned on, and VN-E4will be started up using the following IP address.

IP address 192.168.0.2 Subnet mask 255.255.255.0 Default gateway 192.168.0.254

●If the following broadcast packet is sent first by VN-E4Destination MAC address 0xFFFFFFFFFFFF Ethernet Type 0x8863

The APPPoEB of VN-E4is set to AOnB. In a LAN environment without a PPPoE server, it will time out in about 2 minutes after the power is turned on, and VN-E4will be started up using the following IP address.

IP address 192.168.0.2 Subnet mask 255.255.255.0 Default gateway 192.168.0.254

4.IP address setting on PC

The subnet mask of VN-E4is unknown when methods 1. to 3. are used to look up the IP address, and there is a possibility that this may be 255.255.255.254.

Set the IP address of the PC such that it is in the same segment with VN-E4.(Example 1) When the IP address of VN-E4is 10.1.2.2

By setting the PC’s IP address to 10.1.2.3 and the subnet mask to 255.255.255.0, they will be in the same segment and communication will be enabled even if the subnet mask of VN-E4is 255.255.255.254.

(Example 2) When the IP address of VN-E4is 10.1.2.3

By setting the PC’s IP address to 10.1.2.2 and the subnet mask to 255.255.255.0, they will be in the same segment and communication will be enabled even if the subnet mask of VN-E4is 255.255.255.254.

Whether communication is enabled may be determined by sending a Ping from the PC to the IP address of VN-E4.

For procedures on changing settings of VN-E4via Internet Explorer on the PC, refer to A5. Setting Using Internet ExplorerB.
