Carry out the hardware installation. The hardware installation comprises the connection of the UTN server to the network, the USB device and the power supply; see: 'Quick Installation Guide'.
General Information 1.6 Saving the IP Address in the UTN Server Why IP Addresses? An IP address is used to address network devices in an IP network. TCP/IP network protocols require the storing of the IP address in the UTN server so that the device can be addressed within the network. How Does the UTN Server Obtain IP Addresses? The UTN server is able to assign itself an IP address during the initial installation. Boot protocols are used to assign an IP address automatically to the UTN server.
General Information ZeroConf If no IP address can be assigned via boot protocols, the UTN server assigns itself an IP address via ZeroConf. For this purpose, the UTN server picks an IP address at random from the address range (169.254.0.0/16) which is reserved for ZeroConf. You can use the domain name service of Bonjour for the name resolution of the IP address; see: Ö 42. BOOTP The UTN server supports BOOTP, which means that the IP address of the UTN server can be assigned via a BOOTP server.
General Information Auto Configuration (IPv6 Standard) The UTN server can have an IPv4 address and several IPv6 addresses at the same time. The IPv6 standard is used to automatically assign IP addresses in IPv6 networks. When connected to an IPv6 network, the UTN server will automatically obtain an additional link-local IP address from the IPv6 address range. The UTN server uses the link-local IP address to search for a router.
General Information myUTN Control Center You can manually enter the desired IP address and save it in the UTN server using the myUTN Control Center. • To configure an IPv4 address via the myUTN Control Center, see: Ö 36. • To configure an IPv6 address via the myUTN Control Center, see: Ö 38. ARP/PING The assignment of the IP address to the hardware address can be done via the ARP table. The ARP table is an internal system file in which the assignment is temporarily saved (about 15 min).
Administration Methods 2 Administration Methods You can administer and configure the UTN server in a number of ways. The following chapter gives you an overview of the various administration options. You will get information on when to use these methods and which functions these methods support.

Proceed as follows: 1. Start the InterCon-NetTool. 2. Select the UTN server from the device list.
Network Settings 3.2 How to Configure IPv6 Parameters You can integrate the UTN server into an IPv6 network. What are the Advantages of IPv6? IPv6 (Internet Protocol version 6) is the successor of the more common IPv4. Both protocols are standards for the network layer of the OSI model and regulate the addressing and routing of data packets via a network. The introduction of IPv6 has many benefits: • IPv6 increases the IP address space from 232 (IPv4) to 2128 (IPv6) IP addresses.
Network Settings The URL will only be accepted by browsers that support IPv6. Which Types of IPv6 Addresses are available? There are different types of IPv6 addresses. The prefixes of the IPv6 addresses provide information about the IPv6 address types. • Unicast addresses can be routed globally. These addresses are unique and therefore unambiguous. A packet that is sent to a unicast address will only arrive to the interface that is assigned to this address. Unicast addresses have the prefixes '2' or '3'.
Network Settings Table 3: IPv6 Parameters Parameters Description IPv6 Enables/disables the IPv6 functionality of the UTN server. Automatic configuration Enables/disables the automatic assignment of the IPv6 address for the UTN server. IPv6 address Defines a UTN server IPv6 unicast address assigned manually in the format n:n:n:n:n:n:n:n. Every 'n' represents the hexadecimal value of one of the eight 16 bit elements of the address.
Network Settings ª The settings are saved. Table 4: DNS Parameters Parameters Description DNS Enables/disables DNS. Primary DNS server Defines the IP address of the primary DNS server. Secondary DNS server Defines the IP address of the secondary DNS server. The secondary DNS server is used if the first one is not available. Domain name (suffix) Defines the domain name of an existing DNS server. 3.
Network Settings 1. 2. 3. 4. ª Proceed as follows: Start the myUTN Control Center. Select NETWORK - SNMP. Configure the SNMP parameters; see: Table 5 Ö 42. Click Save & Restart to confirm. The settings are saved. Table 5: SNMP Parameters Parameters Description SNMPv1 Enables/disables SNMPv1. Read-only Enables/disables the write protection for the community.
Network Settings When checking the IP address assigned via ZeroConf (see: ’ZeroConf’ Ö 14) the UTN server sends a query to the network. If the IP address has already been assigned elsewhere in the network, the UTN server will receive a message. The UTN server then sends another query with a different IP address. If the IP address is available, it is saved in the UTN server. The domain name service is used for additional Bonjour features.
Network Settings 3.6 How to Configure POP3 and SMTP (only myUTN-80 and later) You must configure the protocols POP3 and SMTP on the UTN server so that the notification service (Ö 57) and the remote maintenance via email (Ö 31) will work properly. POP3 'POP3' (Post Office Protocol Version 3) is a transfer protocol that a client can use to fetch emails from a mail server. POP3 is required to administer the UTN server via email.
Network Settings Parameters Description POP3 - Server port Defines the port used by the UTN server for receiving emails. The port number 110 is preset. When using SSL/TLS, enter 995 as port number. POP3 - Security Defines the authentication method to be used (APOP / SSL/TLS). When using SSL/TLS, the cipher strength is defined via the encryption level Ö 80. POP3 - Check mail every Defines the time interval (in minutes) for retrieving emails from the POP3 server.
Network Settings Parameters Description SMTP - TLS Enables/disables TLS. The security protocol TLS (Transport Layer Security) serves to encrypt the transmission between the UTN server and the SMTP server. The cipher strength is defined via the encryption level SMTP - Sender name Defines the email address used by the UTN server to send emails. Note: Very often the name of the sender and the user name are identical. SMTP - Login Enables/disables the SMTP authentication for the login.
Network Settings 3.7 How to Configure WLAN (myUTN-54 only) The UTN server model 'myUTN-54' can handle WLAN. This allows you to wirelessly operate the UTN server in the network. What is WLAN? WLAN is a radio technology that allows you to establish wireless connections between network components. The WLAN technology is defined as a standard of the IEEE 802.11 family. The myUTN-54 supports the standards IEEE 802.11b, IEEE 802.11g and IEEE 802.11n.
Network Settings WEP WEP (Wired Equivalent Privacy) is an encryption method according to IEEE 802.11 on the basis of the RC4 encryption algorithm. WEP offers mechanisms for data encryption and authentication. WEP uses a key to encrypt the entire communication. As for encrypted access points, the same WEP key must be used for the access point and the UTN server. Some access points convert WEP keys that are entered as ASCII text into arbitrary hexadecimal values.
Network Settings Using the UTN Server (myUTN-54) in a Wireless Network To operate the UTN server in a wireless network, the WLAN and security settings of the UTN server must match those of the wireless network. In order to configure the UTN server you must first establish a connection to a wired network by means of the network connector RJ-45; see: 'Quick Installation Guide'.
