4POWERING ON THE TA7104/7108
This chapter describes the initial provisioning of the TA7104/7108.
4.1 IP ADDRESS DISCOVERY OR CONFIGURATION
This section describes how to contact the TA7104/7108's management interface to start with unit
configuration.
Note that the TA7104/7108 IPv6 interface is disabled by default.
Once the physical connection is complete and the TA7104/7108 is powered up, you must first find out
the IP address the TA7104/7108 is using. The TA7104/7108's IP address can be set either
dynamically or statically. The default behavior of the TA7104/7108 is to try to obtain a dynamic IP
address through a DHCP server.
Dynamic IPv4 Address Discovery
The default configuration is set so that the unit can be directly plugged into a network and provisioned
with a DHCP server. Mitel strongly recommends to set your DHCP server before installing the unit on
the network. This way, you know the IP address associated with a particular unit.
Caution: If you set a TA7104/7108 with a static eth1-4 IPv4 address in a subnet (for
instance,192.168.200.1) and the eth5 interface receives a dynamic IP address in the same subnet (via
a DHCP server or PPP peer), you will not be able to contact the unit via the WAN. You must be careful
that a dynamic IP address does not overlap a static IP subnet that is already configured. Note that the
current default value of the TA7104/7108 is 192.168.0.10.
See the Software Configuration Guide for more details on how to set an external DHCP server.
Caution: If you are experiencing problems, or if you do not want to use a DHCP server and use a
static IP address instead, perform a Partial Reset procedure, as explained in Partial Reset.
DHCP servers generally allocate a range of IP addresses for use on a network and reserve IP
addresses for specific devices using a unique identifier for each device. The TA7104/7108 unique
identifier is its media access control (MAC) address. You can locate the MAC address as follows:
It is printed on the label located on the bottom side of the unit.
It is stored in the System Information page of the web interface.
If you have not reserved an IP address, you can discover which IP address has been assigned to the
TA7012i by either:
Taking one of the telephones connected to the TA7104/7108 and dialing *#*0 on the keypad.
The current IP address of the TA7104/7108 (static or DHCP) will be stated.
Consulting your DHCP server's logs to find out details on the DHCP lease that was given to the
TA7104/7108.
Using a network packet sniffer (e.g., Wireshark) to examine the DHCP messages exchanged
between the TA7104/7108 and your DHCP server while the TA7104/7108 boots up.
The TA7104/7108 should be already running. If not, power it on by connecting the other end of the
power adaptor to an electrical earthed socket-outlet. The electrical outlet must be installed near
the TA7104/7108 so that it is easily accessible.
Note: If the Power LED is always blinking and never turns on, this means that the TA7104/7108
cannot find either an IPv4 DHCP server or an IPv6 address automatically. Check that you have a
DHCP server properly configured on your network. If you do not have a DHCP server, go to the
section Default Static IPv4 Address Configuration.
You can now access the TA7104/7108 web interface. Refer to the Software Configuration Guide for
more details.

Initial Provisioning Sequence
When starting the TA7104/7108 for the first time, it needs to be configured before it can support calls.
This process is known as provisioning. This sequence assumes that you have installed the
TA7104/7108 hardware as per Hardware Installation.
The TA7104/7108 requests its configuration only on the first restart. You can change the configuration
at will after the initial provisioning and the provisioning system can refresh the TA7104/7108
configuration.
Initial provisioning sequence:
1. When the TA7104/7108 starts, it broadcasts a message requesting DHCP services (if the unit is
configured to start in DHCP mode).
2. The DHCP server responds with a set of IP addresses and network parameters, one of which is
the TA7104/7108 IP address.
The following are some of the network parameters assigned via DHCP:
TA7104/7108 IP address
Subnet Mask
Default Router IP address
DNS IP addresses
Configuration script server IP address and port number (optional)
SIP Servers IP address and port number
The TA7104/7108 request its configuration by using a configuration file.
Default Static IPv4 Address Configuration
If there is no DHCP server in your network, then the IP address has to be configured statically.
To start the TA7104/7108 with a static IP address:
1. With a 10/100 Hub and two 10/100 BaseT Ethernet RJ-45 straight cables, connect both cables to
the Hub; one of them is connected into the WAN connector. The other cable links the computer to
the Hub.
2. Reconfigure the IP address of your computer to 192.168.0.11 and the Subnet Mask to
255.255.255.0.
3. Restart the computer.
4. Power on the TA7104/7108, by connecting the other end of the power cord to an electrical outlet.
The electrical outlet must be installed near the TA7104/7108 so that it is easily accessible.
5. Insert a small, unbent paper clip into the Reset / Default hole located at the rear of the
TA7104/7108. The Power LED will start blinking, and after a few seconds, all the LEDS will start
blinking. Release the paper clip after all the LEDs start blinking and before they all stop blinking
(between 7-11 seconds).
This procedure is called a partial reset. After a partial reset is performed, the TA7104/7108 uses
the default IP address 192.168.0.1/24. Refer to “Partial Reset” for details on the partial reset
procedure.
The corresponding link-local IPv6 address is also available and printed on the sticker under the
TA7104/7108.
You can now access the TA7104/7108 web interface. Refer to the Software Configuration Guide
for more details.
IPv6 Link Local Address Configuration
If there is no DHCPv6 server or IPv6 router in your network, you can use the link local address to
contact the unit. Note that the TA7104/7108 IPv6 interface is disabled by default.

blinking. Release the paper clip after all the LEDs start blinking and before they all stop blinking
(between 7-11 seconds). This procedure is called a partial reset. After a partial reset is performed,
the TA7104/7108 enables its link local IPv6 address. Refer to Partial Reset for details on the
partial reset procedure. The corresponding link-local IPv6 address is also available and printed on
the sticker under the TA7104/7108.
4. Proceed with accessing the TA7104/7108’s web interface by using the unit’s link local address.
The unit’s link local address is printed on a sticker under the unit. The link local address can be
determined by using the following pattern: [fe80::290:f8ff:feXX:XXXX] where XXXXXX are the last
6 digits of the unit’s MAC address. Example: The link local address for the TA7104/7108 with
MAC address 00:90:F8:12:34:56 would be [fe80::290:f8ff:fe12:3456].
Note: On Windows, a scope ID needs to be added to the link local address
([fe80::290:f8ff:fe12:3456%11]). You can find this number by executing the ‘ipconfig’ command in a
command prompt. Note the number at the end of the IPv6 default Gateway for the interface used to
contact the unit. On Linux, the scope identifier may be the link name or the interface number. The
interface number can be determined through the Linux command line.

Verifying the Installation
There are a few ways to verify that the TA7104/7108 is properly connected to the IP network and is
working:
By contacting it with a SNMP browser
By contacting it via the CLI
By contacting it via a web browser
By pinging it
These procedures assume that you know the IP address of the TA7104/7108 you want to verify. If the
TA7104/7108 does not respond, do the following:
Verify that the LAN and WAN cables are securely connected to the TA7104/7108 and to the
network connectors.
Be sure that you did not connect crossover network cables.
Verify the state of the IP network to ensure it is not down (the ETH LED should be ON or blinking).

At Start-Time
You can use the RESET/DEFAULT button at start-time –you power the unit off, and then depress the
button until the LEDs stop blinking and remain ON. This applies the “Factory Reset” procedure (see
Factory Reset). This feature reverts the TA7104/7108 back to its default factory settings.
Partial Reset
The Partial reset provides a way to contact the TA7104/7108 in a known and static state while keeping
most of the configuration unchanged.
Following a partial reset, the TA7104/7108 management interface is set to the Rescue interface. The
default address for this interface is 192.168.0.1/24 and has its corresponding link-local IPv6 available
and printed on the sticker under the TA7104/7108. Any existing network interface that conflicts with
the Rescue interface address is disabled.
You can contact the TA7104/7108 at this address to access its configuration parameters. It is not
advised to access the unit on a regular basis through the Rescue network interface. You should
reconfigure the unit’s network interfaces as soon as possible in order to access it through another
interface. See After a Partial Reset for more details.
In a partial reset, the following services and parameters are also affected:
AAA service: User(s) from profile are restored with their factory password.
SNMP service: Resets the enableSnmpV1, enableSnmpV2, enableSnmpV3 and snmpPort values
to their default values.
WEB service: Resets the serverPort to its default value.
To trigger the Partial Reset:
1. Insert a small, unbent paper clip into the RESET/DEFAULT hole located at the rear of the
TA7104/7108. While pressing the RESET/DEFAULT button, restart the unit. Do not depress
before all the LEDs start blinking (between 7-11 seconds).
2. Release the paper clip.
After a Partial Reset
Following a partial reset, you should:
1. Create or activate network interfaces as described in the Software Configuration Guide, Chapter
Interface Parameters, Section Interfaces Configuration. Do not disable the Rescue interface!

2. Change the TA7104/7108 system management network interface to something other than Rescue
as described in the Software Configuration Guide, Chapter Miscellaneous –Management
Interface, Section Management Interface Configuration. Note that you must be able to contact the
interface you select in order to continue with the following steps.
3. Contact the TA7104/7108 through the new system management network interface.
4. Disable the Rescue network interface as described in the Software Configuration Guide, Chapter
Interface Parameters, Section Interfaces Configuration.
Factory Reset
The Factory reset reverts the TA7104/7108 back to its default factory settings. It deletes the persistent
MIB values of the unit, including:
The firmware pack download configuration files.
The SNMP configuration, including the SNMPv3 passwords and users.
The PPPoE configuration, including the PPP user names and passwords.
The Factory reset creates a new configuration file with the default factory values. It should be
performed with the TA7104/7108 connected to a network with access to a DHCP server. If the unit
cannot find a DHCP server, it sends requests indefinitely.
To trigger the Factory Reset:
1. Power the TA7104/7108 off.
2. Insert a small, unbent paper clip into the Reset / Default hole located at the rear of the
TA7104/7108. While pressing the Reset / Default button, restart the unit. Do not depress before
the LEDs stop blinking and are steadily ON.
3. Release the paper clip. The TA7104/7108 restarts. This procedure resets all variables in the MIB
modules to their default value. When the TA7104/7108 has finished its provisioning sequence, it is
ready to be used with a DHCP-provided IP address and MIB parameters. This procedure can also
be performed at run-time.
Note: The Factory reset alters any persistent configuration data of the TA7104/7108.
