•
Using a network packet sniffer (e.g., Wireshark) to examine the DHCP messages
exchanged between the TA7102i and your DHCP server while the TA7102i boots up.
•
To start the TA7102i with a dynamic IP address:
1. If you need to discover the IP address of the TA7102i, install and start your network packet
sniffer.
2. Power on the TA7102i by connecting the other end of the power cord to an electrical outlet.
The electrical outlet must be installed near the TA7102i so that it is easily accessible.
Note: If the Power LED is always blinking and never turns on, this means that the TA7102i
cannot find either an IPv4 DHCP server or an IPv6 address automatically. Check that you have
a DHCP server properly configured on your network.
You can now access the TA7102i web interface. Refer to the Software Configuration Guide for
more details.
Initial Provisioning Sequence
When starting the TA7102i 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
TA7102i hardware as per Hardware Installation.
The TA7102i 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
TA7102i configuration.
•
Initial provisioning sequence:
1. When the TA7102i 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 TA7102i IP address.
The following are some of the network parameters assigned via DHCP:
•
TA7102i 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 TA7102i request its configuration by using a configuration file.
