V. Hardware Installation
1. Connect one end of the ADSL cable to the WAN port of
X8121r and the other end to the ADSL wall outlet. (X8121r
uses RJ-11 cable and X8121r-B uses RJ-45 cable)
2. Use a RJ-45 cable to connect one end to the Ethernet port of
X8121r, and the other end to the LAN or a PC with an
Ethernet adapter installed.
3. Plug in the AC adapter to the AC power socket, and then
connect the DC jack to the PWR inlet of X8121r.
Note: Be sure to use a RJ-45 crossover cable while connecting to a hub.

VI. Management
X8121r supports simple, flexible, and easy-to-operate methods for
management purposes. X8121r can be managed via the following
paths:
Local Ethernet Port (Telnet) –connect the Ethernet port
to your local area network or directly to a PC. “Telnet”
X8121r from any workstation in the LAN. The default local
Ethernet IP address is “192.168.1.1”.
Local Ethernet Port (Web Browser) –connect the
Ethernet port to your local area network or directly to a PC.
Launch your web browser and enter default local Ethernet
IP address “192.168.1.1” into the address bar.
ADSL Port from Remote Site –while the ADSL
connection is in service, you may remotely “Telnet” X8121r
from a workstation connected to the CO equipment.
Note: As operating an ADSL device requires technical know-how and
experience. It is recommended that only qualified technical staffs
manage X8121r. Therefore, a password authentication is required when
you enter the web interface. To obtain the password, see the Default
Values section.

VIII. Software Upgrade
You may easily upgrade X8121r embedded software by
obtaining the compressed upgrade kit from the service provider then
following the steps:
Extract the ZIP file for updated firmware.
Connect X8121r via the local Ethernet port or remote
ADSL link. Make sure that X8121r Ethernet IP address
and your terminal are properly configured, then you can
successfully “ping” X8121r. The default local IP address is
192.168.1.1.
Under DOS prompt, execute the FTP command “open <IP
address of X8121r>”, then input user name and
password.
Execute upload command “put tepatch.bin“.
This upgrading process may last as long as 60 seconds.
Then reboot to the default values of X8121r with new
software.
Note 1: X8121r software may also be upgraded through the web
interface. See Chapter 2: G. Admin, 3. Image Upgrade
Note 2: Strictly maintain stable power to X8121r while upgrading its
software. If the power fails during the upgrading process, contents in
the memory could be destroyed, and the system may hang. In such a
case, you must call the dealer or system integrator for repairs.

You can configure a bridge or a router, as you feel appropriate. In the
section below, each configuration item is described in detail.
II. Preparation
1) Please refer the hardware installation procedure to install
modem.
2) You should configure the PC to the same IP subnet as the
modem.
For example: The modem: 192.168.1.1
Your PC: 192.168.1.x
3) Let your PC access the modem, and make sure that the
PING function is working properly. The default IP address
