5. Hardware Installation
1.Connect the SDSL cable, (item 1) indicated in Figure 3, to
the LINE port of RJ-11 socket.
2.Use a RJ-45 cable, (item 2) indicated in Figure 3, to connect
the SDTU-01/ET10 to the LAN or a PC with Ethernet adapter
installed.
Note: Be sure to use RJ-45 cross-over cable when
connecting to a hub.
3.Plug in the AC adapter to an AC power socket, then connect
the DC jack, (item 3) indicated in Figure 3, the DC inlet of the
SDTU-01/ET10.
4.Use a 9-pin RS-232 cable (item 4) indicated in Figure 3, to
connect the Console Port to a serial port of a terminal such
as PC with data terminal emulation software (Hyper Terminal)
installed, in order to perform local management.

6. Management
SDTU-01/ET10 supports simple, flexible and easy-to-operate
methods for management purposes. The SDTU-01/ET10 can be
managed via the following paths, refer to Appendix B for
detailed information.
üConsole port – use the RS-232 cable for connecting SDTU-
01/ET10 to a console terminal or a PC running terminal
emulation program, such as Hyper Terminal, see Appendix A for
proper console setup.
üLocal Ethernet Port – connect the Ethernet port to your local
area network or to a PC directly, “Telnet” SDTU-01/ET10 from any
workstation on the LAN.
üSDSL port from remote site – while SDSL connection is in
service, you may remotely “Telnet” SDTU-01/ET10 from a
workstation networking to the CO equipment.
Note: As operating SDSL modem requires technical know-how and
experience, it is recommended that management of the SDTU-
01/ET10 be performed by qualified technical staff only.

8. Software Upgrade
You may easily upgrade the SDTU-01/ET10's embedded
software by obtaining the compressed upgrade kit, ZIP file, from
the service provider then following the steps:
üExtract the ZIP file
üConnect SDTU-01/ET10 via the local Ethernet port or remote
SDSL link, make sure the SDTU-01/ET10 Ethernet IP address is
set and your terminal is properly configured so you can
successfully “ping” SDTU-01/ET10.
üUnder a DOS prompt, execute the command line “xupgrade
<IP address of SDTU-01/ET10>”, for instance “xupgrade
192.168.2.1”.
üThis upgrade process may take as long as 60 seconds.
üThen reboot SDTU-01/ET10 with new software.
NOTE: Strictly maintain stable power to SDTU-01/ET10 while
upgrading software. If 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 repair.
