Description
2.3 Rear Panel Connections
The figure shows the rear panel connections of GRT-101/GRT-401/GRT-402.
The STU-R is a standalone and can able to place in desktop. All the external
wiring shall be located at the rear panel. The LAN port is a 10 Base-T /
100Base-TX auto-sensing and half/full duplex Ethernet interface and complied
with IEEE 802.3 / 802.3u respectively. The console (RS-232C) interface for
configuration is menu-driven operation and can also be configured through
Ethernet interface by Telnet or Web-based operation.

Note: GRT-401/GRT-402 support Auto-MDI (media dependence interface) that
auto-detect MDI or MDI-cross with link partner, a standard straight wire UTP
cable (EIA568) can be deployed to connect to a PC or Ethernet devices like
hub/switches. GRT-101 supports MDI interface only.
Step 1: Connect the power adapter to the port labeled DC-IN on the rear
panel of the product.
Step 2: Connect the Ethernet cable.
If GRT-101 is directly connected to PC, the Ethernet cable has to be
used cross over one (refer to figure 2-6). If the product is connected
to hub or switch, be sure that the hub or switch supporting
auto-MDI/MDI-X or not. If yes, both crossover and non-crossover
Ethernet cable are suitable. If not, only non-crossover Ethernet cable
could be used (refer to figure 2-7). Since GRT-401 and GRT-402’s
LAN port supports auto-MDI/MDI-X, both crossover and
non-crossover Ethernet cable are suitable.
Step 3: Connect the phone cable to the product. Connect the other side of
phone cable to wall jack.
Step 4: Connect male end of RS-232 cable to the product and female end to
any free COM port in PC.
Step 5: Connect the power adapter by plugging power supply.
This chapter provides information about configuring
GRT-101/GRT-401/GRT-402.
Note: After you have completed all necessary setting for GRT-101/GRT-401/GRT-402, make sure to write the new
configuration to NVRAM by “write” command and reboot the system, or all of your changes will not take effect.
3.2 Logon Procedure
There are three methods to logon to GRT-101/GRT-401/GRT-402: serial
console, Telnet, and web interface. For the first time configuration, perhaps
only the serial console mode could be used because applications requiring
Internet protocol (IP) communication, such as Telnet and web interface, are not
available unless a management IP is configured properly for your local
networking environment.
After connecting all the necessary cables described in Chapter 2 Installation,
power on GRT-101/GRT-401/GRT-402 and select one of the following
procedures to access GRT-101/GRT-401/GRT-402.
Note: It is recommended that only one configuration application is used to setup GRT-101/GRT-401/GRT-402 at any
given time, that is, Telnet, serial console and the web management interfaces should not be used simultaneously.
3.2.1 Serial console
Check the connectivity of the RS-232 cable from your computer to the serial
port of GRT-101/GRT-401/GRT-402. Start your terminal access program with
VT100 terminal emulation. Configure the serial link with baudrate of 9600, 8
data bits, no parity check, 1 stop bit, and no flow-control, and press the
SPACE key until the login screen appears. When you see the login screen,
you can logon to GRT-101/GRT-401/GRT-402.
User: admin
Password: *****
Note: If you have not set any user profile for GRT-101/GRT-401/GRT-402, enter the factory default user “admin”.
When the system prompts you for a password, type “admin” to enter GRT-101/GRT-401/GRT-402.
After you logon to GRT-101/GRT-401/GRT-402 and before proceeding any
further, check the software version of GRT-101/GRT-401/GRT-402 by the
command:
admin> show system
If firmware file is downloaded from our local distributor or FTP server, please
refer to TFTP command in the section 3.18 Software Upgrade for more
information on how to update GRT-101/GRT-401/GRT-402 firmware.
3.2.2 Telnet
Make sure the correct Ethernet cable is used for connecting the LAN port of
your computer to GRT-101/GRT-401/GRT-402. The LAN LNK indicator on the
front panel shall light if a correct cable is used. Starting your Telnet client with
VT100 terminal emulation and connecting to the management IP of
GRT-101/GRT-401/GRT-402, wait for the login screen appears. When you see
the login screen, you can logon to GRT-101/GRT-401/GRT-402.
User: admin
Password: *****
Note: The factory default management IP and subnet mask are of 192.168.0.1 and 255.255.255.0, respectively. To
change these setting, see section 3.10.1 Bridge management and 3.11.1 LAN setting for routing mode operation. If
you have not set any user profile for GRT-101/GRT-401/GRT-402, enter the factory default user “admin”. When the
system prompts you for a password, type “admin” to enter GRT-101/GRT-401/GRT-402. For more security issues for
remote management interfaces such as Telnet and web interface, see section 3.15 Management Security.
3.2.3 Web browser
Make sure the correct Ethernet cable is used for connecting the LAN port of
your computer to GRT-101/GRT-401/GRT-402. The LAN LNK indicator on the
front panel shall light if a correct cable is used. Starting your web browser and
connecting to the management IP of GRT-101/GRT-401/GRT-402, wait for the
login screen appears. When you see the login screen, you can logon to
GRT-101/GRT-401/GRT-402.
Note: The factory default management IP and subnet mask are 192.168.0.1 and 255.255.255.0 respectively. To
change these setting, see section 3.10.1 Bridge management and 3.11.1 LAN setting. If you have not change
password setting for web interface, enter the factory default user “root”. When GRT prompts you for a password, type
“root”. More security issues for remote management interfaces, please refer to section 3.15 Management Security.
