Tsunami QB-8100 Series (100 Mbps/5 Mbps Models) Installation and Management Guide 192
8.4.5 Telnet CLI Does Not Work
1. Make sure you have the proper IP Address. Enter your device IP address in the Telnet connection dialog, from a DOS
prompt, type: C:\> telnet <Device IP Address>
2. Use the CLI over the serial port to check the IP Access Table, which may be restricting access to Telnet and HTTP.
8.4.6 TFTP Server Does Not Work
With TFTP, you can transfer files to and from the QB-8100 device. Also see TFTP Server Setup. If a TFTP server is not
properly configured and running, you cannot upload and download files.
The TFTP server:
Can be situated either local or remote
Must have a valid IP address
Must be set for send and receive without time-out
Must be running only during file upload and download
If the TFTP server does not upload or download files, it could mean:
The TFTP server is not running
The IP address of the TFTP server is invalid
The upload or download directory is not correctly set
The file name is not correct
8.4.7 Setting IP Address using Serial Port
Use the following procedure to set an IP address over the serial port using the CLI. The network administrator typically
provides the device IP address.
8.4.7.1 Hardware and Software Requirements
Standard cross-over serial data (RS-232) cable (not included with shipment).
ASCII Terminal software, such as HyperTerminal.
8.4.7.2 Attaching the Serial Port Cable
1. Connect one end of the serial cable to the unit and the other end to a serial port on your computer.
2. Power on the computer and unit, if necessary.
8.4.7.3 Initializing the IP Address using CLI
After installing the serial port, you may use the CLI to communicate with the device. CLI supports most generic terminal
emulation programs, such as HyperTerminal (which is included with the Windows operating systems). In addition, many web
sites offer shareware or commercial terminal programs you can download. Once the IP address has been assigned, you can
use the HTTP interface or the CLI over Telnet to complete the configuration.
Follow these steps to assign the QB-8100 unit an IP address:
1. Open your terminal emulation program (like HyperTerminal) and set the following connection properties:
Com Port: <COM1, COM2, etc., depending on your computer>
Baud rate: 115200
Data Bits: 8
Stop bits: 1
Flow Control: None
