download a new AP Image. This procedure may be required when the password is
forgotten or the current AP Image is missing or corrupted.
In this procedure, use the Bootloader CLI over the serial port to set the IP Address and
download a new AP Image.
Download procedure
1. To download the MB Image, you will need an Ethernet connection to the computer on
which the TFTP server resides. This can be any computer on the LAN, or connected to
the MB8000’s “LAN” port with a “crossover” Ethernet cable.
2. Then, connect the MB8000 to the computer with a standard serial cable and use a
terminal client, such as HyperTerminal.
3. Before starting, you need to know the MB8000 IP Address, Subnet Mask,the TFTP
Server IP Address, and the AP Image file name.
4. Start TFTP Server, and ensure the new MB Image file is in the TFTP directory.
5. Open your terminal emulator, and set the following connection properties, then connect.
_ Com Port: <COM1, COM2, etc., depending on your computer>
_ Baud rate: 9600
_ Data Bits: 8
_ Stop bits: 1
_ Flow Control: None
_ Parity: None
6. Enable the “ASCII Setup” settings by selecting “Send line ends with line feeds”. Result:
HyperTerminal sends a line return at the end of each line of code.
7. After finishing this preparation, make the MB power up.
8. Press the RESET button.
9. Press and hold the RELOAD button for about 30 seconds until the POWER LED turns
amber. Result: The MB8000 deletes the current MB Image and Configuration files. The
Bootloader CLI becomes active, like this: [Device name]>
10. From the HyperTerminal, enter CLI Commands to set the IP Address and download
an AP Image.
Enter only the following statements.
[Device name]> set ipaddr <MB IP Address>
[Device name]> set ipsubmask <Subnet Mask>
[Device name]> set tftpipaddr <TFTP Server IP Address>
[Device name]> set tftpfilename <AP Image File Name>
[Device name]> reboot
Result: The MB8000 will reboot and then download the image file. Observe the TFTP
display and you should see downloading activity begin after a few seconds.
