Downloading via the Ethernet Port
To download new firmware using TFTP, via the Ethernet port, follow these steps:
Be sure to log in via Telnet. If you log in at a serial port, the download sequence will attempt an Xmodem rather than a TFTP download.
1Obtain the correct image file location and name from 3Com Customer Service.
2Telnet into the PathBuilder S330/S310 unit.
3From the System Administration menu, select [7] Download Firmware. The following prompt appears:
This action will erase the flash memory
Do you want to download firmware (Y/N) [N]?
4Enter y and wait for the Ready to download... message.
5From a workstation or PC (typically the same one doing the Telnet), invoke TFTP using the PathBuilder S330/S310 IP address. From TFTP do:
binary
put image.abs
where image.abs is the filename of the image file to download)
The download will complete in about two minutes (over lightly loaded Ethernet). The TFTP should indicate that the file is transferred, and the Telnet screen should display “download complete.”
Downloading via the Serial Port
To download new firmware using the Xmodem protocol, via the serial port, follow these steps:
You must use a terminal emulation program that supports Xmodem protocol.
1Obtain the correct image file location and name from 3Com Customer Service.
2Log into the PathBuilder S330/S310 unit through a serial port.
3From the System Administration menu, select [7] Download Firmware. The following prompt appears:
This action will erase the flash memory
Do you want to download firmware (Y/N) [N]?
4Enter y. The PathBuilder S330/S310 unit assumes that an Xmodem download is to be done and looks for that protocol over the serial port. Once the unit has erased the flash memory, a message on the screen indicates that the unit is ready to accept an Xmodem download.
5On the terminal emulation prompt, select Xmodem protocol and input the file name of the binary file to be downloaded.
The typical download time at 9600 baud is greater than 30 minutes.
