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.
1 Obtain the correct image file location and name from 3Com Customer Service.
2 Telnet into the PathBuilder S330/S310 unit.
3 From 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]?
4 Enter y and wait for the Ready to download... message.
5 From 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.
1 Obtain the correct image file location and name from 3Com Customer Service.
2 Log into the PathBuilder S330/S310 unit through a serial port.
3 From 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]?
4 Enter 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.
5 On 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.
