The Report Firmware Version screen displays the following information about the
management processor active firmware (the upgradeable firmware currently being
used by the MCPU):
Version — The released firmware version number. This is the version number that
is displayed on the login screen.
Origins — The original engineering build number for the release.
If the Version and Origins release numbers are the same, then the release is not an
official release but rather a Beta test version.
Who — The user login ID for this software build.
Date — The date and time that the build was made.
Company Name — 3Com Corporation (or OEM partner if desired)
Product Name — The PathBuilder product for which this image was built:
PathBuilder S700, PathBuilder S600, PathBuilder S330, or PathBuilder S310.
In addition to the management processor firmware information listed above, the
Report Firmware Version screen also lists the Boot Firmware Release—the version
number of the boot firmware containing the bootstrap code used to bring up the
operation firmware.)
The PathBuilder S330/S310 module retains the operation firmware in a flash
memory bank located in the motherboard. On power-up or reset, the code image
is copied from the flash memory to the main memory.
The flash memory retains a copy of the operation firmware and can be upgraded
using TFTP or the Xmodem protocol. TFTP is used if you are attached over the
Ethernet interface (standard 10BASE-T or optional 10/100BASE-T) through a
Telnet session. Xmodem is used if you are attached to serial port 1 on a VT100
terminal.
We recommend that you avoid using the serial interfaces unless the Ethernet
interface is unavailable, as a download could take 30 minutes at 9600 baud using
the serial interfaces.
When downloading, the flash memory is overwritten with the new code. Once the
firmware is successfully downloaded, a system reset brings up the new code.
The following instructions pertain to UNIX environments. You can also download
firmware from a PC: from a TFTP application, configure for binary mode, specify
the location of the image files, and use the PUT command.
Downloading Firmware Using TFTP via an Ethernet Port
To download new firmware using TFTP, via an Ethernet port:
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 switch.
