CAUTION

NOTE

Download New Firmware

Xmodem Download of Firmware

If you selected a baud rate other than 9600, the message following the successful download will not be displayed correctly. In this case, wait approximately 2 minutes before power cycling the probe to ensure that the new firmware is written to FLASH memory correctly.

If your download was not successful, it is recommended that you repeat the process using 9600 baud so that all error message will be displayed correctly.

After the download process is complete, LanProbe reboots and starts running the new firmware.

If an error occurs during the download process, LanProbe returns to the Main Menu without storing the new firmware to memory.

If you are using an HP workstation and LanProbe takes more than 90 seconds to download new firmware and to restart (boot), verify that the workstation is setup correctly, and restart inetd by entering and running the following commands at the workstation:

ps -ef grep inetd /etc/inetd -k /etc/inetd

If you are experiencing tftp transfer timeouts or read errors, use the following procedure to verify that tftp is configured correctly on your unix workstation.

1.Verify tftpd functionality by copying the firmware file to another directory using the tftp command.

a.cd/tmp

b.tftp 127.0.0.1

c.get ethsnmp.lp

d.quit

2.If the previous step fails, the problem is due to the tftpd configuration on the unix server.
