Installing System Software using TFTP 49
Installing System
Software using
TFTP
To download the Layer 3 Module software using TFTP, follow the
procedures in this section.
You can load the system software into flash memory while the Layer 3
Module is operating. You do not need to shut down the system.
Before you begin this procedure, make sure that the TFTP server software
is running on the device from which you will be installing the software.
Loading software into flash memory takes approximately 5 minutes to
complete, depending on your network load.
To install the system software using TFTP:
1 Enter the following at the top-level menu:
system softwareUpgrade
The following prompt is displayed:
Host IP address [172.16.200.14]:
Enter the IP address of the host machine (such as a Sun workstation or
PC) from which you are installing the software.
Install file name {?}:
2 To display the filename conventions that you can use, enter
?
3 Enter the complete path and filename.
Some TFTP servers do not accept the full path. If that is the case for your
server, enter only the filename of the image. See your server
documentation for more information.
CAUTION: If the flash installation stops (that is, if you see no activity for
more than 2 minutes), wait for the TFTP session to time out. Do not
reboot the system. When the session has timed out, follow the
installation procedure again.
After the software has been loaded successfully, the following message
appears:
Software upgrade completed
The Layer 3 Module restarts, running the new software after a few
seconds delay.
