Upgrade/Transfer Method
The two methods for upgrading are TFTP and XMODEM.
1. TFTP requires a TFTP server running somewhere on the net-
work. The Router Option Module starts a TFTP client function
which gets the upgrade code from the TFTP server.
2. Selecting XMODEM will load the upgrade code through the
maintenance port using any PC terminal emulator with XMO-
DEM capability.
Upgrade/TFTP Host
This is required when the transfer method is TFTP. It is the IP ad-
dress or domain name (if DNS is configured) of the TFTP server.
Upgrade/Filename
This is required when the transfer method is TFTP. It is the case-sen-
sitive filename which is the upgrade code.
Upgrade/Status
This appears when TFTP is used. It displays the status of the trans-
fer as it happens. Any error or success message will be displayed
here.
Upgrade/Start Transfer
This activator is used when the configurable items in this menu are
complete.
Once started, the Router Option Module will prompt for erasing the flash.
When the flash is erased and the upgrade transfer fails, do not turn off the
unit. Retry the transfer until successful. Otherwise, if power is removed
before upgrade has finished, the upgrade will have to occur from the
maintenance port using XMODEM. If this happens, set a PC terminal
emulation program to 9600 baud and attach to the Router Option
Module's maintenance port. Press Return to display a simple terminal
menu for upgrading. This menu appears when the flash code has been
erased or is corrupt. The menu will also appear if you power up and hold
down the SELECT key for at least five seconds.
