14 Upgrading Firmware and Managing Configurations

ROS™ provides the following features for management of system firmware and configuration:

•Upgrading firmware using the XModem protocol and Trivial File Transfer Protocol (TFTP)

•Capturing and restoring the device configuration using XModem and TFTP

•Using SQL commands to view/change configuration

14.1Upgrading Firmware

You may be required to upgrade the device firmware in order to take advantage of new features or bug fixes.

Your firmware has two components; the ROS™ boot loader binary and the ROS™ main application binary. In normal practice only the main application will have to be upgraded. The newest version of the ROS™ main application firmware is available from the RuggedCom Web site. The firmware file name is of the form ROS-CF52_Main_v3-x-y.bin.

You may upgrade using either an XModem or TFTP protocol utility. XModem is used to upgrade from the RS232 port or through a Telnet session.

TFTP transfers may be performed in one of two ways. A TFTP client upon a Unix/Dos workstation can be used to contact the ROS™ TFTP server. This method is very convenient, but will not provide control over who is allowed to upgrade the device software. Alternatively, a TFTP client can be used via the RuggedCom device CLI shell to contact a Unix/Dos host supporting a TFTP server. You must set up a TFTP server on your network, but only admin level users can then perform upgrades.

Note: Security during file transfer by XModem and TFTP is established in the following ways. Transfers from the XModem and TFTP clients are determined by the access level of the user. Downloads may only be performed by administrators while uploads may be performed by operators and administrators. TFTP transfers to devices’ TFTP Server are controlled by TFTP Server parameter under IP Services Configuration Menu.

14.1.1 Upgrading Firmware using XModem

Connect to the device, either through the RS232 port or through a Telnet connection. Press <CTRL S> to enter the shell. Enter the command “xmodem receive main.bin<CR>”. Open the XModem utility in your terminal package. If possible select XModem 1K protocol otherwise select the XModem protocol.
