To use either a Telnet or serial console to upgrade your firmware, the Telnet or terminal emulation
program must support Zmodem transfer protocol.
To upgrade firmware via Telnet or serial console:
1. Obtain the latest firmware.
2. Make connection using a terminal emulation program. (Telnet is recommended since the
process of firmware upgrade by serial console may be slower.)
3. Select from the firmware upgrade menu as shown in Figure 0-10.
4. Follow the online directions and transfer the firmware binary file using the Zmodem
protocol as shown in Figure 0-11.
5. Once the upgrade has been completed, the system will reboot to apply the changes
6. If the firmware upgrade fails, the UPSLink will display error messages as shown in Figure
0-12. It maintains the current firmware version.
