Figure 5-9 Firmware upgrade
To use either a remote or serial console to upgrade your firmware , the TELENT/SSH or terminal
emulation program must support Zmodem transfer protocol. The previous settings will be retained
after the firmware upgrade.
To upgrade firmware via a remote console:
1. Obtain the latest firmware.
2. Connect the terminal emulation program using either TELENT/SSH or a serial console
port. (TELNET or SSH is recommended since the process of firmware upgrade by serial
console requires extremely long time.)
Select from the firmware upgrade menu as shown in Figure 5-10.오류 ! 참조 원본을 찾을
