INSTALLING THE
. . . . . . . . .
DGy FIRMWARE
After the new firmware has been transferred to the DGy 201, the final
step is to install the firmware into DGy 201 non volatile memory.
Installation of the DGy 201 firmware requires the ufw command to be
issued from a command line interface. You can use either the serial (RS-
232) port or open a Telnet session on the Ethernet (10/100 BASE-T) port
to complete this final step.
1) Connect to the DGy 201 by either the serial port using a serial
emulator or the Ethernet port as a telnet session.
2) Verify that you have established communication to the
command line interface by typing either help at the command
line prompt. If the connection is set up correctly the DGy 201
should respond with a list of commands.
3) Type the command ufw and press ENTER.
4) The DGy 201 will prompt you with a warning message:
“This command will replace the current firmware with the
firmware you just downloaded and restart the system. Do you
want to proceed (y/n) ?”
Type ‘ y to proceed or “n” to terminate the process.
5) When the installation is complete the DGy 201 will automatically
reboot. This is indicated by the front panel LED indicators being
turned on simultaneously. Wait fifteen seconds for the boot
process to complete before moving on to the next step.
6) Reconnect the serial emulator or start a new Telnet session with
DGy 201 and type “ver”. DGy 201 should respond with the new
firmware version number. The firmware upgrade process is now
complete.
Note Communications with the unit will be lost during the
installation process. This is normal and does not
indicate that there is a problem with the installation
process. This process may take several minutes.
Do NOT turn the power off during this time.
