3. Open a telnet session to your IP40 using the above IP address and user name/password
information
4. Upload the firmware file to the device using FTP or TFTP. You will be prompted for
confirming firmware upgrade once the upload is completed
5. Upgrade your device's firmware by clicking Yes. IP40 will verify whether the firmware file
you uploaded is valid before upgrading.

Booting in to Failsafe Mode

The IP40 goes in to the failsafe mode when the main kernel gets corrupted. If the main kernel
gets corrupted, the IP40 loads a failsafe kernel to the RAM. For the device to function properly,
it must be upgraded with a new firmware.
You can upgrade the firmware using OOB or using Console and LAN.
If the device is booted in failsafe mode, you will get the following login prompt:
Welcome to IP40 (failsafe)
login:
The user name and password are "admin" and "password" respectively.

Special Deployment Mode in the Nokia IP40

Holding the reset button and plugging the power to IP40 , boots the device in special deployment
mode. In this mode, firewall allows access to SSH/HTTPS from OOB for half an hour. You can
set the first-time password and configure the device remotely using OOB. However after half an
hour, firewall will start filtering the traffic as usual. This might cause disconnection of existing
SSH/HTTPS sessions over the OOB interface.
