5.4 Resetting the Device to its Standard Configuration
For local maintenance tasks, if an unknown state of the CAN-Ethernet
Gateway or a faulty configuration is detected, then it is necessary to be
able to communicate with the CAN-Ethernet Gateway at a fixed IP
address. The IP address 192.168.10.111 is used for the standard
configuration.
In order to set the device to its default IP address 192.168.10.111, the
switch "DEFT" must be set to ON. Now perform a power-on reset by
briefly interrupting the supply voltage.
Note: Saved configurations (/save/rc) are not deleted.
As an alternative, access over the RS-232 interface is possible,
whereby access to the CAN-Ethernet Gateway occurs independently
of the IP address.
5.5 Assigning Passwords
There is also the possibility of creating a password for access via
Telnet and RS-232. To do this the file
passwd located in the /save
directory is used. The contents of this file corresponds to the
password. The file is created using the commands
write and sync.
Example:
/ >cd save change to the /save directory
/save >write passwd creates the file passwd
xyz0815 sets the password, finish the entry with
Ctrl+D
/save >sync saves the password in EEPROM
/save >reset software reset
Bye. Enter password: prompts to enter the password when
starting a new session over Telnet or
RS-232
Entry of an incorrect password will be answered with Access
denied.
