E-28 Erasing IR-IP Software
E.13 Erasing User’s Configuration
The user-defined configuration parameters are stored in the IP router card
flash memory. After the user-defined configuration parameters are erased,
the IP router card automatically loads the factory-default parameters .
You may want to erase the current configuration parameters:
1. Before IR-IP is prepared for operation in a new application.
2. When you cannot configure IR-IP because its current LAN-interface IP
address and/or the Telnet password, are not known.
To erase the user’s configuration:
1. Turn HCD-E1 off.
2. Set all the four sections of the IR-IP DIP switch to ON.
3. Turn HCD-E1 on and monitor the ERR indicator: it must turn on and
light steadily.
4. While the ERR indicator is lit (within 15 seconds), set sections 1 and 2
of the DIP switch to OFF.
The IP router configuration is erased.
Note
If you do not set sections 1 and 2 to OFF within 15 seconds of power-up, the
IP router card ignores the setting of all the four sections to ON and starts
normal operation. In this case, it is recommended to turn HCD-E1 off and
then back on.
To abort the whole operation, turn HCD-E1 off, return all the four-switch
section to the desired positions, and then turn HCD-E1 on again.
5. Turn HCD-E1 off, and the return all the four sections of the DIP switch
to the desired positions.
E.14 Erasing IR-IP Software
You may erase the IR-IP application software, without erasing the
user-defined parameters.
After the application software is erased, IR-IP starts its TFTP server
application, and waits for the downloading of software by a TFTP client
connected to its LAN interface. The procedure to be used to download the
application software in this case is also described below.
You may want to erase the application software if the downloading of new
software using the Device Control menu (see Figure E-16) fails, and the IP
router card does not function properly.
