Chapter 2 Installation
IOLAN+ will now automatically download this configuration on reboot. Remember that
whenever you change a setting on the unit, it will be overwritten the next time the unit is
rebooted unless the new configuration is saved.
Domain Name Server (DNS)
IOLAN+ can be configured to take advantage of your network’s Domain Name Server (DNS).
This is done from the server in the Administration Menu by keying in the IP address of your
DNS in the Name server field. Fill in the Domain name field as well.
Reassigning IOLAN+ to a New Network
If you need to attach IOLAN+ to a different network with a new IP address, it is possible to
reset it to factory default condition using the following procedure:
1. Connect your IOLAN+ unit to the new network.
2. Power on the unit, and connect to a CLI using a serial terminal.
3. At the command prompt, type the following:
Local> su
Password>
ADMIN:Local> facreset
Do you really want to do this (y/n) [n] ? y
Performing factory reset ...
The IOLAN+ unit will now reboot and begin sending BOOTP request packet on the new
network.
This procedure is useful for factory defaulting units which cannot be reached via TCP/IP. This
includes reassigning a programmed unit to a network to which the previously assigned IP
address does not belong.
Updating IOLAN+ Firmware
Firmware can be downloaded across the network using tftp protocol if the host machine and
file name are set in the boot host and boot file entries of the server menu. These entries are
checked at start up and if they have been configured, the relevant file will be downloaded.
Note:
tftp must be enabled on the relevant host as it is disabled by default
