Give the PC a fixed IP address 192.168.42.111
Open Manager and make sure the tftp service is enabled under preferences
In manager open the tftp log viewer
Connect the NIC of the PC to LAN1 of the IPO
connect the IPO with a serial cable to the PC
Open Putty or any other comm.software and open a session on the Com port of the PC 34800,8, N, 1
Keep focus on Putty and boot the IPO while repeatingly pressing escape until you get a message with bootloader bla bla
type AT-X ( capitals! )
it will respond with "erasing image......."
Wait on a reboot and check in the Manager tftp log viewer if the unit tries to load a IP4xxx.bin file.
You'l see the ipadress used, the MAC addres and the file name
If the unit cannot download the file then add a BootP entry in Manager with the MAC addess, IP address and file name as seen in the tftp log
Now it should grab the firmware
if the download aborts at 70% then first load the intermediate version 3.2.999 if it is a 406V2 or Small office before loading the definitive 3.2 version
( had to do it today myself )
By the way why not upgrade to 4.2 for SOE or 5 for 406v2/412 ? These versions are a lot better as 3.2
If it ain't dutch it ain't much
