Actually it’s not classified an S8100 since it's running NT. It's most likely a TN795 processor and called an IP600 if it’s the rack-mount box (10 slots with the glove box on the right) or a DefinityOne if it looks like a Prologix cabinet.
And you must remember this acronym specific to this product. DONT = Definity on NT. It's something they should have never done. S8100 term came around with the TN2314 processor running Win2000.
Here’s a little education for you.
The logins are lucent1, lucent2, and lucent3. They correspond to init, inads, and craft. So if you need the lucent3 login, you'll want the craft one.
Now you need to get to the desktop of the server (can I use 'server' term with this product?). Hopefully your customer has a mouse, monitor and keyboard hooked up to the cable that comes off of the TN795 processor. if not, you'll do the crossover cable to the NIC port of the PCMCIA NIC that's sticking out of the front of the TN795 processor and use the Remote Desktop program to get over to the desktop of the box. The desktop login is NTadmin/NTadmin1 (it’s in the documentation). However you get to the desktop, do this next. Take the 128mg memory card out of the TN795 processor and stick it into your laptop's PCMCIA slot. Let your laptop recognize the card, then copy the license file over to the memory card. Remove the card (use the icon in the system tray of your laptop to stop it) and then slide the card back into the IP600/DefOne. You'll now be able to, using the mouse, monitor, and keyboard attached to the IP600/DefOne or using Remote Desktop on your laptop, to copy the license file from the memory card to the correct location, D:/LucentPub/ftproot. Now go to the run command (under the Start menu) of the IP600/DefOne and type 'bash'. In the bash window type 'cd //D/LucentPub/ftproot'. Type 'ls' to make sure the new license file is there. Now type loadlicense 'license-name.lic'. Let that execute successfully (you'll see it in the bash window). Now type 'reboot nice' in the bash window. It will take 5-7 minutes to reboot and MultiVantage to start up, then another 5-7 minutes for the IA770 Audix software to come up. There’s actually a daughter card on the processor that's the actual IA770. Nowadays it's just software. So after the Microsoft OS loads and you can get to the desktop, do the Start->Run->bash thing again. Type 'd1stat' to watch the processes come up. Test all the things you should test, outbound calling, inbound calling, audix, etc. you're all done.
Any other questions about IP600/DefOne/S8100, hit me up. I was the only Lucent tech that enjoyed working on them in New England. I guess I was a glutton for punishment.
