Cannot find a manual on this product, any start point to learn to use this load balancer will be appreciated since Nortel does not support this product anymore i couldn't find any information on their site.
The software running on the Nortel Alteon load balancers is called WebOS. The AD3/180E load balancers run version 10.
The guide you want is called WebOS 10 Application Guide. Unfortunately Nortel's site has a annoying system to prevent direct linking to documents, but the first two links from this search will give you the guide and the command reference
