Import via CSV file

Hi,

I am doing investigation on Opmanager. Il will have more than 100 Servers to discover with printers, routers and desktops. Each of the servers are in their own subnet. Each subnet has one or more printers and one router.

I am trying to figure the format of the csv file : ( I use 3 columns because I saw there is only 3 fields documented with csv in the discovery section)

When I try to import servers, they are categorized as desktops
(Csv format : <Ip address>,<hostname>,Windows 2003)

I do not find which format I need to use to import printers and routers. If I use (<ipaddress>,<printer manufacturer>,printer), none of my printers are discovered.

What do I do wrong and what is the exact format and fields for this csv file ?

Thanks
