One easy way if you have the options switched on is via Putty, but first copy them in to an ibay via Windows Explorer. That way you can get files moved from a windows machine very easy. Then use Putty to get in via the IP address and SSH, change to the ibay folder and then run the rpm -uvh commands.
In putting your files in to a directory, I find that the easy way is to install server manager installer which means you can actually do any install from the web pages. To do this you need to install the following .rpm.
devinfo-mitel-update-system-0.0.1-14.noarch.rpm
Once you get this installed its so easy..... Just pop in to the server manager and away you go
