I think you can often translate this expression with "installation", but it doesn't quite mean the same thing, and is not appropriate in this case, as shown below:

(This is not quite the same context, as they are refering to nuclear reactors, but here is another term used to translate that expression):

"mise en exploitation start-up, commissioning"
[PDF] jltc.army.mil/jltc/fbis/fnu.pdf

but here are other examples, more appropriate:

"Hardware services include:

Hardware installation
Hardware installation and startup "
http://vcmproapp02.compaq.com/ActiveAnswers/Global/en/soluti...

"Harware Installation and Startup: A full range of hardware configuration, staging, and installation and startup services."
www.compaq.com/services/software/ss_linux.html

" Smart solutions for taking time, worry, and risk out of hardware and software deployment

Save time and hassles with one-stop shopping for all your installation and startup needs. "
www5.compaq.com/services/management/ms_installation.html

And here is another spelling (several more examples on the Net):

"CarePaq Installation and Start-up Services ensure that your system is set up the way it should be. "

Hope this helps.
