IBM 704 - Manual (Page 35)

Before You Begin
If you have not already done so, unpack your server. If you are not
installing any optional hardware now, connect the cables and power
cord. Follow the instructions on the Setup sheet that comes with
your server. After you complete these tasks, return here for further
instructions.
Make sure you have an adequate number of properly grounded
electrical outlets for your server, monitor, and any other options
that you intend to install.
Place your server in a location that is dry. Rain or spilled
liquids might damage your server.
Leave about 127 mm (5 in.) of space around the front and rear
of your server to allow the server's cooling system to work
properly.
Have a supply of 1 MB and 2 MB, 3.5-inch diskettes available.
You will need these diskettes later, when you install your
operating system and backup your configuration and all
important data.
