Miscellaneous Requirements
The following paragraphs contain information not directly related to the computer system’s
installation process, but each category should be considered in your planning. Your Hewlett-Packard
Sales Representative can help you determine what supplies you will require and the CE can help you
with decisions concerning storage, record protection, and telephone support.
Computer Supplies
Ask your Hewlett-Packard Sales Representative for a catalog of available supplies such as printer
paper, printer ribbon, ink cartridges, plotter paper, tape cartridges, etc.
Media Storage
You should make provisions for storing disc packs, tape cartridges, magnetic tape, and flexible discs in
or near the area where the work is to be performed. The magnetic media storage environment should
be similar to that of the computer; clean and dust free with no exposure to extremes of heat or cold.
Extreme humidity or temperature differences between the working and storage areas can alter the size
of the media when it is moved from one area to the next. This rapid change can result in warping; the
most common media related computer system problem.
If your working and storage areas cannot be kept at the same humidity and temperature, allow ample
time (usually one hour or longer) for the media to achieve a moisture and temperature balance before
using. The maximum rate of temperature change for the media must not exceed 36 degrees Fahrenheit
(20 degrees Celsius) per hour.
Data on magnetic media can be erased by magnetic fields. These magnetic fields are found in power
generating equipment such as motors, alternators, transformers, and data processing equipment (disc
drives). Do not place disc cartridges, tape cartridges, or flexible discs on top of disc drives or power
generating devices.
