System Configuration is the way a system is set up, it is the
collection of components that make up the system. Configuration
can refer to either hardware or software, or the combination of
both. For instance, a typical configuration for a PC consists of
32MB (megabytes) main memory, a floppy drive, a hard disk, a
modem, a CD-ROM drive, a VGA monitor, and the Windows
Operating System. Many software products require that the
computer has a certain minimum configuration. For example, the
software might require a graphics display monitor and a video
adapter, a particular microprocessor, and a minimum amount of
main memory capacity.
Installing network cables, whether copper or fiber-optic, can be
dangerous. Often, cables must be pulled through ceilings and
walls where there are obstacles or toxic materials. You should
wear clothing such as long pants, a long-sleeved shirt, sturdy
shoes that cover your feet, and gloves to protect you from those
toxic materials. Most importantly, wear safety glasses.
3. SAFETY PRECAUTIONS
WHEN USING A LADDER:
• Read the labels on the ladder, and follow any
safety instructions written on it.
• Never stand on the top rung of the ladder. You
could easily lose your balance and fall.
• Make sure that people in the area know you
will be working there.
• Cordon off the area with caution tape or safety
cones.
• When you are using a ladder that leans up
against a wall, follow the instructions written
on the ladder, and have someone hold the
ladder to help keep it steady.
4. SAFETY RULES WHEN
WORKING WITH CABLES:
• Make sure that the tools you are using are in
good working condition.
• Watch what you are doing, and take your
time. Make sure that you do not cut yourself or
place anyone in danger.
• Always wear safety glasses when cutting,
stripping, or splicing cables of any kind. Tiny
fragments can injure your eyes.
• Wear gloves whenever possible, and dispose
any waste properly.
5. FIBER-OPTIC SAFETY
Chemicals
The solvents and glues used with fiber optics are
dangerous. You should handle them with extreme
care. Read the instructions on the label, and
follow them carefully. Also, read the material
safety data sheet (MSDS) that accompanies the
chemicals to know how to treat someone in case
of emergency.
6. FIBER-OPTIC SAFETY
Tools
When working with any tool, safety should
always be your first priority. Any compromise in
safety could result in serious injury or even
death. The tools used for working with fiber
optics have sharp cutting surfaces that are used
to scribe glass. Other tools pinch cables with high
pressure to fasten connectors to them.
7. FIBER-OPTIC SAFETY
Glass Shards
The process of cutting and trimming the strands
of fiber-optic cables can produce tiny fragments
of glass or plastic that can penetrate your eyes or
skin and cause severe irritation. The fibers can
be extremely difficult to see on your skin because
they are clear and small. When you work with
fiber-optic cabling, the working surface should be
a dark mat so that you can see the tiny glass or
plastic fragments.
8. FIBER-OPTIC SAFETY
Harmful Light
Protect your eyes from the harmful light that may
be in the fiber-optic strands. The light is a color
that humans cannot see. It can damage your
eyes before you can feel it. When you use a
magnifier to inspect fiber-optic cable and
connectors, the light emitted from the fiber could
be directed into your eyes. When working with
fiber, be sure to disconnect the light source. Use
special detectors to help you tell if a fiber is
energized.
