2) Black Box installs dust caps to ensure factory-clean optical devices. These protective
caps should not be removed until the moment of connecting the fiber cable to the
device. Assure that the fiber is properly terminated, polished and free of any dust or
dirt and that the location is as free from dust and dirt as possible.
3) Store spare caps in a dust free environment such as a sealed plastic bag or box so
that when reinstalled they do not introduce any contamination to the optics.
4) Should it be necessary to disconnect the fiber device, reinstall the protective dust
caps.
5) If you suspect that the optics have been contaminated, alternate between blasting
with clean dry compressed air and flushing with methanol to remove particles of
dirt.

Electrostatic discharge (ESD) can cause damage to your add-in modules. Always observe the
following precautions when installing or handling an add-in module or any board assembly
.
1) Do not remove unit from its protective packaging until you’re ready to install it.
2) Wear an ESD wrist grounding strap before handling any module or component. If
you do not have a wrist strap, maintain grounded contact with the system unit
throughout any procedure requiring ESD protection.
WARNING!
Integrated circuits and fiber optic components are extremely suscepti-
ble to electrostatic discharge damage. Do
not handle these components directly unless you are a qualified service technician
and use tools and techniques that conform to accepted industry practices
.
3) Hold boards by the edges only; do not touch the electronic components or gold
connectors.
4) After removal, always place the boards on a grounded, static-free surface, ESD pad
or in a proper ESD bag. Do not slide the board over any surface
.

NOTE
To determine which board diagram (-20, -40, -50, etc.) matches your module, compare the jumper
locations with the diagrams found above.
10/100 Switching modules
and
Gigabit modules
do not
require any configuration, therefore the boards for those modules are not shown above.
