4.2 Precautions before starting an installation
When installing the Switch on a table, position the Switch horizontally. If the Switch is
positioned vertically or leaned against a wall, the Switch might fall, which could
result in injury or damage.
For switches on tables, avoid an unstable places including wobbly tables and tilted
surfaces. Install the switch horizontally on a solid table. Otherwise, the switch might
fall and cause injury.
Do not place anything on the Switch. Doing so might damage the Switch
Furthermore, the Switch might fall, or become unbalanced, resulting in injury.
Do not block the ventilation slots. Otherwise, internal heat is not discharged, which
may cause damage. Maintain a space of at least 50 mm around the ventilation slots.
Be sure to wear an antistatic wrist strap. If you handle the Switch without wearing an
antistatic wrist strap, the Switch might be damaged by static electricity.
Install the device somewhere where the LEDs can be easily seen.
Route the cables through ducts or cover them for protection. Optical fiber requires
special handling; lay the cables with a bend radius of more than 100 mm on the
major axis and 50 mm on the minor axis, and protect them with metal covers.
The optical fiber cables should be 3 m longer than the length needed to maintain the
device. The extra part should be wound near the device. When optical fiber and
other interface cables are used together, be sure to not to apply excessive stress on
the optical fibers.
