4.2 Precautions Before Starting the Installation
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 block the air vents of the device. Otherwise, the internal heat is not discharged,
which may cause a fire. Keep more than 50 mm of space from the air vents.
Do not put anything that is 5 kg or more on the switch. The switch might be damaged or
fall over, causing injury.
Make sure to wear the antistatic wrist strap. Handling the device without the antistatic wrist strap
may damage the device due to electrostatic discharge.
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 exact length needed to maintain the
switch. The extra cable should be rolled near the switch. When optical fiber and other interface
cables are used together, be sure to not to apply excessive stress on the optical fibers.
