Laser safety

WARNING!
Disconnected optical fibers or transceiver modules might emit invisible laser light. Do not stare into
beams or view directly with optical instruments when the switch is operating.
•
Use the shutdown command to disable an interface before you remove a transceiver module
from the interface.
•
Insert a dust cap into any open optical fiber connector and a dust plug into any open fiber port or
transceiver module port to protect them from contamination and ESD damage.

Examining the installation site

The device can only be used indoors. To ensure correct operation and a long lifespan for your device,
install it in an environment that meets the requirements described in the following subsections.

Temperature and humidity

Make sure the temperature and humidity in the equipment room meet the requirements described in
Table1-1.
•
Lasting high relative humidity can cause poor insulation, electricity leakage, mechanical
property change of materials, and metal corrosion.
•
Lasting low relative humidity can cause washer contraction and ESD and cause problems
including loose mounting screws and circuit failure.
•
High temperature can accelerate the aging of insulation materials and significantly lower the
reliability and lifespan of the device.

Cleanliness

Dust buildup on the chassis might result in electrostatic adsorption, which causes poor contact of
metal components and contact points, especially when indoor relative humidity is low. In the worst
case, electrostatic adsorption can cause communication failure.
