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 gateway is operating.
•
Before you remove the optical fiber connector from a fiber port, execute the
shutdown
command in interface view to shut down the port.
CAUTION:
•
Insert optical fiber caps into open optical fiber connectors to protect them from contamination and
ESD damage.
•
Insert dust plugs into open fiber ports and transceiver module ports to protect them from
contamination and ESD damage.
Examining the installation site
The gateway must be used indoors. To ensure the correct operation and long service life of your
gateway, the installation site must meet the requirements in this section.
Weight support
Make sure the floor can support the total weight of the rack, chassis, and accessories. Additionally,
the floor loading plan must also consider system expansion, such as adding more modules. For
more information, see "Appendix B Technical Specifications."
Space
For easy installation and maintenance, make sure the following requirements are met:
•
Make sure the rack has enough space (in height and depth) to accommodate the gateway.
•
The rack allows front and rear access to the gateway.
•
A minimum clearance of 1.2 m (3.94 ft) is reserved between the rack and walls or other devices.
For more information about the chassis dimensions, see "Appendix B Technical Specifications."
