6 Installation and maintenance
6.1 Unpacking
After the equipment arrives, unpack and check it before installation. Items to be checked are as
follows:
● The external package is in good condition or not. If it is damaged seriously, please contact our
after-sale service department immediately for solving.
●
Based on the package list, verify the items one by one. If there is any serious damage on the
surface or any accessories missed, please contact the installation person or directly contact our
after-sale service department.
● Please check carefully whether the equipment type and quantity are in conformity with what you
ordered.
●
Check the power supply mode.
6.2 Installation
●
Fix the equipment on the 19” rack-mount.
●
According to the manual, connect power supply with the power cable. Pay attention to the
power polarity.
●
According to actual situation, make and connect relevant cable (2M, RS-232). Do not connect
the TX and RX optic cables wrongly.
●
Connect the TX and RX optical fibers (or patch cords) to the optical RX and TX connectors in
the equipment. Do not connect the TX and RX fibers wrongly. Check whether the fiber head is
clean or not. Insert the optical fiber (or patch cords) and make sure the connection is good. (The
bending radius of optical fiber must
≥ 50mm.)
● Use a multimeter to check the power polarity and voltage is in conformity with equipment
requirements or not. This is especially recommended for 48V power supply version.
●
After all installation and check, turn on the power supply switch.
● Check whether the equipment indicator light is the same as the actual situation (Refer to
relevant chapters in the manual.).
Note: When install single fiber Optic Multiplexers, you must ensure they are same TX and RX
wavelength, for example: TX:1550nm, RX:1310nm must match with TX:1310nm, RX:1550nm
6.3 Notices for Installation
1) Avoid strong vibration and mechanical damage during transportation and installation.
2) Place the optical fibers reasonable. The bending radius of optical fiber must
≥ 50mm.
3) Check whether the voltage and polarity is in conformity with the marks on the rear panel before
supplying power. Otherwise, it may cause permanent damage to the equipment.
4) The optical fiber connector cannot be contaminated. Clean the fiber head with alcohol before use.
Otherwise, it may affect the transmission distance. If the optical fiber connector is connected
wrongly, it may cause more power consumption. Adjust the connector according to the actual
situation.
