switch. When you plug the RJ-45 connector, you should hear a “click”, which means that the
connector is plugged tightly.
Do not insert a phone connector into the RJ-45 port, as this may damage
the switch.
Ensure that each twisted pair cable does not exceed 100 m in length.
2.4.2 Connecting Optical Fibers
Connect the optical module on the switch by using an optical fiber whose connector matches
that of the optical module. When you are doing this, connect the RX end of one party to the
TX end of the other party to ensure correct Rx/Tx channel connection.
Do not stare into the 1000BASE-SX/LX ports as invisible laser radiation
from them may hurt your eyes.
2.4.3 Laser Safety
Most optical transceiver modules supported by the DGS-3610 series are Class I laser
products. Therefore, pay attention to the following during your use of this product:
Do not stare into the optical module Tx ends or the connected fiber jumpers, as invisible
laser radiation from them may hurt your eyes.
Unused optical modules should have their jumper ports covered with dust plugs, as
dust may pollute or damage the laser connectors.
Never stare into the optical module Tx ends and the connected fiber
jumpers to avoid injuries to your eyes.
2.5 Connecting Power Cables to the
Switch
Please carefully read the following warning statements before you connect the power supply
to the switch.
The first time you connect the power supply, please ensure that the power
supply matches the power requirements of the switch to avoid damaging
