1.1.4 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.

Optional Installation Procedure
This section describes the procedure that may be useful to you, depending on your on-site needs and
how you configure your switch. If you want to configure the switch via the CLI, you must first connect the
Console port of the switch to the computer. The cables needed for such connection are provided with the
switch. The computer must be installed with a particular type of terminal simulation software (for example,
WINDOWS HyperTerminal). Set the following parameters for the software: 9600 for baud rate, 8 data bits,
no parity check, 1 stop bit, and no flow control. For details of how to configure the switch via CLI, see the
CLI section in the configuration guide.
Never stare into the optical module Tx ends and the connected fiber
jumpers to avoid injuries to your eyes.
The first time you connect the power supply, please ensure that the power
supply matches the power requirements of the switch to avoid damaging
the switch.
You must use the 3-pin power socket with a ground end, and the distance
between the power socket and the switch should be no more than 1.8 m.
For more reliable grounding, ground the grounding terminal at the rear
panel of the switch.
Connect the grounding hole at the back of the switch to the grounding system of
the equipment room.
Connect the power supply of the switch.
Check the "Status" LED on the front panel. If it is flashing, the power supply is
normal and the switch starts initialization.
