Laser Safety

Among the modules supported by the DES-7210/7206, there are a great number of optical
modules that are Class I laser products. Therefore, pay attention to the following during your
use of this product:

When a fiber transceiver works, ensure that the port has been connected with an optical
fiber or is covered with a dust cap, to keep out dust and avoid burning your eyes.

Do not stare into any optical port.

Installation Site Requirements

The DES-7210/7206 must be used indoors. To ensure the normal working and a prolonged
useful file of the equipment, the installation site must meet the following requirements.
2.2.1

Requirements for Rack Mounting

If you plan to mount the DES-7210/7206 in a frame, you must verify that the frame meets the
following conditions:

Install the switch in an open cabinet as much as possible. If you install the switch inside
a closed cabinet, please make sure that the cabinet has a good ventilation and heat
dissipation system.

Make sure that the cabinet is firm enough to bear the weight of the DES-7210/7206 and
its installation accessories.

Make sure that the dimensions of the cabinet spare certain space for the installation of
the front, rear, left and right panels of the DES-7210/7206 for the sake of heat
dissipation.

The frame should be properly grounded.
2.2.2

Ventilation Requirements

Figure 2-3 and Figure 2-4 show the ventilation requirements of the DES-7210/7206. You
must ensure that sufficient spacing is reserved at the ventilation openings to ensure the
normal working of ventilation. After various cables have been connected, they should be
arranged into bundles or placed on the cabling rack, to avoid blocking the air inlets.
2-4
Do not stare into any optical port under any circumstances, as this may
cause permanent damage to your eyes.
