2.2.1 Safety Suggestions
To avoid personal injury and equipment damage, read safety suggestions carefully before you install each device.
The following safety suggestions do not cover all possible dangers.
Installation
Keep the chassis clean and free from any dust.
Do not place devices in a walking area.
Do not wear loose clothes or accessories that may be hooked or caught by devices during installation and
maintenance.
Movement
Do not frequently move devices.
When moving devices, keep the balance and avoid hurting legs and feet or straining the back.
Before moving devices, turn off all power supplies and dismantle all power modules.
Electricity
Observe local regulations and specifications when performing electric operations. The operators must be
qualified.
Before installing the device, carefully check any potential danger in the surroundings, such as ungrounded
power supply, and damp or wet ground or floor.
Before installing the device, find out the location of the emergency power supply switch in the room. First cut
off the power supply in the case of an accident.
Try to avoid maintaining the switch that is powered on alone.
Make a careful check before you cut off the power supply.
Do not place the equipment in a damp location. Do not let any liquid enter the chassis.
Static Discharge Damage Prevention
To prevent damage from static electricity, pay attention to the following points:
Properly ground grounding screws on the back panel of the device; use a three-wire single-phase socket
with the protective earth wire (PE) as the AC power socket.
Prevent indoor dusts.
Ensure proper humidity conditions.
Laser
Some devices support varying models of optical modules that are Class I laser products sold on the market.
Improper use of optical modules may cause damage. Therefore, pay attention to the following points when you
use them:
When a fiber transceiver is working, ensure that the port has been connected to an optical fiber or is covered
with a dust cap, to keep out dust and avoid burns.
When the optical module is working, do not pull out the fiber cable or look directly into a transceiver. The
transceiver emit laser light that can damage your eyes.
