or walking across a carpeted floor may cause you to acquire a static electrical charge.

To protect your device, always:

Touch the metal chassis of your computer to ground the static electrical charge before you pick up the circuit device.

Pick up the device by holding it on the left and right edges only.

If you need to connect this device to an outdoor device, add an arrester on the cable between the outdoor device and this device.

NOTE: The switch is indoor device; if it will be used in an outdoor environment or connects with an outdoor device, you must use

a lightning arrester to protect the switch.

WARNING:

Self-demolition on the product is strictly prohibited. Damage caused by self-demolition will be charged repairing fees.

Do not place product at outdoor or sandstorm..

Before installation, make sure the input power supply and product specifications are compatible with each other.

To reduce the risk of electric shock, disconnect all AC or DC power cord and RPS cables to completely remove power from the unit.

Before importing/exporting a configuration, make sure the firmware version is always the same.

After a firmware upgrade, the switch will replace the configuration automatically with the latest firmware version.

WARNING: EYE HAZARD! The SFP modules are Class 1 laser devices. Do not look direcly at the beam coming from the transmit

port.
