Chapter 2 Installation Preparation
2.1 Caution of Usage
Similar to other electronic products, the semiconductor chip easily gets damaged if you
power on or off abruptly and frequently. To restart up the switch of S3740, you have to open
the power on-off after the power is cut down for three to five seconds.
Avoid severe collision or falling down from the height to protect the parts in the switch.
Use correct outside ports to connect the switch of S3740. Do not put the Ethernet plug into
the console port (RJ45 8-line socket). Similarly, do not put the console cable into the console
port (RJ45 8-line socket).
Note:
1) When you plug or dial the power line, keep the power line horizontal with the power
socket.
