Chapter 2 Installation Preparation
2.1 Cautions
Similar to other electronic products, the semiconductor chip easily gets damaged if you power on
and off abruptly and frequently. To restart up the switch of DS-3E2300P, you have to open the
power on-off three or five seconds after the power is cut off.
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 DS-3E2300P. Do not insert the Ethernet plug into
the console port (RJ45 8-line socket). Similarly, do not insert the console cable into the console
port (RJ45 8-line socket).
When you plug or dial out the power line, keep the power line horizontal with the power
socket.
When the lifetime of our products ends, handle them according to national laws and
regulations, or send these products to our company for collective processing.
