Chapter 2 Installation Preparation

2.1 Caution

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 BDCOM
S2928E, you have to open the power switch after the power is cut down for three to
five seconds.
Avoid severe collision or falling down from the height to protect the internal parts of
the switch.
You should use correct outside ports to connect the switch of BDCOM S2928E. Do
not insert the Ethernet plug into the console port. Similarly, do not insert the console
cable into the Ethernet port (RJ45 8-line socket). The above operations and other
wrong operations may cause damage to the internal components of the port.
Note:
1) When you plug or dial out the power line, keep the power line horizontal with the
power socket.
2) When the lifetime of our products ends, please handle them according to national
laws and regulations, or send these products to our company for collective
processing.
