power on and off abruptly and frequently. To restart up the switch of DS-3D2228P, 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.

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).
Note:
1) When you plug or dial out the power line, keep the power line horizontal with the
