AC Power Connection

DS4000/DS4001 uses 220VAC power supply by default. Please read the power input specifications for the detailed information.

Insert one end of the power cable provided in the accessory kit into power source socket, and the other end to the power socket (with overload and leakage protection).
Check the power status indicator on the front panel. The corresponding PWR indicator should light. DS4000/DS4001 is self-adjustable to the input voltage. As soon as the input voltage is in the range printed on the switch surface, the switch can operate correctly.
When the Ethernet switch is powered on, it executes the self-test procedure and starts.
