5.2. Connecting the VX-2000DS to SX-2000 System
[When using a redundant power system*]
In this connection example, 2 power supply units are used. Even if one of the 2 units fails or its power supply
line is broken, power is still supplied from the other unit, preventing the system from going down.
* A method of connecting separate power sources to each power input or connecting the commercial power
supply and backup power supply separately to each power input to prevent the system from going down
when a cable is broken or power fails.
