3.
Feed AC power into the system.
The PSU will immediately output 12V & 5VSB to the system with a 220V, AC power source. The
PSU has a built-in 15 amperes, fast acting fuse based on the PSU maximum capacity, which will
act as a second tier system protection in case the power distribution unit’s fuse is not
functioning.
4.
Verify that the power supply is operating.
If connected correctly, when turned on, the LED on the PSU will light up with a solid Green
color designating normal operation.
Note
If only a 110V AC power source is available, the S9705-48D can still be powered with both
PSUs providing 1000 watts each for a total output of 2000 watts. However, in this case, if
one PSU stops functioning, the power output would be inefficient to sustain the router
’s
operation.
