IMPORTANT:
For a switch that requires power supply redundancy, install the same number of sub power supplies in the
two power frames.
Installing a sub power supply
1. Pull the handle of a sub power supply downward to the unlock position.
2. Gently push the sub power supply into the AC power frame (NEPS3500-A) until the rear side of the
sub power supply makes close contact with the power frame backplane.
3. Push the handle upward so that the handle locks the sub power supply in place.
