Power Supplies

A NetScreen-200 Series device can have an AC power supply or a DC power supply.
The DC power supply can operate on one or two DC feeds ranging from -36V to -60V.
When you use two feeds, they share the load. If one feed fails, the other automatically
assumes the full load.
The internal fuse for the DC power supply is a 3.15A/250V, fast-acting fuse. This is not
replaceable.
