Ethernet Interfaces
Each Ethernet port is a 10/100 auto-sensing interface with two link LEDs. The left LED
indicates network traffic, and the right LED indicates an active network link.
THE REAR PANEL
The figure below shows the rear panel of a NetScreen-200 Series device (with an AC
power supply).
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.
Note: Certain export restrictions may apply to international customers. Check with your
sales representative.
