> · Power LED: glows solid green when power is supplied to the NetScreen-5.
> · Status LED: glows solid green when NetScreen-5 is first powered up and the unit first performs diagnostics. Then the unit goes into a startup phase, which takes up to one minute to complete. During startup, the LED blinks orange, after which the LED blinks green. If an error is detected, then the LED illuminates red.
> · Diagnostics Port: DB9 serial port connector for local diagnostics.
> · Trusted Port: Connect the NetScreen-5 to the LAN using a twisted pair cable with RJ45 connectors.
> · Untrusted Port: Connect the NetScreen-5 to the router using a twisted pair cable with RJ45 connectors.
