Connecting the Device to a Network
NetScreen-ISG 2000 27
To cable two NetScreen-ISG 2000 together for HA and connect them to the network:
1. (Optional) Install each NetScreen-ISG 2000 in an equipment rack (see
“Equipment Rack Mounting” on page 14).
2. Make sure that all ON/OFF power supply switches are off.
Note: The provided cabling instructions reproduce the configuration shown above;
however, this is not the only possible HA configuration. In addition, the instructions
assume that all physical ports and interfaces are still set at their default settings. If you
have changed the port and interface configurations, the instructions might not work
properly.
