To cable two NetScreen-50 devices together for HA and connect them to the network:
1.
(Optional) Install the NetScreen-50 devices in an equipment rack (see
“Equipment Rack Mounting” on page 8
).
2.
Make sure that all ON/OFF power supply switches are OFF.
3.
Connect the power cables on each NetScreen-50 to a power source.
4.
Connect a 10/100 Base-T cable from the HA1 zone interface (Ethernet port 4) on
Device 1 to the HA2 zone interface (Ethernet port 4) on Device 2.

5.
On Device 1, connect a crossover cable from the Trust zone interface (Ethernet
port 1) to the switch labeled “Switch 3.”
6.
On Device 1, connect a straight-through cable from the Untrust zone interface
(Ethernet port 3) to the switch labeled “Layer 3 switch 1.”
'HYLFH
7.
On Device 2, connect a crossover cable from the Trust zone interface (Ethernet
port 1) to the switch labeled “Switch 4.”
8.
On Device 2, connect a straight-through cable from the Untrust zone interface
(Ethernet port 3) to the switch labeled “Layer 3 switch 2.”

9.
Cable together the switches labeled “Switch 3” and “Switch 4.”
10.
Cable together the switches labeled “Layer 3 switch 1” and “Layer 3 switch 2.”
11.
Cable the switches labeled “Layer 3 switch 1” and “Layer 3 switch 2” to routers.
12.
Turn the power switches for all devices ON.
For more advanced HA configurations, see the NetScreen Concepts & Examples ScreenOS
Reference Guide.
Note:
The cabling instructions given below reproduce the configuration shown previously.
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 below might not work
properly.
Note:
Whenever you deploy two NetScreen-50 devices in an HA cluster, connect
each to a different power source, if possible. If one power source fails, the other
source might still be operative.
Note:
The switch ports must be defined as 802.1Q trunk ports, and the external
routers must be able to use either Hot Standby Router Protocol (HSRP) or Virtual
Router Redundancy Protocol (VRRP). For the best configuration method, see the
documentation for your switch or router.
