Connecting the Device to a Network 25
Chapter 2: Installing
To connect the ISG 2000 to the network, do the following:
1. (Optional) Install the ISG 2000 in an equipment rack (see “Equipment Rack
Mounting” on page 26).
2. Make sure that the ISG 2000 ON/OFF switches on the dual power supplies are
in the OFF position.
3. Connect the power cables, included in the product package, to the ISG 2000
power supplies and to a power source.
4. Connect an RJ-45 or gigabit ethernet cable from the ethernet1/1 interface to an
external router (possibly a DSL or cable modem) in the Untrust zone.
5. Connect an RJ-45 or gigabit ethernet cable from the ethernet1/2 port to a hub
or Layer 2 switch in the DMZ.
6. Connect an RJ-45 or gigabit ethernet cable from the ethernet2/1 port to a hub
or Layer 2 switch in the Trust zone.
7. Connect an RJ-45 ethernet cable from the MGT interface on the ISG 2000 to a
hub or Layer 2 switch that leads to the administrators’ workstations.
8. Press the ON/OFF switches on the dual power supplies to the ON position.
9. After the ISG 2000 boots up, check that the Power, Status, and Link LEDs light
up as follows:
The Power LED for each deployed power supply glows green.
The Status LED blinks green.
The top Link Status LEDs for each interface glows or blinks green. (For
more details about interpreting the Link Status LEDs, see “LED Dashboard”
on page 32.)
NOTE: Whenever you deploy both power supplies in a ISG 2000, connect each power
supply to a different power source if possible. If one power source fails, the other
source might still be operative.
NOTE: Check your router, hub, switch, or computer documentation to see if these devices
require any further configuration. In addition, see if it is necessary to switch off
the power to any new device you add to the LAN.
