Chapter 4 Installing IDS-4235 and IDS-4250

Installing IDS-4235 and IDS-4250

Step 4

Attach the network cables.

IDS-4225 and IDS-4250 have the following interfaces:

•

GigabitEthernet0/0 is the sensing port.

•

GigabitEthernet0/1 is the command and control port.

•

GigabitEthernet1/0 and GigabitEthernet2/0 are the optional SX (fiber NIC) sensing ports (with two
SX cards installed).

•

GigabitEthernet2/0 and GigabitEthernet2/1 are the optional XL card sensing ports.

•

FastEthernet1/0, FastEthernet1/1, FastEthernet1/2, and FastEthernet1/3 are the optional 4FE card
sensing ports.

•

GigabitEthernet1/0 or GigabitEthernet2/0 (depending on the slot it is installed in) is the optional
(copper NIC) sensing port (with one TX card installed). Only one optional TX adapter is supported.

Step 5

Power on the appliance.

Caution

If the BIOS version is earlier than A04, you must apply the BIOS upgrade before installing Cisco IPS
5.0 on the appliance. For the procedure, see

Upgrading the BIOS, page 4-5

Step 6

Initialize the appliance.

For the procedure, see

Initializing the Sensor, page 9-2
