Connecting the Cisco NAC Appliance
To perform initial configuration, you will need to connect to your CAM and CAS Cisco NAC
Appliances and access the command line. The following steps describe how to connect to either
appliance.
Step 1
Access the Cisco NAC Appliance command line for each machine in one of two ways:
a.
Connect a monitor and keyboard directly to the machine via the keyboard/video monitor
connectors on the back panel of the machine (preferred method).
b.
Connect a serial cable from a workstation (PC/laptop) to the machine and open a serial
connection on the workstation using terminal emulation software (such as HyperTerminal or
SecureCRT). For details, see Connecting Serially to the Cisco NAC Appliance, page 27.
Step 2
Connect a straight-through Category 5 Ethernet cable to the
eth0 (NIC1)
10/100/1000
Ethernet port on the back panel of the Cisco NAC Appliance (CAM or CAS) and to your local
area network.
Step 3
Additionally, for the CAS appliance:
a.
If planning to configure the CAS as a
Virtual Gateway
—either In-Band (IB) or Out-of-Band
(OOB)—
do not connect
the untrusted interface (
eth1 (NIC2)
) of the CAS until
after
you have
added the CAS to the CAM from the web administrator console (and, for Central
Deployments, configured VLAN Mapping) to prevent network connectivity issues. For
details, see the
Cisco NAC Appliance - Clean Access Server Installation and Configuration
Guide, Release 4.5(1)
.
b.
If planning to configure the CAS as a
Real-IP Gateway
(or
NAT Gateway
for testing), connect
a straight-through Category 5 Ethernet cable to the
eth1 (NIC2
) 10/100/1000 Ethernet port
on the back panel of the CAS and to your local area network.
Step 4
Connect the AC power cord to the back panel of the Cisco NAC Appliance and to a grounded
AC outlet.
Step 5
Power on the Cisco NAC Appliance by pressing the power button on the front of the
appliance. The diagnostic LEDs will flash a few times as part of the power-on self-test (POST).
Status messages are displayed on the console as the appliance boots up.

Utility, page 32.
