You can later configure the device manager management access from other interfaces; see the Cisco Secure
Firewall Device Manager Configuration Guide.
Step 3 Connect the outside network to the Ethernet1/1 interface (labeled WAN).
By default, the IP address is obtained using IPv4 DHCP and IPv6 autoconfiguration, but you can set a static
address during initial configuration.
Step 4 Connect other networks to the remaining interfaces.
Power on the Firewall
System power is controlled by a rocker power switch located on the rear of the device. The power switch is
implemented as a soft notification switch that supports graceful shutdown of the system to reduce the risk of
system software and data corruption.
The first time you boot up the threat defense, initialization can take approximately 15 to 30 minutes.
Note
Before you begin
It's important that you provide reliable power for your device (for example, using an uninterruptable power
supply (UPS)). Loss of power without first shutting down can cause serious file system damage. There are
many processes running in the background all the time, and losing power does not allow the graceful shutdown
of your firewall system.
Procedure
Step 1 Attach the power cord to the device, and connect it to an electrical outlet.
Step 2 Turn the power on using the standard rocker-type power on/off switch located on the rear of the chassis,
adjacent to the power cord.
Step 3 Check the Power LED on the back of the device; if it is solid green, the device is powered on.
Step 4 Check the Status LED on the back of the device; after it is solid green, the system has passed power-on
diagnostics.
