Chapter 8 Restoring a Firepower System Appliance to Factory Defaults
Setting Up Lights-Out Management
Setting Up Lights-Out Management
If you need to restore a Firepower device to factory defaults and do not have physical access to the
appliance, you can use Lights-Out Management (LOM) to perform the restore process. Note that you can
use Lights-Out Management on the default (
eth0
) management interface only.
Note
The baseboard management controller (BMC) for a Firepower 71xx, Firepower 82xx, or a Firepower or
AMP 83xx device is only accessible via 1Gbps link speeds when the host is powered on. When the
device is powered down the BMC can only establish Ethernet link at 10 and 100Mbps. Therefore if LOM
is being used to remotely power the device, connect the device to the network using 10 and 100Mbps
link speeds only.
The LOM feature allows you to perform a limited set of actions on a Firepower device, using a Serial
over LAN (SOL) connection. With LOM, you use a command line interface on an out-of-band
management connection to perform tasks such as viewing the chassis serial number, or monitoring
conditions such as fan speed and temperature.
The syntax of LOM commands depends on the utility you are using, but LOM commands generally
contain the elements listed in the following table.
.
Therefore, for IPMItool:
ipmitool -I lanplus -H
IP_address
-U
username
command
Or, for ipmiutil:
ipmiutil
command
-V4
-J3 -N
IP_address
-U
username
-P
password
Note that the
chassis power off
and
chassis power cycle
commands are not valid on 70xx Family
appliances. For a full list of LOM commands supported by the Firepower System, see the Configuring
Appliance Settings chapter in the
Firepower Management Center Configuration Guide
.
