a full list of LOM commands supported by the Firepower System, see the Configuring Appliance Settings chapter

in the Firepower Management Center Configuration Guide.

Note:

In some power cycle scenarios, the baseboard management controller (BMC) of a Firepower 7050

connected to the network via the management interface could lose the IP address assigned to it by the DHCP

server. Because of this, Cisco recommends you configure the Firepower 7050 BMC with a static IP address.

Alternately, you can disconnect the network cable and reconnect it, or remove and restore power to the device to

force renegotiation of the link.

Before you can restore an appliance using LOM, you must enable LOM for both the appliance and the user who

will perform the restore. Then, use a third-party Intelligent Platform Management Interface (IPMI) utility to access

the appliance. You must also make sure you redirect the appliance's console output to the serial port.

For more information, see the following sections:



Enabling LOM and LOM Users, page 25



Installing an IPMI Utility, page 26

Enabling LOM and LOM Users

Before you can use LOM to restore an appliance, you must enable and configure the feature. You must also

explicitly grant LOM permissions to users who will use the feature.

You configure LOM and LOM users on a per-appliance basis using each appliance's local web interface. That is,

you cannot use the Management Center to configure LOM on a Firepower device. Similarly, because users are

managed independently per appliance, enabling or creating a LOM-enabled user on the Management Center does

not transfer that capability to users on Firepower devices.

LOM users also have the following restrictions:



You must assign the Administrator role to the user.



The user name may have up to 16 alphanumeric characters. Hyphens and longer user names are not

supported for LOM users.
