Using system management
This topic is primarily intended for the network administrators.
Your computer is designed for manageability, so that you can redirect more resources to better meet
your business objectives.
This manageability, known as total cost of ownership (TCO), enables you to remotely operate client
computers in the same way as you operate your own computer, such as turning on a client computer,
formatting a storage drive, and installing a program.
Once the computer is configured and operational, you can manage it by using the software and the
manageability features that are already integrated into the client computer and the network.
Desktop Management Interface
The UEFI BIOS of your computer supports an interface called System Management BIOS (SMBIOS)
Reference Specification, version 2.8 or later. SMBIOS provides information about the hardware components
of your computer. It is the responsibility of the UEFI BIOS to provide information about itself and the devices
on the system board. This specification documents the standards for getting access to this BIOS information.
Preboot eXecution Environment
The Preboot eXecution Environment (PXE) technology makes the computer more manageable by enabling
the computer to start from a server. Your computer supports the personal computer functions that PXE
requires. For example, with the appropriate LAN card, your computer can be started from the PXE server.
Note: The Remote Initial Program Load (RIPL or RPL) function cannot be used with your computer.
Wake on LAN
The network administrator can turn on a computer from a management console by using the Wake on
LAN feature.
When the Wake on LAN feature is enabled, many operations, such as data transfer, software updates, and
flash updates of the UEFI BIOS, can be done remotely without remote attendance. The updating process
can perform after normal working hours and on weekends, so that the users are not interrupted during work,
and the LAN traffic is kept to a minimum. It saves time and increases productivity.
If the computer is turned on through Wake on LAN, the computer starts follow the Network Boot sequence.
Asset ID EEPROM
The Asset ID EEPROM contains information about the computer configuration and the serial numbers of
the key components. It also includes a number of blank fields where you can record information about
the end users in your network.
