Chapter 6. IBM System Management Tools one or more PCs over the network. The Magic Packet identifies each specific PC through the unique MAC address assigned to every network interface device. LCCM can broadcast a Magic Packet on local area networks made up of hubs, bridges, and switches. LCCM can also wake a client on the other side of a router if the administrator includes the subnet address of the router. LCCM wraps the subnet address with the Magic Packet so that it can travel across router(s) to the local domain where the client resides before the packet is broadcast on the LAN. As the IBM PC powers on for the first time on the network, it will query the network before booting from its local hard disk drive. LCCM's Scan (discovery) feature will recognize that a new system has been added to the network and respond with a signal that allows the network to gain control of the client and prevents the local operating system from loading. LCCM will then query the client for vital product data through its Systems Management BIOS and Wired for Management/DMI features. LCCM creates a client profile as part of an Individual Client Details record and database with this information (e.g., machine type and serial number, disk, memory size, graphics/video chipset, MAC address, BIOS level and more.) If the PC is equipped with Asset ID, as are select models of IBM client system PCs and IntelliStations, LCCM can also recover any information that has been recorded about the user. Asset ID allows an administrator using a radio-frequency handheld unit to record information to a system EEPROM without even opening the system's packing carton. Otherwise, LCCM assigns a default name to the client during the scan, and can optionally prompt the end user to enter personal information such as his location, department and phone number, etc. If a user is not present, this request will automatically time-out. The data collected is entered automatically into the Individual Client Details record. Flashing the CMOS or BIOS The LCCM administrator can use the information gathered from the client to review its CMOS settings and BIOS level. In some cases, these may need to be changed to ensure consistency across the enterprise or to conform to corporate policies. Since LCCM gains control of the system before the local operating system was booted, LCCM allows administrators to remotely perform low-level maintenance tasks, like flashing the BIOS, that need to occur during the preboot state. The only alternatives are to involve the end user or send a technician to each client. LCCM is complementary to postboot management tools, which need a local operating system running, such as DMI browsers or software change management programs. Installing software Next, the network administrator uses the information that LCCM has gathered about the client to determine the end user's software requirements, including operating system and applications. (When Asset ID is used, this step can be simplified by recording the end user's software profile to the system EEPROM.) The software can come from one of two sources: a compressed software "image" that includes a copy of all of the software needed by the local client, or from installation files located on a file server. In either case, the software can be downloaded to the client without intervention by the user or the administrator. Chapter 6. IBM System Management Tools 45

The Magic Packet identifies each specific PC through the unique
MAC address assigned to every network interface device.
LCCM can broadcast a Magic Packet on local area networks made up of hubs, bridges, and switches.
LCCM can also wake a client on the other side of a router if the administrator includes the subnet address
of the router.
LCCM wraps the subnet address with the Magic Packet so that it can travel across router(s)
to the local domain where the client resides before the packet is broadcast on the LAN.
As the IBM PC powers on for the first time on the network, it will query the network before booting from its
local hard disk drive. LCCM's Scan (discovery) feature will recognize that a new system has been added
to the network and respond with a signal that allows the network to gain control of the client and prevents
the local operating system from loading.
LCCM will then query the client for vital product data through its Systems Management BIOS and Wired
for Management/DMI features.
LCCM creates a client profile as part of an Individual Client Details record
and database with this information (e.g., machine type and serial number, disk, memory size,
graphics/video chipset, MAC address, BIOS level and more.)
If the PC is equipped with Asset ID, as are select models of IBM client system PCs and IntelliStations,
LCCM can also recover any information that has been recorded about the user.
Asset ID allows an
administrator using a radio-frequency handheld unit to record information to a system EEPROM without
even opening the system's packing carton.
Otherwise, LCCM assigns a default name to the client during the scan, and can optionally prompt the end
user to enter personal information such as his location, department and phone number, etc. If a user is not
present, this request will automatically time-out.
The data collected is entered automatically into the
Individual Client Details record.

The LCCM administrator can use the information gathered from the client to review its CMOS settings and
BIOS level.
