108 Glossary
server module
A modular system component that functions as an
individual system. To function as a system, a server
module is inserted into a chassis which includes power
supplies, fans, a system management module, and at
least one network switch module. The power supplies,
fans, system management module, and network switch
module are shared resources of the server modules in
the chassis. See modular system.
service tag number
A bar code label that identifies each system in the event
that you need to call for customer or technical support.
SMART
Acronym for Self-Monitoring Analysis and Reporting
Technology. A technology that allows hard drives to
report errors and failures to the system BIOS, which
then displays an error message on the screen. To take
advantage of this technology, you must have a
SMART-compliant hard drive and the proper support
in the system BIOS.
SMBIOS
Acronym for system management BIOS.
SNMP
Abbreviation for Simple Network Management
Protocol. SNMP, a popular network control and
monitoring protocol, is part of the original TCP/IP
protocol suite. SNMP provides the format in which
vital information about different network devices, such
as network servers or routers, can be sent to a
management application.
SNMP trap
A notification (event) generated by the RAC or ESM
that contains information about state changes on the
managed system or about potential hardware problems.
SOL
Abbreviation for Serial Over LAN. SOL enables
suitably designed servers to transparently redirect the
serial character stream of a baseboard UART to/from a
remote client over a shared LAN. The architecture
requires software running on the managed system's
BMC and client software running on a management
station and/or a central network proxy.
support commands
Commands that specify how an action should be
performed.
syntax
The rules that dictate how you must type a command
or instruction so that the system understands it.
A variable's syntax indicates its data type.
system configuration information
Data stored in memory that tells a system what
hardware is installed and how the system should be
configured for operation.
system diskette
System diskette is a synonym for bootable diskette.
system memory
System memory is a synonym for RAM.
System Setup program
A BIOS-based program that allows you to configure
your system's hardware and customize the system's
operation by setting such features as password
protection and energy management. Some options in
the System Setup program require that you reboot the
system (or the system may reboot automatically) in
order to make a hardware configuration change.
Because the System Setup program is stored in
NVRAM, any settings remain in effect until you change
them again.
