SAS

to security protocols or authentication, SAS is Secure Authentication Services.
When referring to computer peripheral devices that employ a serial (one bit at a time)
means of digital data transfer over thin cables, SAS is Serial-attached SCSI.
SCSI
Acronym for small computer system interface. An I/O bus interface with faster
data transmission rates than standard ports. You can connect up to seven devices
(15 for some newer SCSI types) to one SCSI interface.
SEL
Acronym for system event log.
serial port
An I/O port used most often to connect a modem to your system. You can usually
identify a serial port on your system by its 9-pin connector.
settings
Settings are conditions of a manageable object help to determine what happens
when a certain value is detected in a component. For example, a user can set the
upper critical threshold of a temperature probe to 75 degrees Celsius. If the probe
reaches that temperature, the setting results in an alert being sent to the
management system so that user intervention can be taken. Some settings, when
reached, can trigger a system shutdown or other response that can prevent damage
to the system.
