10 Introduction
Server Administrator generates events based on status changes in the
following sensors:
Temperature Sensor
— Helps protect critical components by alerting the
systems management console when temperatures become too high inside
a chassis; also monitors a variety of locations in the chassis and in any
attached systems.
Fan Sensor
— Monitors fans in various locations in the chassis and in any
attached systems.
Voltage Sensor
— Monitors voltages across critical components in various
chassis locations and in any attached systems.
Current Sensor
— Monitors the current (or amperage) output from the
power supply (or supplies) in the chassis and in any attached systems.
Chassis Intrusion Sensor
— Monitors intrusion into the chassis and any
attached systems.
Redundancy Unit Sensor
— Monitors redundant units (critical units such
as fans, AC power cords, or power supplies) within the chassis; also monitors
the chassis and any attached systems. For example, redundancy allows a
second or
n
th fan to keep the chassis components at a safe temperature
when another fan has failed. Redundancy is normal when the intended
number of critical components are operating. Redundancy is degraded when
a component fails, but others are still operating. Redundancy is lost when
there is one less critical redundancy device than required.
Power Supply Sensor
— Monitors power supplies in the chassis and in any
attached systems.
Memory Prefailure Sensor
— Monitors memory modules by counting the
number of Error Correction Code (ECC) memory corrections.
Fan Enclosure Sensor
— Monitors protective fan enclosures by detecting
their removal from and insertion into the system, and by measuring how
long a fan enclosure is absent from the chassis. This sensor monitors the
chassis and any attached systems.
AC Power Cord Sensor
— Monitors the presence of AC power for an
AC power cord.
Hardware Log Sensor
— Monitors the size of a hardware log.
