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 the temperature in a variety of locations in the chassis and in attached system(s).
•Fan Sensor — Monitors fans in various locations in the chassis and in attached system(s).
•Voltage Sensor — Monitors voltages across critical components in various chassis locations and in attached system(s).
•Current Sensor — Monitors the current (or amperage) output from the power supply (or supplies) in the chassis and in attached system(s).
•Chassis Intrusion Sensor — Monitors intrusion into the chassis and attached system(s).
•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 attached system(s). For example, redundancy allows a second or nth 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 attached system(s).
•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 in attached system(s).
•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.
•Processor Sensor — Monitors the processor status in the system.
•Pluggable Device Sensor — Monitors the addition, removal, or configuration errors for some pluggable devices, such as memory cards.
•Battery Sensor — Monitors the status of one or more batteries in the system.
•SD Card Device Sensor — Monitors instrumented Secure Digital (SD) card devices in the system.
