Updating the fru and sensor data records

This solution is less expensive than a dedicated LAN connection but also has limited bandwidth.Different types of sensors built into the computer system report to the BMC on parameters such as temperature, cooling fan speeds, power status, operating system (OS) status, etc.The BMC monitors the sensors and can send alerts to a system administrator via the network if any of the parameters do not stay within pre-set limits, indicating a potential failure of the system.For example, IPMI provides a way to manage a computer that may be powered off or otherwise unresponsive by using a network connection to the hardware rather than to an operating system or login shell.The specification is led by Intel and was first published on September 16, 1998.

IPMI prescribes only the structure and format of the interfaces as a standard, while detailed implementations may vary.

An implementation of IPMI version 1.5 can communicate via a direct out-of-band local area network (LAN) or serial connection or via a side-band local area network (LAN) connection to a remote client.

system power-down and rebooting, or configuring watchdog timers.

The standard also defines an alerting mechanism for the system to send a simple network management protocol (SNMP) platform event trap (PET).

As a message-based, hardware-level interface specification, IPMI operates independently of the operating system (OS) to allow administrators to manage a system remotely in the absence of an operating system or of the system management software.

Thus IPMI functions can work in any of three scenarios: System administrators can use IPMI messaging to monitor platform status (such as system temperatures, voltages, fans, power supplies and chassis intrusion); to query inventory information; to review hardware logs of out-of-range conditions; or to perform recovery procedures such as issuing requests from a remote console through the same connections e.g.
