20	Version change	Discrete (0x6f), "reserved" (0x2b)	Firmware update event	IPMC reports event after the FW update/cold reset.
21	System event	Discrete (0x6f, “System Event” (0x12)	Tracks IPMC resets.	Every time IPMC takes a reset, an event is sent to Shelf manager. This sensor supports SOL based NetConsole use.
22	P48V alarm	Discrete (0x6f, “System Event” (0x12)	Monitors the 48V rails.	Monitors the 48V rails and reports the state via state bits. IPMC shall directly read Power Module’s voltage registers to determine presence of power rails. If a voltage less than 38 volts, rail is considered to be absent. 0x1 (Bit 0 set) Both rails absent. 0x2 (Bit 1 set) Only Rail A is present. 0x4 (Bit 2 set) Only Rail B is present. 0x8 (Bit 3 set) Both Rail A and B are present.
23	Sys fw progress	Discrete (0x6f), "System Firmware Progress" (0x0f),	Monitors the system firmware progress states.	This sensor monitors the firmware progress. The system firmware sends the firmware progress events to the system event log by way of the IPMC.

25	Slot power	Threshold (0x01), "Voltage" (0x02)	Tracks the power being consumed by the slot.	This sensor is for information purposes and does not generate any events. The nominal value range for this sensor is from 5 Watts to ~300 Watts. The nominal value is set at 150 Watts. This is not indicative of a typical usage. Power usage shall depend upon the state of the blade and state of the OS running.
26	Thermal trip	Discrete (0x6f, “System Event” (0x12)	Reports upper non-recoverable (UNC) threshold violation events.	This sensor sends event notice if UNC threshold is reached.
