If this voltage is out of spec or goes to zero, many components on CP3260 will not function. Therefore, CP3260 will not function. The IPMC will be alive if 3.3V STBY is up. Supplies: Multiple support devices

10

3.3V STBY

Threshold (0x01), "Voltage" (0x02)

Threshold (0x01), "Voltage" (0x02)

Voltage measurement of 3.0 VBAT/STBY power rail

If this voltage is out of spec or goes to zero, the on blade server battery is bad or missing. The battery is not required for CP3260 or the RTM to function correctly. Supplies: 3.3V STBY

12

1.0V VDD

Threshold (0x01), "Voltage" (0x02)

Voltage measurement of 1.0V VDD power rail

If this voltage is out of spec or goes to zero, many components on CP3260 will not function. Therefore, CP3260 will not function. The IPMC will be alive if 3.3V STBY is up. Supplies: Multiple support devices, service processor

13

1.1V CPU

Threshold (0x01), "Voltage" (0x02)

Voltage measurement of 1.1V CPU power rail

If this voltage is out of spec or goes to zero, the CPU or HOST will not function. If all other power rails are up, the Service processor and IPMC will still function. Supplies: CPU core

14

VDD 1.1V

Threshold (0x01), "Voltage" (0x02)

Voltage measurement of VDD 1.1V power rail

If this voltage is out of spec or goes to zero, many components on CP3260 will not function. Therefore, CP3260 will not function. The IPMC will be alive if 3.3V STBY is up. Supplies: Multiple support devices, service processor.

15

1.5V

Threshold (0x01), "Voltage" (0x02)

Voltage measurement of 1.5V power rail

If this voltage is out of spec or goes to zero, many components on CP3260 will not function. Therefore, CP3260 will not function. The IPMC will be alive if 3.3V STBY is up. Supplies: CPU I/O, FBDIMMs

16

VDD 1.8V FBDIMM

Threshold (0x01), "Voltage" (0x02)

Threshold (0x01), "Voltage" (0x02)

Voltage measurement of VDD 2.5V power rail

If this voltage is out of spec or goes to zero, many components on CP3260 will not function. Therefore, CP3260 will not function. The IPMC will be alive if 3.3V STBY is up. Supplies: Multiple support devices, service processor

18

Threshold (0x01), "Voltage" (0x02)

Voltage measurement of VDD_IO 1.2V power rail

If this voltage is out of spec or goes to zero, the CPU or HOST will not function. If all other power rails are up, the Service processor and IPMC will still function. Supplies: CPU I/O

19

Version Change

Discrete (0x6f), "reserved" (0x2b)

Firmware update event

IPMC reports event after the FW update/cold reset.

20

P48V Alarm

Discrete (0x70), "OEM reserved" (0xc0)

Voltage measurement of 48V power

Detecs either the 48V power input A or 48V power input B to power module that converts it to 12V.

21

VDD 1.8V M0

Threshold (0x01), "Voltage" (0x02)

Voltage measurement of

VDD 1.8V power rail.

If this voltage is out of spec or goes to zero, the CPU or HOST will not function. If all other power rails are up, the Service processor and IPMC will still function. Supplies: FBDIMMs..

22

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.

23

Graceful Reboot

Discrete (0x6f) "OEM reserved" (0xc0)

Monitors the state of aa graceful reboot.

This sensor logs events into the system event log when a graceful reboot timer starts, stops, or expires.
