This chapter describes the sensors and indicators that can be accessed through the ILOM.
Sensors report physical information about the server, including voltages, temperatures, fan speeds, and installation and removal of components. Indicators report important server conditions.
All sensors and indicators are IPMI-compliant.
Entity Presence
These sensors report the presence or absence of system components.
- P0 and P1 represent CPU 0 and CPU 1
- D0 through D5 represent DIMMs 1 through 6.

NEM and Blade Presence
These sensors indicate whether there are NEMs in NEM slots 0 and 1, and whether any blades are in slots 0 through 11.
The X6275 server module has two nodes, 0 and 1.
- Node 0 appears in the actual physical slot.
- Node 1 appears in the physical slot + 12.
For example, for an X6275 server module in slot 6, node 0 appears to be in slot 6, and node 1 appears to be in slot 18.
