This document pertains to I/O Board (IB) power failures in Sun Fire[TM] servers.
These boards can be fail with scenarios similar to the following (note that the voltages reported will differ from case to case, and so to the IB location):
- The symptoms described above are not an exhaustive list of messaging related to this issue. It is suspected that the real list of possible errors associated to this issue is very long, but the common symptom seems to be the voltage and power related errors shown above (and especially Path broken between CBH and SDC alerts).
- This document also applies to Sun Fire[TM] v1280, E2900, and Netra 1280, 1290 systems but are not specifically listed due to the fact that they utilize IB_SSC boards (not IBs). If this event takes place on this server type, the IB_SSC is implicated but the System Controller (which is integrated) is not reachable to even see the errors.
