Symptoms
Here are the symptoms:
You may not see all of them upon each boot attempt though
- MAC address 0:0:0:0:0:0
- I2c error: slave did not ACK
- LOM can't boot
- SCC is missing - please insert valid SCC
- busyWait() timeout waiting for RRDY, status=0x6027c008
- ScApp PANIC No ID info
- ScApp PANIC: Fatal Software Error
- lom: SSC1: faulty i2c bus 26 detected
- lom: Inconsistent data for rocker switch
- lom: WARNING: /N0/SB0 temperature is approaching max limit of 115C
There are several causes for the symptoms.
- Missing or loose SSCC card - Causes the first four symptoms
- Ribbon cable to SSCC card reader loose / damaged - Causes the first four symptoms
- A bad IB_SSC - Could also cause most of the symptoms
- A bad power distribution board - Can cause all of the symptoms
Do not replace the baseplane (centerplane) because it is very unlikely the cause.
Below are 2 examples of the symptoms listed in the document title.
The first example is caused by a missing SSCC card or loose cable to the SSCC card reader
The second example is caused by a bad Power Distribution Board (PDB)
First Example: A Missing SSCC Card or loose SSCC Card Reader Cable

HANGS HERE FOR EVER
Additional symptoms that you might see with a bad PDB:
Sat Jan 07 23:22:58 none lom: Inconsistent data for rocker switch
Sat Jan 07 23:26:26 none lom: SSC1: faulty i2c bus 26 detected
Sat Jan 07 23:34:37 none lom: Notice: /N0/SB0 temperature is approaching warning limit of 110C.
Sat Jan 07 23:34:37 none lom: /N0/SB0 CPU 2 Temp. 0 value: 105 Degrees C
Sat Jan 07 23:34:37 none lom: FULL-COOLING ENGAGED: turning fans high
Sat Jan 07 23:40:27 none lom: Check for abnormal environmental operating conditions.
As you can see, the symptoms are more severe in the example of a bad PDB.
We get panics java exceptions busyWait() timeouts etc..
Do not replace the baseplane (centerplane) because it is very unlikely the cause
Suggested steps
- Replace Power Distribution Board
- Replace IB_SSC
