Identifying LED–Indicated Conditions
If your monitor remains blank when you power on your workstation, your system
unit's power LED may flash to indicate an error condition:
A 3/4–second flash indicates the CPU board is defective.
A three quick flash, pause, three quick flash pattern indicates a problem with
the graphics hardware. Check the monitor connections before replacing the
CPU board or the VRAM board.

Dealing with an HPMC (Uncorrectable) Error

When the hardware detects an unrecoverable (HPMC) error in the HP-UX environ-
ment, it displays an error message on the monitor. The hardware writes the state of
the system to main memory and dumps the entire contents of main memory to the
swap area on the system disk.
The system logs the HPMC error information, referred to as PIM (Processor Internal
Memory), into Stable Storage. You can display the HPMC error information from the
Boot Administration environment by using the pim command.
To identify the failed FRU(s) after an HPMC, follow these steps:
1.
Examine the 12 words listed under Other Processor Data of the data returned
from a pim command. These words represent the following data:

Compare the words identified in bold with those shown in Table 4–1 and take
the appropriate action.
