C-6 Netra CT Server Service Manual • February 2007
Cause
A CompactPCI board that is probably damaged is installed in an I/O slot in the
system. The board has an error causing it to continually interrupt the CPU with hot-
swap service events when there is no change to the board’s state. The board
continually reports itself “inserted” after it has been acknowledged. Because no
board is “claiming” the event, no slot number can be given. See also

# successfully taken offline
.
Action
Remove the I/O board from the server, using the instructions in Chapter 6 . If the
error message repeats, the system controller board might have failed. Try replacing
the system controller board using the instructions in
Chapter 8 .
Message
scsb#0: hsc_restore: Cannot reset disconnected slot #
Cause
The system controller board was installed in the server while the amber Okay to
Remove LED was ON for an I/O slot.
Action
Enable basic hot-swap on all the I/O slots in the server using the instructions in
Chapter 5 . Once basic hot-swap is enabled on all I/O slots, remove the system
controller board from the server.
