+== Jan 21 ==
+replaced motherboard hardware and disks for ipp009, ipp012, ipp014. 
+
+ipp012 new disk 11 had to be swapped out. 
+ipp009: 6 4BG sticks were installed but only 5 are showing.  All the memory has been swapped out for new memory with the same result.
+ipp014: We hear continuous beeps on power on changing too 2 short
+beeps and a long one after something appears on the screen.  However
+the 2 beeps and a long on are not constant - they become random.
+We don't see any memory report on the first screen like the others.
+We changed the mother board and memory with identical results.
+There was a dead fan issue but we rewired it and all the fans are
+working and the fan light is off.  No effect on the beep pattern. The
+initial quick short beeps sound like memory beeps but it weird that we
+get it to boot at all. Left out of the rack.
+
+The new mother boards do not have an IDE connection
+for the existing optical drives.  We (Bill) drove to the only 2
+computer stores on the island and purchased the only 2 notebook size
+optical drives with sata connectors available. However - once we
+installed these we realized the connectors were something we had not
+seen - and did not have the cables for. At first glance they look like
+sata connections but there is a power component as well.  opps.
+Fortunately Brad had external usb optical drives we could use.
+Hundreds of them, in fact.  Gavin had to Mac Gyvered them in place
+because the cables were too short to set them anywhere.
+
+== Jan 24 ==
+We put the power supplies from ipp009 in and it booted
+normally. However there are still fan related alarms sounding though
+all the fans are working.  We swapped out the led/alarm board out with
+the same results. 
+
+ipp009 is up and ready for use but still short 4GB of memory.   After
+many tests  we can conclude that the
+problems lies in something other than the motherboard or memory. We
+had the same problem with a known good motherboard and memory. We
+narrowed it down to a set of black and blue memory slots associated
+with CPU0. Not the slots themselves, something that serves the slots.
+We know there is a problem with 2 slots because 12 x4GB memory sticks
+only showed 40 GB of memory.
+Also: The power supplies from ipp014 were put into ipp09 and there
+didn't seem to be any issues. Therefore we have no idea why ipp014
+started booting normally with a power supply swap.  Note: the ipp009
+memory problem occurred with the good power supplies as well. 
+
+
+== Jan 31 ==
+disk upgrades on ipp008, ipp016, and ipp021, and motherboard
+upgrades on ipp008 and ipp016.
+
+== Feb 4 ==
+
+We installed the new RAID card in ipp012 without problems.
+
+However, we did not have success with the IDE->SATA converter board
+for the CD/DVD. The drive was not being detected on boot. We tried all
+SATA ports, different card, different CD/DVD, different cable to no
+avail.  We checked the bios and there was note anything we could see
+that would prevent it from working.  The external drive has been
+reattached. We brought a card and cd/dvd player back to test it and
+get it working here. It may need a jumper set to make sure it is not
+in slave mode - however we did not have a manual or a jumper - the
+boards did not come with one.
+
+We also had the usual rack problems - ipp012 is particularly difficult
+to put back in - it is at the bottom of the rack and ipp013 is
+weighting down on it a bit.
+
+== Feb 9 ==
+Bill and I replaced the motherboards of ipp005, ipp006, ipp007, ipp025
+
+Notables:
+ipp006 & ipp025 memory counts were missing 4GB.  We identified which
+slot and put the stick in a black slot next to a blue working slot.
+All 24GB are now showing on both machines. The malfunctioning slots on
+the 2 machines were not the same. We tested the power cables and while
+we found some odd readings they were not consistent between the
+machines or relative to the cpu's with the malfunctioning slots.
+
+The boards installed on the back of the CD drive are not working.  We
+still have external CD drives hanging off the machines.
+We need to come up with a solution.
+
+At some point in time - this fix should work for ipp009 so we have all
+24 GB available.

+Voltage readings for CPU0 8pin power connector:
++5v   +12v   +3.3V

+
+Voltage readings for CPU1 8pin power connector:
+same as cpu0 except for pg was 590ms and blinking too.
+
+CPU1 slot closest to the cpu was not working.
+
+ipp025:
+Voltage readings for CPU0 8pin power connector:
+Same display for ipp006 24 pin and 8 pin cpu0
+
+Voltage readings for CPU0 8pin power connector:
+Same for CPU1 8pin.  pg 430ms
