ANS 500/132 help

Got the ANS from eBay. It doesn't work, which is how it was described. I suspect it might be the PSU but have a few questions. Do they keys being in a certain position/lock engaged a certain way stop the unit from working/not work? Anything helps and thanks.

According to this, there's a Rear Key Switch.  If that isn't locked, it won't turn on.

II. No Power at AllProblem: Unit will not power on via the front panel momentary switch. 

Probable causes: Unit not plugged in, rear keyswitch not locked, Main Logic Board or Processor Card not fully seated, hardware problem. 

Troubleshooting strategy is to verify power-on conditions are met for the machine, then isolate other hardware causes.

  1. Unit is not plugged in to a live AC outlet. Verify. If still fail THEN 
     
  2. Unit does not have the rear key switch all the way in the locked position (triple check this!) If still fail THEN
     
  3. Logic Module or Processor Card is not fully seated into the unit. Inspect the seating of the Processor Card ensuring that no gold fingers are visible where it mates into its connector. Then reseat the Logic Module, carefully and fully tightening the four thumbscrews and putting the rear keyswitch fully into the locked position. If still fail THEN 
     
  4. Plug keyboard into ADB port and press power on key. If still No Power THEN go to 5. If power on successful go to 4a. 

    a) See if machine will power down from the front panel power switch. If it does, congratulations, it's fixed. Otherwise, you've isolated to the interconnect system containing the NMI/Reset-PowerBd, the SwitchCable, the Mezzanine, and the Main Logic Module. Check and/or replace cable connecting momentary switch 922-2086. Retest. If fail then check or replace Interconnect Mez Bd. 922-2079. If fail then replace NMI/Reset Power Bd. 922-2081. If fail then replace Main Logic Module. 
     
  5. NS 700 Only: Make sure Power Supply , 661-1131, is fully seated. If fail or NS 500 THEN 
     
  6. Reset Cuda Chip (power controller IC) by pressing the red switch in the upper left hand corner of the Main Logic Module. Reseat everything firmly, making sure thumbscrews are tight and the rear key switch is in the locked position. (NOTE: Any time you execute step 6 the unit will lose its system date and time. When fixed the system date and time should be reset. If still fail THEN 
     
  7. Unplug unit and verify AC wiring by removing the Left Duct 922-2124. If all wires are seated properly then replace Power Cable 922-2090 or Power Supply 661-1131 or NS 500 power supply. If still fail THEN 
     
  8. Replace Main Logic Board.

Hap,

Key turned to the left is "Service". Straight up and down is "Run". Turned to the right is "Locked". If the panel extended over the drive bays, in the locked position the panel can't be opened. I don't recall if "locked" also inhibits keyboard/mouse input.

The rear panel has to be locked or the server won't run.

Generally, I keep the key in the run position, and use the power button to turn the machine on.

Here's a link to the setup guide:

http://www.erik.co.uk/ans/Setting_Up_Network_Server.pdf

It talks about the key positions and what they control in a couple different places. That site has a lot of ANS info, including a troubleshooting guide, RAID setup and other instructions. I really need to archive this :)

I have a full set of ANS software including the AIX update, so let me know if you need anything. I also have a running ANS if you need me to test anything out.

Generally, I keep the key in the run position, and use the power button to turn the machine on.

Thanks folks. I think some of the issue might be the switch on the back. I'm also going to replace the fuse in the power supply. For now I'm thinking about getting a toggle switch from RadioShack to jerry rig it unless I can remove it entirely and get it going. Thoughts?

The keys and locks are not identical. I found out that between my three ANS's and two 950's that the keys are not readily interchangeable.

Not for long, though I'm told. One of the ones I go to might become just a phone outlet, and stop selling all the components that they've traditionally had.

Hopefully I'm wrong.

I found a list of ~1875 that are going out of business. Luckily the ones near me aren't on that list. We will see though, I would be really sad if they went under like that. I never know when I need them but when I do, they make ish happen. 

On an aside. I DID get the ANS to boot. I did some rigging on the front lock and got it out of service mode. Sadly I'm still having issues getting it to boot to an OS.
