sequoia system error

Dr. Serdar, unfortunately I've had this issue several times within the past 2-3 weeks, and each time it was a hard disk failure. The cause could be that the system software had a fault while trying to transfer data from the MO disk to the hard drive, or the hard drive to the MO disk. Also, if the system is not shut down properly it can corrupt the hard disk.

The MO Disk Not Ready error could also be something that is fixable if you can get the system to boot into the Service User Interface.

When the system is powered off: Hold the "Multi-Hz" toggle switch in the UP position (towards the monitor), and press the "S" key DOWN on the keyboard. Turn the system on and continue to hold these two keys. On the small LCD panel in the upper left of the system you should see "Keys Detected: 15 B0". The monitor will also have a display bar that should eventually say "Starting Service Tool".

If this never appears then it is probably a software/hard disk drive failure. I would recommend trying to get a replacement hard disk with software from the people you purchased the system from.

As a side note, is there an MO disk in the front bucket (towards the bottom of the system, at the front, there is a small door that lifts up) labeled "System backup" or "Backup" with the serial number of your system? If you have this, you can at least reload the system once you have a new hard drive with software installed on it.

Please let me know what you're able to find.

fortunatenlly i was able to go to service tool mode and i found the mo disk in the store in front of the machine and the mo disk has many backups from 2003 till 2006 and last software version was 9.51 , so this mean that the mo drive is working and also the hard drive thanks god
i tried to restore some back up files in the mo disk but  after a while it said SUI log network error or some thing like that iam not sure , and didn't work
do i need to formate the mo disk?
or what is the next step ?

thanks so much for ur help

Dr. Serdar,

** NEVER FORMAT THE BACKUP DISK** I would recommend even having two backup disks handy. I'll make a walkthrough for backing up data from your hard drive to an MO disk in a different post.

Can you tell me the model name/part number of your MO Disk Drive? I am wondering if any of the jumper settings are incorrect, perhaps maybe a jumper fell off during transit? It could also be that the MO disk drive is failing. It's not an uncommon thing, since it is exposed to dust easily, which can get on the moving parts inside the drive. If you have compressed air, you can try gently blowing out the inside of the MO drive.

As for the monitor, that shouldn't be an issue. I've replaced many monitors on these systems and have yet to see one cause an internal issue.

The next step I can think of would be try to boot to imaging. If you're capable of accessing the hard drive, and MO drive through service, it should boot to imaging. If it still doesn't, we can try doing some data resets to bring it back to a default configuration, but that might not do anything.

Well Dr. Serdar, you may have to replace the MO Drive. Were you able to try the can-of-air trick? Also, if you feel adventurous... behind and underneath the monitor (when the system keyboard area has been elevated as high as it can go) there will be a small panel that has two screws. Remove the screws and remove the panel. That should give you access to the MO disk drive.

Two screws will be holding the MO drive tray in place, these will need to be removed to slide the MO disk out of the ultrasound system. I'll put up a picture in a little bit, just need to find a system that is similar to yours.

Once the MO disk drive is out, get the model # and manufacturer name for me, and I can help you check the jumper settings. We can also try reseating the cable. Sometimes things can be knocked loose... it's not common, but it's worth checking.

Hm. I was just exploring the options that were available. I misread your statement earlier about being able to reload the information off your backup disk. I thought you said there was a SUI network log, and that it wasn't able to restore from the MO disk.

It looks like there shouldn't be any jumpers on that particular MO disk drive. If there are... pull them off and try to boot the system. I'm assuming you're still getting the "MO Disk Not Ready" error, yeah? Does the green light stay on all the time as well?

As for the data restore.. which one did you select to restore? There should be an option labeled as "SYSTEM", that will be all of the system data, try restoring that and once it's finished exit out of the service user interface to reboot the system.

helloo todd
still waiting ur reply
help me pls

dear todd
thanks for ur reply
i know it was weekend and i think thanks giving holiday
u know i restored the system with backup mo disk i have with 9.51 software it finshed smoothly to the end without error and rebooted the machine by itself but when it started same error mo drive appeared do u think it is still from hard drive?

dear todd
i use the data backup disk through service tool i go to data restore then choose the system data back up on mo disk it go smoothly to the end with out error reporting then the system reboot by itself but as it start up again same mo drive error occer
i will try the MULTIHZ and V booton to see the sequence of things and i will tell u

dr.serdar

Yeah, thats the machine not reading the hard drive then. Odd that you can still boot to the service tool.

I would recommend a software reload or a new hard drive.

I'd recommend sticking with 9.51. For the most part it's a stable software level, and with higher software levels I've encountered an image artifact that appears only on C256 systems. I don't know what it is exactly, the local Siemens engineer didn't know what was going on with it either. He had a copy of 12.221 that was loaded onto one of our C256's and until 9.51 was loaded, there was an image artifact/issue.

Hm. PUT stands for "power up test", which is basic diagnostics stuff for the Sequoia. It looks like 25 and 28 are both Transmitter tests, in board slot 1. Since it is a C256, it only has one TX and one BF (Transmitter and Beamformer).

PUT 25 - Test TX VGain Slot 1 - Ensures TX VGAIN is functional for Slot 1, Fatal Error: system will try to boot -- possible causes: TX, CN (Controller)
PUT 28 - Test TX PWG registers Slot 1 - Safety, patient exposure to uncontrolled power levels. Fatal Error: system will try to boot -- possible causes: TX, CN

There's a few problems with this though. Unless you have "Third Party Service" turned on, you cannot pull the side cover off to do any sort of board maintenance/replacing (if you do pull the silver panel/cover off, the system software prevents the Sequoia from booting to imaging, and it puts the fans on really high/fast). I was going to recommend pulling out the TX and putting it back in to see if there's a loose/weak connection. However, I would need you to enter the "Feature Control" of the system, from the Service Tool, and look for the third party service option.

If you have it, great. I'd recommend pulling the side off, and reseating the TX and CN boards. Unless the local service rep has parts, that's the cheapest/easiest way to see if maybe if things were knocked loose in shipping.

If you don't have Third Party Service, you'll need to get a service password for the day. This will also allow you to run diagnostic tests to get a clearer picture of what could be wrong with the system.
