Author Topic: DOLBY DSS 200 MANUAL ? Allan Barnes Expert Film Handler Posts: 108 From: GRAND BEND, ONTARIO, CANADA Registered: Mar 2009 posted 12-08-2018 07:31 PM                        I want to try an solve problems with a DOLBY DSS200 (before sending to my tech) This is NOT URGENT. (1) Anywhere online to download a service manual for the DSS200 (2) I'm getting NO power to the DCP Drives - the drives and both power supplies do work on other machines. IDEAS and HELP WELCOME.  |  IP: Logged Dave Macaulay Film God Posts: 2321 From: Toronto, Canada Registered: Apr 2001 posted 12-08-2018 08:17 PM                     Allan - I can send you a pdf of the manual. I'm surprised it isn't in this site, maybe Dolby exerted some copyright pressure? I know Kinoton would go after sites with their manuals.  |  IP: Logged Stephan Shelley Jedi Master Film Handler Posts: 854 From: castro valley, CA, usa Registered: Nov 2014 posted 12-08-2018 09:45 PM                     By DCP drives do you mean the RAID? There are at least two power connectors to it. They are part of the bundle of wires that come from the power supply cage. It is possible one or more came loose. If you mean the CRU dock then there is a power supply cable to it as well. They are all standard compute drive connectors and you can measure the DC voltage at them. It is possible you have an issue with the power supply cage itself or the RAID cage.  |  IP: Logged Leo Enticknap Film God Posts: 7474 From: Loma Linda, CA Registered: Jul 2000 posted 12-08-2018 09:48 PM                        Firstly, the Dolby Digital Cinema (DSS100/200/220 and cat862/745) installation and user manager doesn't give you any useful information for troubleshooting this problem. However, if you still want it, email cinemasupport [at] dolby.com, and I'm sure that they'd be happy to send it to you. If by DCP drives you mean the RAID drives, then I guess that your problem lies either in the RAID controller card, or in the backplane of the RAID drive cage. That is what the SATA power connectors for the individual drives are hooked to. The data connectors go through that backplane to the 3Ware RAID controller card that is in one of the PCI-E slots on the motherboard. If you can see the 3Ware RAID controller boot during the startup sequence, but it can't see any drives, then that does look like a power supply problem. If you don't see the 3Ware card booting, then it's likely that card. Either fault would result in Show Manager not being able to see any RAID.  |  IP: Logged Allan Barnes Expert Film Handler Posts: 108 From: GRAND BEND, ONTARIO, CANADA Registered: Mar 2009 posted 12-15-2018 06:10 PM                        Dave, thanks for the Manual. And yes, everyone, the Manual is useless to solve this problem. And yes, I did mean no power to the RAID. I will follow advice given but at this time is see no lose wires. (1) Will test output from Power Supply cage  |  IP: Logged Sam D. Chavez Film God Posts: 2153 From: Martinez, CA USA Registered: Aug 2003 posted 12-16-2018 11:19 AM                       There is a power supply distributor in the cage. It has to do with managing which power supply is up and and which is the backup. I had a request for one recently so I assume they do fail. Just for fun, try pulling out one supply and see if it fixes the problem. If not, put it back in the slot and pull the other supply. You can also move the supply to the other slot, etc., until you eliminate the distributor as the source of the problem. It might also reveal a bad power supply. Worth a try.  |  IP: Logged Leo Enticknap Film God Posts: 7474 From: Loma Linda, CA Registered: Jul 2000 posted 12-16-2018 11:55 AM                        Good suggestion - I once had a Doremi Showvault once that wouldn't boot up at all - orange LED on both PSUs that wouldn't go green when the power button was pressed. The fans ran for a second or two, and then all was silent. As a last ditch attempt to try to get them back up until new PSU modules arrived, I tried pulling them and swapping them around. After some trial and error, I found that if I pulled one PSU altogether and put the remaining one in the other slot (to the one in which I originally found it), the server would boot and run.  |  IP: Logged Dave Macaulay Film God Posts: 2321 From: Toronto, Canada Registered: Apr 2001 posted 12-16-2018 01:25 PM                     The Doremi 4U chassis servers (DC4 & SV4) have a known problem with the PSUs. Turned off but powered, the power supplies still make DC power for the network ports, to turn on, and other things - +5V standby. No fans run in this off but powered state. The supplies get hot. Sometimes a sensor says they are too hot to start making the high current voltages needed to turn the server on. The monitoring system that beeps when a supply fails only senses the standby power, so it doesn't beep for this. If you press the start button and see a flicker in the LEDs and maybe hear fans start then stop, followed by a normal startup in a second or two... one of the supplies is either in this hot state or has really failed, and can't make the high current voltages. Turn off one supply at a time with the unit on, the beeper will sound and the server should stay on. If it shuts off instantly the supply still on is dead (except for standby +5V).If it does stay running turn the switch back on and the other one off when the beeping stops. If both supplies are in the hot state - this shows as no starting after sitting a while powered up but not running - , switch them off for a few minutes and they will work again. If one is, and the other one starts the system, the fans will run and cool down both quickly. There is no official fix. Putting a small fan where it blows into the power supplies gives enough cooling to eliminate the problem.  |  IP: Logged Marcel Birgelen Film God Posts: 3357 From: Maastricht, Limburg, Netherlands Registered: Feb 2012 posted 12-16-2018 10:32 PM                     The manual can be found by simply Googling for it. As with most manuals, it will not solve advanced technical issues like this. I think you need to give us some more info on this one. For example, what do you need with "no power to the DCP drives"? Does it mean that the system does power up, but doesn't spin up the hard drives? If so, how far does it get while booting? Like Leo already mentioned, with the information available right now, it feels more like a 3ware RAID controller failure than a problem with the PSUs.  |  IP: Logged Stephan Shelley Jedi Master Film Handler Posts: 854 From: castro valley, CA, usa Registered: Nov 2014 posted 12-19-2018 02:03 PM                     You can pull the power connectors from the back of the RAID cage and check the voltage with a meter. It is the stand power connector used on and IDE type drive so the pinout should be 12V on one end to the pin next to it and 5V to the pin next to it on the other end. The + is the outer most pins and the two center are ground. It is a 4 pin connector. Like I said there is more than one power connector to the back of the RAID cage. I suspect each does a half.  |  IP: Logged
