DS410 does not detect Smart UPS 750

[shinank]

I had problems with my ups disappearing and getting the "There is No UPS Connection" message on my ds410. It seems to be fixed since I disabled the usb drive hibernation.

Control Panel -> Power -> General Settings tab.

Set the USB hard disk hibernate time to "none".

Worth a try.

Thanks. It was worth a try but it didnt work for me.

I can confirm DSM 3.0-1372 does not solve this issue.

Too bad... I hope they implement it the next update.

Same problem here, with Synology CS407, firmware 3.0-1337 and APC Smart-UPS 1500 VA (model number is SMT1500I).

I hope it gets solved quickly. Any news about this ?

Same problem here:
DS408 with DSM 3.0-1354
APC Smart-UPS 750VA LCD 230V (Model Nr. SMT750I)
http://www.apc.com/resource/include/techspec_index.cfm?base_sku=SMT750I

Sad to report that it does NOT work although listed that it should, see here http://www.synology.com/support/faq_show.php?q_id=300&lang=enu

@SYNOLOGY: Are you planning to fix this?? Tell us what your plans are please. Because I have to return this UPS and buy another one if you're not going to fix it...

Error Message is something like: Lost connection to UPS.

I'm having a similar problem. SMT750I, DS710+, DSM 3.0-1372. The UPS doesn't show up in the External Devices list, and the UPS tab of the Power section of the Control Panel says 'No UPS is connected'. (The UPS is plugged in to the USB port, and shows up on another computer if I connect it there.)

Hello All !

Good news: after working with the Synology support and changing things in the config files for the UPS software driver on the Synology, what worked for me ended up with changing the USB cable supplied by APC by a non-descript off-the-shelf standard USB cable.

The APC supplied cable worked well when connected to a Windows Dell workstation, but for some reason not with my CS407. I don't have time to revert my config changes and test the cable in order to know, so maybe the CS407 needs both the config changes and a standard cable to work, or only the cable.

So I would suggest to first try to change the cable, then contact support in order to change things in your config files (it's done by connecting to your box with ssh, so better do it with their help).

Hope this helps,
Paul-Henri

Changing the cable hasn't worked for me. Do you have a record of the changes that need to be made to the config files?

Thanks!

I've now been given the instructions from Support, and glory be! it works.

Here's what I was told:

Please TELNET into the DS and try the following (But we don't promise it will work in the new DSM3.0 this time, please kindly keep us updated if it can or can not work this time, it is quite important information to us).

According to compatibility list: http://www.networkupstools.org/compat/stable.html
The APC Smart UPS is not supported by usbhid-ups driver.
However, it maybe supported with some trick.

*** HOWTO:
1) If you see the /var/log/messages fulled with "Can't connect to UPS. Try to re-start driver" and run "ps | grep ups" see it stats upsd but not usbhid-ups

2) You can try to run "upsdrvctl start" and you may see the following messages: (Using APC SmartUPS 750 for example)
==============================================================

This APC device (051d:0003) is not (or perhaps not yet) supported
by usbhid-ups. Please make sure you have an up-to-date version of NUT. If
this does not fix the problem, try running the driver with the
'-x productid=0003' option. ...
==============================================================

3) Edit /usr/syno/etc/ups/ups.conf, append a productid line to the [ups] section as following.
==============================================================
[ups]
driver = usbhid-ups
port = auto
productid = 0003
==============================================================

4) Try to run "upsdrvctl start" again, and it should work!

If it does not work then the UPS is having compatible issue with the DS, and it can not be supported.

The only thing I would add is that it's probably better to stop upsdrvctl before starting it again. I didn't, but the UPS turned up in the web control after I'd rebooted the DS.

Here's what I was told:

Great ! This is what support made me change too, but I had to change my cable in the end to have it work. So I guess I was cumulating 2 problems.

Thank you!!! I am so glad you posted that.

I tried the instructions and swapping cables and mine still does not detect. Anyone have any ideas of what else I can try?

What is the output from ps | grep ups

Over five months since the last update to this thread. Does anyone know if this issue was ever fully resolved?

I think the Smart UPS 750 gives me everything I need and am considering a purchase. I see from this thread that people worked round this issue with new cables / config changes / switching off hibernation but even in combination, these changes still seemed to be a little hit or miss.

Does the Smart UPS 750 now work out of the box for anyone? Are there still examples where people haven't been able to get these two products to work together properly?

The latest version (3.1) of the DSM, which I've just installed, seems to support the 750 out of the box. At any rate, it overwrote the file I'd been instructed to change, and yet the UPS is still recognised.

You probably want to upgrade to 3.1 anyway if your machine comes with an older version.
