Green Cell UPS PowerProof 600VA with RN104
Hello community,
I bought a Green Cell UPS PowerProof 600VA as backup power for my NetGear ReadyNAS RN104.
The ReadyNAS is running at firmware level 6.10.6.
The UPS is USB connected (I tested RN104 front and back USB connectors).
- I powered down the RN104
- I connected the UPS to a RN104 USB port (front or back ... doesn't matter)
- I powered on the RN104
- the RN104 detected the UPS but the Admin - System - Overview page showed yellow status: UPS warning
When I go to the Admin - System - Power page, the UPS is listed, but as soon as I try to change a setting, the RN104 is removing the UPS from the Power page. The RN104 log documents that the RN104 failed to communicate to the UPS.
I did some reseach and understand that the ReadyNAS OS is using NUT to manage the UPS.
The NUT website does NOT list the Green Cell UPS 600VA as a supported device. Nevertheless, for Windows machines, the UPS manual advices to download a device driver from megatec. To me it looks like the Green Cell UPS 600VA is behaving like a megatec UPSilon 2000. The megatec UPSilon 2000 is listed as supported on the NUT website.
I logged into the ReadyNAS OS as root and tried to select the blazer_usb device driver by updating the /etc/nut/usb.conf file. When I update the usb.conf file with
[MY_UPS]
driver = blazer_usb
port = auto
norating
novendor
protocol = megatec
and then run 'upsdrvctl start' it reports, besides other messages, "Supported UPS detected with megatec protocol".
Nevertheless, the RN104 is not accepting the UPS. After rebooting the RN104 the /etc/nut/nut.conf and /etc/nut/ups.conf files are empty or back at default. After reboot the ups.conf includes:
[MY_UPS]
driver = nutdrv_atcl_usb
port = auto
#dashboard: ups_model =
#dashboard: ups_mfr =
serial =
vendorid = 0001
productid = 0000
The nut.conf includes
MODE=standalone
---
Can you please help me to understand what's going wrong here?
Is there a way to diagnose which manufacturer and model are being reported back by the UPS?
Is there a way to modify the /etc/nut config files so that they are not getting reset to default at RN104 reboot?
Many thanks for looking into this issue.
Regards,
Holger

Hello all,
no need to reply anymore as I'll return the UPS.
Just in case someone wants to investigate further, here is what I found so far.
The Green Cell UPS AV600 is returning the following values:
---
Jan 21 13:50:55 PrivateNAS kernel: usb 1-1: new low-speed USB device number 2 using orion-ehci
Jan 21 13:50:55 PrivateNAS kernel: usb 1-1: New USB device found, idVendor=0001, idProduct=0000

I updated the /etc/nut/ups.conf file with the following stanza:
root@PrivateNAS:/etc/nut# cat ups.conf
[GreenCell]
driver = "blazer_usb"
port = "auto"
desc = "GreenCell USV 600VA"
langid_fix = 0x409
vendor = "MEC"
product = "MEC0003"
---
... and restarted the driver/ services:
root@PrivateNAS:/etc/nut# upsdrvctl start
Network UPS Tools - UPS driver controller 2.7.4
Network UPS Tools - Megatec/Q1 protocol USB driver 0.12 (2.7.4)
Duplicate driver instance detected! Terminating other driver!

root@PrivateNAS:/etc/nut# service nut-server stop
root@PrivateNAS:/etc/nut# service nut-server start

Now the RN104 was able to "talk" to the UPS one time:
root@PrivateNAS:/etc/nut# upsc GreenCell@localhost
battery.charge: 46
battery.voltage: 11.60
battery.voltage.high: 13.00
battery.voltage.low: 10.40

root@PrivateNAS:/etc/nut#

Nevertheless, after rebooting the RN104 everything was cleared out again.
For me the issue is that the vendor ID MEC and the product ID MEC0003 are not know to the NUT driver.
Both IDs are not listed in
/usr/share/nut/driver.list
# Network UPS Tools - 2.7.4 - Hardware Compatibility List

I'm closing this thread as I decided to spend no more time on this situation.
Take care about yourselves and stay healthy.

Hi Holger GT86 and every one else here at the forum,
I've just bought the same Green Cell UPS.
When making the changes to the ups.conf file I got the same problem as you after reboot. The file got back to some kind of default.
I solved this by making the file immutable (write protect) after editing it with the following command:
# chattr +i ups.conf
And then the file stays the same.
If you later want to make changes to the file you just make mutable again with the following command:
# chattr -i ups.conf
Best regards
