Where are the UPS setting in the firmware v1.06 GUI?
-
What UPS settings? The UPS function does not have any configurable options just like our DNS-343 model.
-
So what is the default UPS behavior?
- shutdown immediately?
- shutdown after X mins on battery power?
- shutdown after battery power reaches XX % left?
Any email notifications of power interruption?
-
I do not remember the the exact number off of the top of my head but I think its something like at 10% battery shut down. Will have to verify that though. No email notifications have been implemented yet.

Shouldn't these be controlled by the UPS? Maybe I'm confused...

No, the UPS just reports status,
on battery, on main power, 50% battery left, etc...
The host monitoring software contains the logic to shutdown when the (usually)
user specified conditions exist
for example,
shutdown after 5 min of battery or
shutdown immediately when main power is interrupted or
shutdown when battery reaches 10% of available power.

Please verify, and thanks for looking into this.

Here's what I found (1.06b46 beta) - if you plug a UPS - I used an APC SmartUPS 750 - into the USB port, the unit will detect and report it's status (this happens on the status page, it replaces the printer information - presumably you cannot run a print server and monitor a UPS simultaneously).
On a power failure the unit will detect and report the power failure and then run until the UPS indicates a low battery alarm at which point the DNS-323 will perform a shutdown.
The DNS-323 does not in any way allow you to configure the UPS settings - but - if you have PowerChute running on a PC you can configure it there and then disconnect and plug the DNS-323 in.
It's fairly simple logic - IF condition #1 (status=on battery) AND condition #2 (battery=low) THEN commence shutdown - this appears to be a the standard NUT implementation - I was somewhat disappointed in the philosophy of the NUT developers who apparently feel that having the host shutdown before the UPS battery is depleted is not acceptable as it means "lower availability".
NUT can apparently be configured to provide an orderly shutdown after x minutes of battery as well as client/server broadcast stuff, but, the configuration is a "non-trivial" task which I have not yet found the time to look at.

I just installed 1.06 and plugged in my UPS. Instead of the printer server status, here's what I got:
Manufacturer: APC
Product: Back-UPS ES 350 FW:823.B1.D USB FW:B1
Battery Charge: 100 %
Status : On Line
I preset the unit using PowerChute on my PC, then plugged it into the 323, which is the only appliance plugged into this UPS unit.
-
That is one approach - and one that I would use if my DNS-323 were "stand alone" - but - it's not.
It sits in a rack with a Windows server, two network switches, a firewall, a DSL modem, and two PoE injectors that feed a wireless access point and a network camera - all powered from the same UPS, total consumption ~250VA - and I would like BOTH the Windows server and the DNS-323 to be properly shutdown.
-
As a pure band-aid solution, maybe you could pick up some kind of a Y-adapter in the telephone accessories dept. of Radio Shack that can plug into the RJ-45 output on the UPS and let you plug in 2 of those USB- RJ45 cables that APC gives you.
-
My UPS (APC SmartUPS) doesn't have an RJ45 connector - it's got a USB "type B" connector and a "9 pin d-sub" connector - only one of which can be used at a time.
Essentially it's a serial interface with a built-in serial-USB adapter.
-
Take a close look at the connector on the UPS. As far as I remember it is not a standard RJ45 connector, it has 5 pairs instead of 4 or something like that. I had a UPS with no cable once and could not make a cable I ended up soldering the cable to the board in the UPS.

Maybe you should define standard RJ45 connector ;)
The correct name for the connector commonly found on UTP ethernet cables and commonly (but incorrectly) called an RJ45 connector is an 8P8C connector.
