I recently bought a Eaton 5PX1500RTN UPS(1440VA/1440W) with a Network-MS card. I connected it via ethernet and can now see the Web UI for Eaton. This thread here gave me confidence that the UPS would work via the network instead of using the USB or Serial cable/driver. Now comes the part where I configure it with FreeNAS and pfSense router in order for it to gracefully shutdown in case of a power outage.
I want to achieve the following in case of a power outage:
Given what I want to achieve, here are some questions I have:
Note: all of the devices listed are connected to a PDU which is connected to the UPS.
I want to achieve the following in case of a power outage:
- 60 seconds into the power outage -- initiate graceful shut down of Main NAS and backup NAS.
- Keep the pfSense router, unmanaged switch, modem and DD-WRT Access Point running until the battery is 5% remaining. At that point, gracefully shut everything down including the UPS.
Given what I want to achieve, here are some questions I have:
- Do I still need to connect the "control cable" (usb or serial) even though the UPS has a network card and is visible on my network?
- Should I make FreeNAS as the master or pfSense as the Master?
- What is the advantage of making FreeNAS as master or vice-a-versa?
- In what order would a device shut down if it is a master vs a slave?
- Since my switch is a dumb switch, I believe that when the UPS shuts down at 5% battery, the switch and modem will just die due to lack of power and I am ok with that. However can the DD-WRT access point be configured to shutdown gracefully?
Note: all of the devices listed are connected to a PDU which is connected to the UPS.
