Servers are not turning on after power outage

Hello!

I have a problem that during a long power outage my servers are not starting up automatically when the power comes back. My cabling can be seen in the attached image file. The servers have 2 power cordes. 1 cord is connected to a UPS with NMC card installed and manage the shutdown events. The other cord is connected to a different UPS, but that one has no NMC card installed.

I am suspecting that the problem can be that the UPS with no NMC did not drain all the batteries and one of the server PSU did not realized a missing input power event. Is this possible to happen?

I have the following APC's:
APC Matrix-UPS 5kVA (No NMC installed)
SMT3000I (with NMC)
SURTD3000XLI (with NMC)

As far as I understand the Matrix UPS and the others are from different model family and I may not be able to configure a rendundant UPS setup even if I install an NMC in the Matrix UPS.

What are my option here to achieve my goal that the servers can start up automatically.

Thank you,
PG

Hi,

Yes. The Matrix in compatible with the NMC. I do suggest test first before purchasing a new card. You can pull a card from one of the other Smart-UPS and insert it in the Matrix. Test the configuration and if all goes well then purchase a new NMC.

Hi,

The official answer is the UPS are not of the same family and therefore not compatible.

The unofficial answer is

  1. Install PCNS and configure for a single UPS.
  2. Stop the PowerChute Service.
  3. Edit the pcnsconfig.ini file and add a second UPS to the Network Management Card section. See example below.
  4. Change enrolWithNMC = false
  5. If not done in the initial configuration in the Shutdown setting set turnoffUps = true
  6. Restart the PowerChute Service.
  7. Log into each NMC and add the PCNS client to the PowerChute client list.

[NetworkManagementCard]
mode = redundant
IP_1 = 10.0.0.250
port = 80
protocol = http
enrolWithNMC = false
acceptCerts = false
IP_2 = 10.0.0.251

PowerChute will then listen to each NMC and react as configured for redundant UPS even though they are of different families. 

NOTE: The Matrix must have firmware Y or Z to be compatible with NMC.

Tank you for your answer, we will try out your solution, if indeed our apc setup is the reason for the servers not starting up.
