Still confused - Shutdown Server on Battery (PCNS) vs. Low Battery Duration

I'm sorry...I've read many posts and replies but I'm afraid I'm still confused as to the purpose of these settings.

- In the PCNS client, I have configured the 'UPS: On Battery" event to 'Shut Down System' when the event lasts 300 seconds.
- In the PCNS client, I have Configured Shutdown to turn off the UPS after the shutdown finishes.*

There's also a setting in the NMC where you can configure 'Low Battery Duration'. This is defaulted to two minutes, and I read somewhere that this is used to shutdown ALL clients if they haven't configured any shutdown events. Since my server takes up to 20 minutes to shutdown (large SQL), would it make sense to change this setting to 20 minutes in case the server doesn't shutdown via the timed event? I assume APC can shutdown the server without any additional configuration/scripts, since at this point I'm not using any command files to shutdown services/server. I may choose to add that in later.

*I don't see where you can configure how long the UPS waits AFTER it starts the server shutdown before it will shutdown the UPS, so I am assuming the APC knows that the client has shutdown before proceeding? If not, please explain how this works and if I need to configure this somewhere.

Thanks.

"That just tells you Syracuse wasn't that Griffey Shoes good," Barkley retorted. There will probably be people Air Jordan Heels who agree with Barkley that only eight Big East teams belonged in the NCAA tournament Ken Griffey Shoes as a result of the conference's awful showing, but the truth is the league simply performed well below Air Max 24 7 expectations in single-elimination format. Based on their season-long body of work, it would have been very difficult to justify leaving Nike Air Yeezy out Connecticut, Villanova or Marquette, the teams that finished ninth, 10th and 11th in the Big East regular-season standings. Even Nike Dunk Heels though he had the more logical argument, Pitino didn't exactly help himself when he looked straight into the camera and guaranteed "Notre Dame will not lose" Sunday night against Florida State. The lesson here: Never pin your TV credibility to Notre Dame in the NCAA tournament and never argue with Barkley even when you're right.
