LOL yeah, and simpler/faster to replace :-P. Unless a long steep downhill is in play here...

I mean brakes are more expensive then clutch replacements right?

They should have complete control over this. Also, are you not creating a chance for the switches to be damaged by the various power surges. Sometimes the power company will have a on/off/on/off/on cycle in power. Thus doing the same thing to your switches. This is not good for them. But, you can set the UPS units to be at a certain battery level before they will turn back on. Thus, you can protect your switches, and the UPS units. This is what they are there for - use them. ________________________________ From: Mayo, Bill [mailto:[email protected]] Sent: Monday, April 08, 2013 8:53 AM To: NT System Admin Issues Subject: UPS vs Switch Sanity Check I am in the midst of a debate with the folks who support our UPS's, and would appreciate some input. The situation was thus: We were notified of an extended power outage (6 hours) by our utility provider at a couple of our locations. At these locations we have wiring closets with switches (up to 3, in this case) that are plugged into an APC UPS. The "UPS people" wanted to go and turn off the UPS's and move the power of the switches over to a regular old surge suppressor. Their reason for this was because they contend that allowing the batteries to completely drain will damage them. They also contended that the off the shelf surge suppressor was sufficient to protect the switches from power spikes. My contention is that the switches are more valuable than the UPS's and need the protection that a real UPS affords, especially at a time where we know the power may fluctuate (spike, brownout) or blink repeatedly. I tried to do some research on whether there was any veracity to the claim about damage to drained batteries and have turned up some conflicting information. FA157446 at APC's site seems the most authoritative and says they will be OK as long as recharged within 72 hours, but I have read other comments that suggest that a total discharge will damage a UPS-type battery. What I really want is a sanity check. Is there really something to the UPS battery thing and I am being overly dramatic about the surge suppressor, or would you agree that you'd rather risk damaging the UPS (if that is even realistic) than the equipment behind it?
