Re: avaya ups
Do not daisy chain UPS's. This increases the load on the UPS farther from your equipment. If you lose AC power, the farther UPS now has a greater load because it will continue to charge the batteries on the UPS that does not know that there is a loss of power. Since that UPS is charging your batteries from its' batteries, it will fail sooner.
