APC UPS supply warning: Warning state: connect battery

Question

The latest racks delivered at a customer site have the newer UPS battery back-up supplies with on-screen menu.

 When they are turned on, there is a warning message that continues to flash and beep, but Battery seems charged 100% and they power up fine.  The LED to indicate Replace Battery is flashing and beeping. Have you seen this error?

 This is the first time that I have used this different type of UPS supply.  The same warning happens for both racks.

 APC UPS supply warning:  Warning state: connect battery


Answer

For the battery to connect and charge in the APS UPS units, you must open the front panel and flip the batteries for them to be ready for use.

Otherwise, you can only run off direct AC line power and batteries are not connected or charging.
