WS-12-250 DC Power Cycling on LiFePo Batteries

[joecrowley]

Please help:
I have tried to power on two separate and brand new WS-12-250 DC by connecting them directly (with a 15A Circuit Breaker) to a 24V 100Ah LiFePo battery.

Fans will spin up, closed circuit voltage (read via multimeter) stays put. Power light comes on, and it may stay powered on long enough to boot up the http server and log in, but around that time, the switch entirely reboots itself. This is an ongoing cycle. The switch is running the latest firmware.

Any ideas? We suspect something is happening in the switch where it is not happy with the supply voltage for some reason or another.

Appreciate it,
