2.7 Rear
— Power Module
Each VERSAstream has two power modules on the back. These are for dual redundant power
supplies and should be connected to two separate circuits to ensure uninterrupted monitoring. Each
power module has an AC power socket, an AC power switch, and two LED indicators labeled “AC”
and “DC”. These LED indicators function in unison with the “POWER 1”, and “POWER 2”
indicators on the front of the device.
The LEDs located next to the “AC” and “DC” labels will illuminate
green
when a power supply is
connected and switched ON.
If either LED is illuminated
red
, it indicates a defective power source. Immediate investigation is
recommended to insure redundant power integrity.
