N + 1 PSU LEDs
The Vess A2200 uses an N + 1 PSU arrangement. Each PSU has a Status LED. After boot up, check the
LEDs on each power supply on the back of the device. These LEDs will light green to indicate normal
operation. A red or amber LED indicates a problem or unit failure. See the Product Manual for a complete
description of PSU and other LED indicators.
