FunctionsThe PSU (AC/DC) has the following functions:

l Converts 220 V AC power into -48 V DC power and supplies -48 V DC power to theDCDU-01.

l Monitors the unit and reports alarms related to PSU faults (such as output overvoltage, nooutput, and fan faults), alarms related to PSU protection (such as overtemperatureprotection, and input overvoltage/undervoltage protection), and PSU out-of-position alarm,if any.
