V7.5 MANUAL - Power Supply for BS41x
TetraFlex® 7.5 Manual 4-28
The PS411 is provided with a micro-controller to allow close monitoring of the actual
operating condition of the Power Supply. In addition the micro-controller also controls the
battery charging voltage.
The PS411 is connected to HDLC-bus in the Base States as well as the serial UART
interface. O&M communication is possible on both interfaces.
The PS411 is provided with internal resident settings to hold the charging configurations etc.
When used in a BS41x these settings will normally be overwritten of the common
configuration received from the active BSC at power-up. The yellow power led on front of the
PS411 will flash until the configuration from the BSC is received.
