PDP-PO 1 Power Distribution Panel-Premium Outdoor
PDP-PO receives DC power via a rectifier and distributes it to
each block in a cabinet.
MRU-2/MRR on the RFB, AICU, UCM, and auxiliary device part receive -48 VDC from
the PDP-PO and the UCM branches the supplied power to four fans in the outdoor SPI-
2210. The PDP-PO supplies the power to each board of DMB via MBB-P and each board
uses -48 VDC supplied after converting into the required power for the corresponding
board.
Antenna Interface Control Unit (AICU)
The AICU is the unit to supply the power and to receive/transmit alarm/control
message to TTLNA (service provider’s optional device). For more detailed
