4.1.9 Mounting of HRDU
HROU has slots to enable up to four HRDU modules to be mounted in it.
You can mount a HRDU into designated slot surely. It is not possible to provide services with a
HRDU module alone; you need to connect HRDU cavity duplexer antenna port with CU’s
designated port.

The Remote Unit holds a maximum of 4 HRDUs. Guide brackets on the bottom of each HRDU slot
simplify installation as described below. MRDU installation requires a +No.1 tip size screwdriver.
