CMM4 (Rack Mount)
The Cluster Management Module (CMM) is the heart of the Cambium system’s synchronization
capability, which allows network operators to reuse frequencies and add capacity while ensuring
consistency in the quality of service to customers.
For operators who prefer indoor CMM mounting, Cambium offers the Rack-Mounted Cluster
Management Module 4. The unit is designed to be mounted onto a standard 19-inch telecommunications
rack and to allow the Cambium CMM4 to be co-located with other telecommunications equipment.
Figure 39 CMM4 (Rack Mount)
The CMM4 has two DC power inputs, one 29 V and one 56V. It can be used to power and synchronize
both 29 V legacy products such as the PMP 450 Series and 56V products such as the PMP 450i Series
simultaneously.
If the 29 V legacy products are connected to the CMM4, a 29 V power supply needs to be connected.
If the 450i Series is connected to the CMM4, a 56 V power supply needs to be connected. The CMM4
supports having two of the 56 V and two of the 29 V supplies for redundancy.
Warning
PMP 450i Series requires different wiring between the CMM4 and device. If a PMP450
Series ODU is replaced by a PMP 450i Series and the existing drop cable needs to be re-
used, the Ethernet cable adapter for CMM4 - N000045L001A" must be used between the
CMM4 and the existing drop cable.
