The CMM5 (Cluster Management Module) is the latest generation of solutions for the distribution of TDD
Sync signals and “Power-over-Ethernet (PoE)” in the field. The CMM5 is a modular design with individual
4-port power injectors and an optional controller used for remote management.
Key features of the CMM5 include:
•
Support for Gigabit Ethernet (1000BaseT)
•
Modular and scalable from 4 ports to 32 ports
•
/- 48VDC input (optional AC/DC power supplies are available from Cambium Networks)
•
Uses Cambium Networks UGPS for a synchronization source
•
Dual resilient power inputs
•
Rack mountable
•
Secure remote management when used with the optional CMM5 Controller Module
•
Support for PMP 450m (cnMedusa™)
•
Future support for integration into (cnMedusa™) for cloud or NOC-based management
It consists of four subsystems, described in the following sections:
•
CMM5 Controller Module
•
CMM5 Injector (29 volt and 56 volt versions)
•
Power supply(s) (240/600 watt)
•
UGPS
