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
• Direct +/- 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
